Likely the BestFine Gold Recovery Equipmentbased on the enhanced centrifugal forces, like the Falcon Concentrator, hasa maximum capacity of 150 t/h. The concentrator has proven effective in various minerals sectors link gold, Cu, Sn, Coal, Iron ore, Ag, Heavy mineral and most significantly tantalum where Falcon has achieved excellent results.

Gravity concentration technique is the most simple and economical of all methods of concentration applied in mineral processing. It permits the recovery of values at coarse a size range as possible. The separation of mineral particles are generally based by exploiting the difference in density between the two minerals. At present, the gravity concentration technique is widely used for the treatment of various traditional raw materials. Tin. tungsten, chromite, iron ore, coal as well as the heavy mineral of alluvial or beach sands etc. are commonly processed by this technique. Now days lot of new and advanced equipments have been developed to separated the finely divided minerals from the gangue materials. Some of them arc reviewed here.

The Falcon Concentrator is a Fine Gold Recovery Equipment made of a rotating bowl with the smooth inclined wall. The feed slurry enters the bottom of the bowl and gets stratified along the bowl wall. The heavier material settles on the wall while the lighter particles are pushed to the lip of the bowl and discharged as the overflow. The heavier fraction settled on the bowl wall is continuously removed through a nozzle located at the top of the bowl.

Gravity concentration is the oldest beneficiation technique adopted by the mankind. Gravity concentration is simple, cheap and efficient to treat coarse high-grade ores. However the low-grade ores need to be reduced to fine sizes for better liberation and traditional gravity concentration techniques are not capable of treating fines. After the invention of froth flotation in the beginning of 20th century, gravity concentration was pushed to the back seat. But the gravity concentration made a comeback by the end of 20th century due to:

The advanced gravity concentration techniques essentially use centrifugal force to provide enhanced gravity to efficiently treat fines. Some of the successful Enhanced Gravity Concentration technologies and Fine Gold Recovery Equipment that found application in the mineral processing industry are Falcon Concentrator and Mozley Multi-Gravity Separator.

As a Fine Gold Recovery Equipment, the Falcon concentrators rely on a rotating bowl to generate high centrifugal accelerations similar to Knelson concentrators. The feed slurry rises upward over a slightly inclined smooth wall Stratification of higher-density particles occurs toward the bowl wall, and lower-density particles move toward the center of the bowl. Different models vary in the way they collect and produce the concentrate

In the semi-batch Fine Gold Recovery Unit, the upgraded product that has been forced against the bowl wall is made to move into a vertical, fluidized collection zone in the upper portion of the bowl. The collection zone consists of a number of rings that have pressurized water injected from the back, effectively elutriating and cleaning the concentrate that sits in these collection rings until a rinse cycle begins. These machines are known as semi-batch devices because they continually accept feed during the run cycle but only produce concentrate during periodic rinse cycles. Run times range from 30 minutes to several hours depending on the application, while the rinse times are generally less than a minute. The throughput rates range from 1 to 400 t/h The centrifugal accelerations range from 50 to 200 G These units are mainly used in precious metal recovery plants.

In continuous devices, at the top of the bowl is a ring of specially designed concentrate flow hoppers, followed by pneumatically controlled variable orifice valves. These valves allow for a constant stream of concentrate to be produced. The continuous Fine Gold Recovery concentrator is able to vary mass pull to concentrate by adjusting valve orifice size through changes in air pressure. Because of their high mass pull rates of 5% to 40%, these units are used in the recovery and upgrade of tin, tantalum, tungsten, chrome, cobalt, iron, fine oxidized coal, and uranium ores. The ultrafine units are designed to concentrate material below 50 um at less than 20% solids and may be typically used in deslime cyclone overflow streams.

The Falcon concentrator is another spinning batch Fine Gold Recovery Equipment designed principally for the recovery of free gold in grinding circuit classifier underflows where, again, a very small (<1%) mass pull to concentrate is required. The feed first flows up the sides of a cone-shaped bowl, where it stratifies according to particle density before passing over a concentrate bed fluidized from behind by back-pressure (process) water. The bed retains dense particles such as gold, and lighter gangue particles are washed over the top. Periodically the feed is stopped, the bed rinsed to remove any remaining lights and is then flushed out as the heavy product. Rinsing/flushing frequency, which is under automatic control, is determined from grade and recovery requirements.

gold recovery correctly : 12 steps - instructables

gold recovery correctly : 12 steps - instructables

I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as "Cupellation"*. These processes are DANGEROUS and put the user at the risk of inhaling vaporized metals. No over the counter breather will protect you from these dangers; Only lab grade isolated breathing systems can protect against metal vapors. ********************************** SEE HEALTH HAZARD ON STEP 6*************************************** **** a Side cautionary note, This process is not suitable to purify Panned Gold or KARAT (Gold Alloyed with silver.) This Guide is best suited for gold plated or pure gold object.THIS SHOULD ALSO NEVER BE ATTEMPTED INDOORS. *Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the base metals; so when they are heated at high temperatures, the precious metals remain apart and the others react forming slags or other compounds

In this instructable you will be working with basic house hold chemicals. By themselves these chemicals can be fairly harmless. The combination of such chemical which will be presented in this instructable can be EXTREMELY hazardous; By such there are a couple of safety items which are not Optional. THE FOLLOW ITEMS ARE REQUIRED. FAILURE TO OBTAIN THESE ITEMS BEFORE HAND CAN POSSIBLY COMPROMISE YOUR HEALTH. Item # 1. Breathing equipment. You will need a chemical mask rated AT LEAST as a P100. If you dont know what a P100 rating means It is your responsibility to yourself to find out. Item # 2 Heavy duty Gloves. pvc or rubber is fine, do not use Latex or Nitrile gloves. Item # 3 Safety Glasses. Any pair will work as long as It is safety rated and solvent rated.

Helpfull items which can make doing these experiments easier. 1. Borosil glass labware. 2. 2 1/2 gallon bucket. 3. a 1 gallon bucket with holes drilled in the bottom. - to be used as a strainer. 4. a 60 ounce pickle Jar 5. Coffee filters 6. Filter holder from a coffee machine. 7. Spray bottle. 8. Mini scale with the ability to measure Grams and Oz. 9. some pipettes and test tube.

I have used a number of chemicals these I have found to be the most widely available. 1 gallon of Clorox Bleach. or Sodium hypochlorate at 6% 2. Muriatic Acid 34% HCL ~ Baume. 3. Hydrogen Peroxide - 3% but no greater then 5% 4. Stumpout by Bonide. or Sodium bisulfate - 99.9% as specified in the Msds or Sodium Meta Bisulfite. You cannot substitue with these chemicals trying to do so will no give the required reactions.

I was taught by the method of Crap in Crap out. You want your materials to be as clean as possible with the least Amount of Garbage as possible. Gold fingers are typically found on PCI cards, ISA cards, or on Memory sims/dimms/etc. They create the corrosion free connection between the computer and the expansion card. This process can also be used to recover gold from CPU such as Pentium Pro, or Cyrix or older 486 and lower generation chips.

Objective of this first chemical bath is to remove a large majority the base metals, Such as nickle, zinc and copper. After cleanly removing your plated sections of computer parts. remove any visible capacitors transistors, or other components. be sure to also remove any steel or iron parts attached. These metals can foul the reaction causing poor results.Tools 100 ML beaker, 1 gallon bucket, 2 1/2 gallon bucket.Chemicals Muratic acid, and hydrogen peroxide. Materials you are looking to recover. First step, place your 1 gallon stainer bucket, into your 2 1/2 gallon wash bucket. But first place your parts to be recovered inside your 1 gallon strainer bucket. as pictured. Add enough muratic acid to cover your fingers about 1 cm above your materials. keep track of how many MLs are added. you want to keep your waste Acids to a minimum. second. To activate the solution you want to add your Hydrogen peroxide 3 - 5% solution in a 2 to 1 ratio. two parts muratic acid to one part hydrogen peroxide. after the Peroxide has been added to your muratic acid the mixture should start to bubble, and the base metals should begin to dissolve. At this point you should be wearing your safety gear because a few unfriendly fumes are being released. This process can take up to 24 - 48 hours. this works best at the temperatures of 80 - 90 F. When this has been completed you will see a batch of gold foils floating in your now dark green acid.

These foils are about 80% gold, and copper 20% In order to reach a higher level of purity a second bath is required. For that we will need to create a test Chemical called Stannous cloride or Sn CL2 This metal is essential for Identify how much gold is left in our 2nd chemical bath. For this you will need 1 beaker, and about 30 ML or muratic acid. 1 gram of tin metal powder or shot. Weigh it out using your Scale. it takes appox 4 hours to completely dissolve the tin metal shot. or instantly for the powder. The resulting solution should be bright yellow.

THIS STEP SHOULD NEVER BE ATTEMPTED without your CHEMICAL MASK. For this chemical bath I will be reproducing the process on small scale. this is by far the most hazardous step and with the most reactive wastes. For this step I am going to use a 100 ml beaker a portion of recovered foils, about 3 grams. I will be using Muratic acid, and clorox. I will be adding only enough Muratic acid to cover my 3 grams of foils, Using a Pipette I will slowly add Clorox until all of my foils have dissolved. you can use a glass rod to help felicitate the process. After your foils have dissolved the resulting solution will be a deep golden yellow maybe a little orange in color. it may be desirable to filter your solution with the coffee filters 1 more time, depending on if little bits of green plastic from the board found their way into this step.

After Dissolving ALL the foils you might notice a small amount of inductors, caps and transistors that wormed their way into the final process. This is normal. Simply Filter again using a long neck funnel and a tall flask. The resulting solution should be a Deep and bright golden yellow..

Ok, this is the exciting part and one where you get to see some real chemistry at work.. you will need: Stannous cloride created earlier, 1 coffee filter paper, 2 pipettes or glass droppers. Simply place 1 dot of recovered solution on a piece of filer paper, Next place one drop of your stannous cloride on the other. The resulting reaction should turn purple. If your did CONGRADS you have created AURIC Cloride Or Aucl3 a gold bearing solution. If your test drop didnt turn purple, add a little more tin to your stannous cloride and heat gently with a alcohol burner and BOROsiicate test tube. Repeat Test. depending on how much gold is in your solution it may appear black.

Recovering your gold in solution is one of the Coolest steps. Whats needed, a plastic spoon, and the sodium Bisulfate or Stumpout. Simply add very small amounts of stumpout, Your Mixture should start to look like the pictures I have provided. This is caused by the SO2 Gas which acts to chemically displace the gold in solution. When the reaction has finished you will have driven out a majority of the chlorine, and replaced it with Sulfur. Any gold which was trapped in the solution has now be come a brown precipitate at the bottom of your beaker. Retest with Stannous chloride, if your reaction still turns purple you need to add more stumpout. It will take appox 10 hours for the gold to competely settle, the solution should be clear at this point.

OK this is the last stop, At this point you have drained off the last ot the solution with your pipette the bottom of your beaker should be coated with what looks like dried cinnamon. THATS PURE GOLD. Put that powder onto a fire brick that has been treated with a flux material like borax. Melt the borax till it becomes glassy. Apply your powder, Heat with a MAPP torch or something more aggressive, careful not to blow your powder off the firebrick. TADA Pure 24Karat gold. TO date I have used this process to recover approx 1 pound of gold from computer chips and the like. Enjoy.... Railes. P.S. For more information about this process Visit this website. http://goldrefiningforum.com/ This is a community of some of the brightest people I have ever had the pleasure of speaking with.

Hi, i found some particles of gold mixed with a lot of copper in my filter which was for the boregole.So it's my first time dealing with this and I'm hopping to find some good answers here because I see a lot of experienced people hereSo, I bought some nitric acid, hydrochloric acid to produce the aqua RegiaMy problem is I don't wanna spend a lot before I'm sure exactly what I'm dealing withSo, I my question is: is there anything alse besides a Buchner filter funnel that I can use to filter the solution from extra particles?Thanks in advance

I was doing the steps on here one I'm having trouble with recovering the gold from liquid form and I also did a little bit of playing around with the mixture and added little bit of battery acid. Is that something I really don't want to do? Cause I did notice that the battery acid worked really well with the vinegar, provide, and drain cleaner.YES ALL IF THIS IS BEING DONE OUTSIDE..LOL

This is a very thorough instructable and really appreciate the emphasis on safety. I had a question about step10. Do both test drops get placed one over the other or each separately? Thanks hope to hear from someone.

Dip the tip of a small piece of filter paper in the gold solution and put a drop of stannous chloride on the tip that you dipped. If it turns black then sprinkle some smb(sodium metabisulfite) in solution to precipitate gold

impossible to answer with no idea of what the contamination is. Google the "reactive series of metals" and it could be a starting point. Items on the potassium end will precipitate solution metals on the gold/platinum end of the list.
