The crushing and screening stage in the industry is mainly composed of three-stage and a closed-circuit process. Gold ores need to go through coarse, medium, and fine crushing processes to be minimized into smaller pieces. The screening equipment is used to sieving the smaller gold ores into the proper size for the next steps.
The grinding operation usually adopts one or two ball mills with types of lattice and overflow. The second stage grinding operation forms a closed circuit with a spiral classifier or a hydro cyclone to ensure the grinding fineness.
Since traditional ball milling equipment appears some shortcomings such as fast wear and large energy consumption, many manufacturers adopt new wear-resisting rubber lining boards, sliding bearing to improve a mill operation efficiency and prolong a machine's service life.
The beneficiation stage is a crucial part of gold extraction during the whole gold ore processing plant. Placer gold mine and rock gold mine are most widely processed to extract gold concentration.
The gold slurry process of the carbon slurry method (CIP and CIL) is to put activated carbon into cyanide ore slurry, adsorb dissolved gold on activated carbon, and finally to extract gold from activated carbon.
Equipment required for carbon slurry gold mining process: Leaching mixing tank, activated carbon screen, Two-layer (three-layer) washing and thickening machine, fast desorption electrolysis system with high-efficiency and low-consumption, high-frequency dewatering screen.
It means that by ion exchange resin, gold also can be extracted from ore pulp. Like carbon, the process makes gold absorbed onto solid spherical polystyrene resin beads instead of activated carbon grains.
According to different physical and chemical properties of different types of gold ores, flotation separation utilizes various reagents to make the gold attached to the bubbles then scraping these gold particles from blades to get the concentrate.
A jigger is one of the main pieces of equipment in the gravity separation process. The jigging process mixes gold ore particles of different specific gravity together, then stratifying these particles. The minerals with small specific gravity will be on the upper layer while the minerals with large specific gravity will be on the lower layer.
A shaking table is used to process gold ores in the horizontal medium flow. The motor drives the surface of the shaker to perform the longitudinal reciprocating motion, as well as the differential motion of the washing stream and the surface of the bed. Gold ore particles are stratified perpendicular to the surface of the bed, then being separated parallel to the surface of the bed in reciprocating motion which allows gold ores with different particle sizes to be discharged from different parts to achieve separation.
It adopts lope water flow to achieve separation. With the effect of the combined force of water flow, mineral gravity, the friction created by the bottom of the tank, and ore particles, the gold ore particles will settle in different areas of the tank. The ore particles with small specific gravity will flow away with the water, while ore particles with larger specific gravity would stay.

PrincipleGold CIL process (carbon in leach) refers to add activated carbon to the pulp, leach and adsorb gold in the same time. It is an effective way to recover gold, and can reach 99% recovery rate.
PrincipleGold CIP(carbon in pulp) Process refers to an unfiltered cyanide carbon slurry process that uses activated carbon to directly adsorb and recover gold from cyanide ore pulp. Generally, carbon adsorption is performed after cyanide leaching is completed.
PrincipleGold heap leaching refers to pile up low-grade gold ore or flotation tailings on the bottom mat material, and then spray it through the NaCN solution to dissolve the gold in the ore to form a gold-containing pregant liquid and finally refine to recover gold.
PrincipleTank and vat leaching involves placing ore, usually after size crused and classification, into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the gold to leach from the ore into solution.

Mining equipment refers to equipment used for mineral mining and screening operations, generally including extraction equipment and mineral dressing equipment. In addition, cranes, conveyors, ventilators and drainage machinery are also used in mining operations. Here is the comparison of mining extraction equipment and ore dressing equipment.
There are many types of mineral processing equipment, according to the beneficiation process can be divided into the crushing machine, grinding equipment, screening equipment, classification(selection) equipment and dewatering equipment. The sorting equipment is divided into gravity beneficiation equipment, magnetic separator, flotation machine and special beneficiation equipment. According to raw materials: magnetite equipment, hematite equipment, manganese ore dressing equipment, etc. Mineral processing equipment is also used in other industrial sectors such as building materials, chemicals, glass, and ceramics.
The gold mining equipment includes: jaw crusher, hammer crusher, roller crusher, impact crusher, vertical crusher, cone crusher, ball mill, vibrating screen, spiral separator, flotation machine, mining agitation tank, ore feeder, concentrator, mine hoist, mining conveyor belt, pre-watering into a ball plate, spiral chute, beneficiation shaker, washing machine and other equipment.
After the first stage crushing process, the ore material enters the double-layer vibrating screen, the crushed upper layer material with middle layer material enters the second crushing stage, the outlet material from the first crushing stage and the second crushing stage into the screening procedure. The screened material is ground by the first stage ball mill, a closed circuit grinding system is composed of the ball mill and the classifier. The staged overflow is classified by the cyclone and then enters the second-stage ball mill for re-grinding, and then forms a closed-circuit grinding with the cyclone. The gold-plating equipment cyclone overflow firstly performs preferential flotation, and the foam products are subjected to secondary selection and a three-time selection to become concentrate products. After the preferential flotation, the tailings undergo a rough selection, a selection, and two The selection process of three selections, three selections, and one sweeping, one selected tailings and one sweeping foam product enter the cyclone for re-classification, re-selection, secondary selection and one fine The selection constitutes a closed-circuit selection, and the three selections and the second selection constitute a closed-circuit selection.
Gravity beneficiation is an ore dressing method which according to mineral density and plays an important role in contemporary mineral processing methods. The gravity separation equipment includes spiral chutes, shaker tables, jigs and short cone cyclones.
1. Mercury amalgamation-gravity separation This process involves gravity separation and then mercury amalgamation or mercury amalgamation before gravity separation. The former method is mostly used for the placer gold which with low gold content, or the surface contaminated ore. The latter is mostly used for the quartz vein gold-bearing sulfide ore. 2. Gravity separation (amalgamation)-cyanide process This gold processing method is suited for the quartz vein type gold-bearing oxidized ore which with uneven disseminated grain size and high oxidation degree, the gold-bearing ore basically free of copper, arsenic, antimony, etc. 3. Flotation process This processing method is suitable for the quartz vein gold-bearing ore, gold-bearing altered rock type ore and sulfides ore which with fine gold particle and good floatability, widely applied in the medium-large good mining plant. 4. Gravity separation (amalgamation)-flotation process This procedure is applicable to the uneven disseminated grain size and low sulfur quartz veins containing gold ore. Since the monomer-dissociated gold is recovered in a timely and early manner in the grinding circuit, the total recovery of gold can be increased. This process is a widely used process in China's gold plant, in which the recovery rate of gold can reach 30-60%. 5. Cyanidation (full mud cyanidation) process Applicable to gold with a higher emerald grain size, a deeper iron ore-bearing pyrite quartz vein type ore, or a gold-altered diorite-type ore. The ore is required to contain no elements harmful to cyanidation such as copper, arsenic or antimony. 6. Flotation-Cyanide Process This process is suitable for the treatment of gold-bearing iron ore quartz vein ore with gold and sulfide symbiosis. It is also suitable for gold-bearing granite fracture zone altered rock type ore, especially for high sulfur ore. To apply. This process is also one of the common processes in China's gold mines. 7. Flotation-baking-cyanide combined process This procedure is applicable to gold-bearing quartz vein type ores containing elements such as arsenic and antimony. The roasting process is a preparation for cyanidation in order to remove elements that are harmful to cyanidation.
