SCROLL DOWN TO VIEW OUR SPIRAL WHEEL CONCENTRATORSAfter hand panning you will always end up with black sand still in the gold. The micro-sluices and small blue bowls work well but are very slow and you will probably still end up with black sand in your gold. But with a good spiral wheel concentrator properly set up you can process 50 to 150 lbs. of black sand concentrates an hour with very little effort and have clean gold ready to display or sell.So, if you mine for gold and do not want to sit around for backbreaking hours panning and then picking out the black sand by hand you need to consider an automatic spiral wheel gold concentrator.To successfully get clean gold from a spiral wheel two things are necessary, a well designed, high quality wheel, and the knowledge to operate it properly.We have been asked many times if black sand concentrator wheels are effective. My answer is always, "it is an excellent wheel but is limited by the skill of the operator." If you do not understand the principles of gravity separation, the importance of classification, and the proper operation of the wheel, your results will probably be disappointing. Take the time to practice and experiment. SCROLL DOWN TO VIEW OUR SPIRAL WHEEL CONCENTRATORSFINE GOLD SEPARATION TIP: The importance of classifying your material: Black sand concentrates are a combination of heavy minerals usually with magnetic iron being the main mineral. These dense minerals have a specific gravity in the 5 to 6 range. Gold has a specific gravity of 15 to 19.3 depending on its purity. The black sands will weigh 1/4 to 1/3 as much as the gold. A cubic foot of black sand will weigh about 225 lbs. Or 26.7 lbs. per gallon. These heavy black sands present the major problem in fine gold recovery for recreational gold miners.Gold, with a specific gravity of 15 to 19.3, and black sands at 5 to 6, when properly screened down to approximately the same size, will allow the gold to be easily separated using a good spiral wheel concentrator. Without proper screening (classification with a sieve), particles many times the size of the gold will climb the spirals and disturb the concentrating action of the water and gravity. As the gold climbs up the spirals this disturbance can cause small grains of black sand, along with the large pieces, to follow the gold up to the center tube and be deposited in the pan. The best rule of thumb to follow is: "The finer the gold, the finer you want to screen your concentrates." Run the material in several different batches of finer and finer material. With proper screening and wheel operation it is possible to recover microscopic (micron) gold down to almost 500 mesh with a high quality gold spiral wheel.

humphreys spiral concentrator

humphreys spiral concentrator

Since it was introduced in 1943 to recover chromite from Oregon beach sands, the Humphreys spiral concentrator has proved successful in several fields of wet mineral beneficiation. By the end of 1957, 9390 Humphreys spirals had been manufactured. Most of these are still in service.

Requirements for Spiral Concentration: Valuable heavy minerals to be recovered must generally be 14 + 200 mesh, but outstanding examples will be discussed later where these size ranges are exceeded in commercial practice at both ends of the size scale.

by these requirements for spiral concentration. The separation of mica and vermiculite from gangue minerals such as quartz, feldspar, and ferromagnesian minerals is dependent on the flaky shape of the micaceous minerals rather than on a significant difference in specific gravity.

Phosphate rock is another application where specific gravity differences are not involved in spiral separation. The phosphate rock pulp, generally 28 mesh, is reagentized at high pulp density with the usual reagents involved in phosphate rock flotation, such as fuel oil and tall oil. Stated simply, in the reagentized pulp the quartz gangue is wetted by water and the oiled phosphate rock is not. The wetted quartz gangue settles to the inside or lower part of the spiral channel where the velocity is low and is removed as a tailing via the normal heavy mineral draw-off port, which on most other ores delivers heavy mineral.

Fine coal below x 0 can be cleaned with Humphreys spirals. The model 24-C spiral used for coal cleaning has six turns of the helix in about the same headroom required for five turns in the model 24-A metallurgical spiral. In other words, the pitch is flatter. Only in the Pennsylvania anthracite region are there commercial plants for cleaning fine coal, but numerous pilot plant tests have demonstrated that many bituminous coals respond well to spiral treatment.

A very simple system has been devised by the Humphreys Investment Co. engineers to avoid such difficulty almost entirely and permit a multi-stage spiral plant to operate on coarse feed. The rougher spiral concentrate is composed of all sizes of heavy minerals present in the feed, but the gangue content is generally finer than 28 mesh. Consequently, treatment of the rougher concentrate in the simple elutriation or single-pocket sizer produces an underflow of very high grade heavy mineral that is finished coarse concentrate. The overflow, stripped of coarse heavy mineral, is ideally suited for the feed to the cleaner spiral section.

Field of Application: Processing Florida beach sands for the recovery of ilmenite, rutile, zircon, stauriolite, and monazite is the largest single type of application of Humphreys spiral concentrators. The ore is ideally suited to spiral concentration, since it completely satisfies the requirements for successful spiraling. The size range is substantially 100 pct 35 mesh + 200 mesh, the minerals are completely liberated, and there is significant difference of specific gravity between the gangue and heavy minerals.

Humphreys Gold Corp., mining affiliate of the Humphrey Investment Co., operates three plants in Florida under various contract agreements with E. I. du Pont de Nemours & Co. and the National Lead Co. There are 3374 spirals35.9 pct of all spirals manufactured up to the end of 1957employed in the three Florida beach sand plants.

The northern U. S. iron ore ranges account for the second largest group application of Humphreys spiral concentrators. On the iron ore ranges there are 1712 spirals, or 18.2 pct of all spirals manufactured to the end of 1957.

It would be worthwhile to discuss in detail some areas where the Humphreys spirals are definitely not suitable. With one exception, spirals have no application in recovery of sulfide minerals, where flotation has been shown to do a satisfactory and superior job.

The installation in 1948 of a Humphreys spiral concentrator section at the Hill-Trumbull plant of The Cleveland-Cliffs Iron Co. is the latest commercial method on the Mesabi Range being used for the recovery of fine iron ore. In two stages of concentration 84 spirals treat approximately 120 long tons per hour of minus 1/8 in. ore. These spirals augment the production of the heavy-density plant which recovers the plus 1/8 in. iron from the plant crude ore. Structure of the ore is such that, when crushed, about 50 pct of the plant crude is minus 1/8 in. size. After desliming in a 66 in. Akins classifier, grinding the classifier product in a ball mill and again desliming in a 78 in. Akins classifier about 15 pct of the crude ore remains to be treated in the spiral plant.

Overall recovery of the ball mill feed in the Hill-Trumbull spiral plant during the 1948 season was about 53 pct of the weight and 66 pct of the total iron content. Of the actual feed delivered to the spirals from the 78 in. classifier 64.9 pct of the weight was recovered containing 73.7 pct of the total iron. The average analysis of the spiral concentrate is 55.05 pct Fe and 14.83 pct SiO2.

Preparation of ore for the heavy-density plant is near standard practice. A slight divergence begins where the minus in. size material leaves the 66 in. Akins classifier as a product and is routed to a 6 by 10 ft Allis-Chalmers ball mill. The ball mill operates in open circuit, is charged with 2 in. diam balls, driven by a 200 hp motor and has a throughput of approximately 150 long tons of solids per hour. Pulp density in the mill is approximately 65 pct solids. The purpose of the ball mill is to subject the ore to a differential grind which liberates silica from the iron ore particles, and middling from the ore particles and from silica. It also assists in breaking down porous iron oxide particles. The ground product flows into a 78 in. Akins classifier which makes a size separation at nearly 200 mesh. The slime or overflow waste analyzes about 25 to 30 pct Fe and 50 to 60 pct SiO2. Classifier product containing about 75 pct solids drops onto a 4 by 8 ft

All 84 spirals are policed by one operator who removes extraneous matter from the spirals, adjusts pulp density of spiral feed, and adjusts splitters and quantity of wash water. He also has time for additional duties including sampling and tending to the ball mill, pumps, classifiers, and screen.

Spiral operators are easily trained and after a reasonable length of time can become proficient. They are required to observe structure of the ore and to note changes which would suddenly increase or decrease the pulp density. When such changes occur, water is added or decreased to maintain the proper pulp density and launder make-up water. Occasionally, the Hill-Trumbull plant crude ore does not provide a sufficient amount of minus 1/8 in. material to adequately feed the spiral section. Before ringing for more feed the spiral operator consults the heavy-density plant foreman to determine how much more feed his section can stand. If the heavy-density plant is operating at maximum capacity and there is not enough orecoming to the spirals, this material is pumped to the 60 in.

The 6 by 10 ft Allis-Chalmers ball mill was fed 150 long tons of solids per hour. Preliminary laboratory tests on this ore showed a distinct advantage in both grade and recovery if the fine ore were given a differential grind. Grinding is fast and in open circuit. Table 5 shows the size distribution before and after abrasion grinding giving analysis of samples from a single shift and illustrating results obtainable from abrasion grinding of this ore.

In spiral concentration of an ore in which a large percentage of the weight and values is in the plus 35 mesh size, it is usually necessary to operate with a feed pulp density of about 40 pct solids and a pulp rate of 25 to 30 gpm.

In this study, a three-level BoxBehnken factorial design combined with Response Surface Methodology (RSM) for modeling of process parameters of spiral concentrator for the separation of ultrafine chromite has been developed. The three significant operational parameters of spiral concentrator, such as feed rate (m3/h.), feed pulp density (% solids by wt.), splitter position (radial distance from the central axis in cm) were considered for the investigation. The obtained results were evaluated with the BoxBehnken factorial design, RSM and also Quadratic Programming (QP). Second-order response functions were produced for Cr2O3 in terms of grade (%) and recovery (%) of the concentrate fraction. Taking advantage of the QP, it was observed that maximum grade of 51.05% Cr2O3 achieved at the feed rate of 1.2m3/h, feed pulp density of 14.81% solids by wt. and splitter position of 12cm. Similarly, maximum Cr2O3 recovery of 46.73% can be achieved at the same feed rate, feed pulp density of 10% solids by wt. and 16cm of splitter position. Predicted values of responses obtained using model equations were in good agreement with the experimental values. The influence of the process variables of the spiral concentrator on grade and recovery of concentrate fraction was presented and discussed.

In this study, modeling of spiral concentrator for concentrating the ultra-fine chromite was investigated.
