1. Flotation Separation Processing: The flotation process is the most common gold ore beneficiation process. It is often used to process highly floatable gold-bearing sulfide minerals. The flotation process can maximize the enrichment of gold in sulfide minerals, and the tailings can be directly discarded, and the beneficiation cost is low.

2. Gravity Separation Processing: In addition to the flotation process, the gold ore gravity separation process is also mostly used in gold ore dressing plants. For gold mines where the gold is unevenly distributed in coarse and fine grains, a gravity separation device is usually installed in the pre-flotation grinding and classification circuit to recover the particulate gold in advance.

3. Gold Carbon-in-leach(CIL) Processing: The gold CIL process is suitable for beneficiation of high-grade large-scale gold mines and gold mines with high associated silver and copper content. For small gold mines, it is recommended to use fine gold ore flotation process.

The flotation of gold minerals generally adopts a one-stage grinding-flotation process, and a staged grinding-flotation process can be adopted for ores with uneven particle size. For gold mines with complex ore properties, the flotation process is also more complicated. Flotation equipment is mainly a flotation machine. XJK flotation machine is a traditional self-suction flotation machine, JJF, SF and BF flotation machine are a new self-suction flotation machine.

The principle of gold flotation is: flotation of large-density and coarse-grained minerals often use thicker slurry; on the contrary, when flotation of small density, fine-grained and sludge, use a thinner slurry, which can ensure a higher recovery rate and improve the quality of the concentrate.

The main equipment is shaking table. It is suitable for processing and sorting minerals with finer particle size. The feeding particle size range of shaking table separating gold is generally between 3mm-0.019mm. The gold beneficiation is stable and reliable, and the distribution of the ore belt is clearly visible. The rich ore is higher than other beneficiation methods, easy to manage, and the required ore can be separated at one time.

The main equipment is spiral chute. The spiral chute is suitable for processing fine-grained materials with low mud content. The material size ranges from 0.6-0.03mm. The structure is simple, the processing capacity is large, and the overall cost is low.

a complete ore beneficiation production line consists of a vibrating feeder, a crusher, a vibrating screen, a ball mill, a dryer, a concentrator, a magnetic separator or flotation machine and a spiral classifier.

The preparation usually consists of two stages: crushing and mineral grading. In order to separate useful minerals from ore, the ore should firstly be crushed. Sometimes in order to meet the requirements of the material size of the subsequent work, it is necessary to add a certain crushing operation.

The ore will be sorted after being crushed and the useful minerals and gangue are selected, or the various useful minerals are separated from each other, which is the main part of the beneficiation. The ore dressing methods include magnetic separation, gravity separation, froth flotation, electrification, and chemical separation.

Magnetic separation is perfomed in an inhomogeneous magnetic field using the difference in magnetic properties of the mineral particles. Those minerals with strong magnetism are selected by the magnetic separator with weak magnetic field, such as magnetite and pyrrhotite; whereas those with weak magnetism are sorted by that with strong magnetic field, such as hematite, siderite, ilmenite and wolframite.

The froth flotation is an essential concentration process. In this process, several kinds of particles are separated by the surface chemistry of the particles. Additionally, it can handle materials whose size is less than 0.2 to 0.3 mm and it can also be used to select intermediate products in metallurgy as well as ions, treat wastewater. As is manifested in statistics, more than 90% of non-ferrous metal is separated in a flotation separation process.

Gravity separation refers to the sorting operation based on the specific gravity of the mineral raw material particles. Gravity separation is the main processing method for selecting black tungsten ore, cassiterite, gold, coarse iron and manganese ore; and it is also widely used for rare metal ore. This method tends to cut much cost and cause little environmental pollution.

Since most of mineral processing products are wet, it is necessary to remove the moisture from the mineral processing products before smelting. Dewatering operations are often carried out by means of concentration, filtration and drying.

Concentration is the action of gravity or centrifugal force to precipitate solid particles in the beneficiation product to remove part of the water, which is usually carried out in a concentrator.

Drying, the final stage of dehydration, refers to the reducing of moisture according to the principle of heating and evaporation. However, it is only used when the dehydrated concentrate needs to be dried. This operation is generally carried out in a dryer.

The materials are firstly sent into the crusher for primary crushing through the vibrating feeder, and then into the ball mill for further grinding. After that, the crushed materials are into the spiral classifier for washing and grading. The flotation cell or the magnetic separator will further process them for ore separation. The concentrator and rotary dryer are finally used for drying and dewatering and the materials that come out of the concentrator are the valuable minerals. Additionally, the two mentioned machines are optional and you can make a decision relied on your actual needs.
