Ore nature of gold ore crusher

Earth's total gold reserves of about 4.8 billion tons, and distributed in the core of about 4.7 billion tons, mantle 86 million tons, and distributed to the crust of only 100 million tons. More than 99% of the Earth's gold enters the core. This distribution of gold is formed during the long-term evolution of the earth. The abundance of the crust formed in the early stages of the earth's development is high, and therefore, it is representative of the early etch montene green belt, especially the mafic and ultramafic volcanic rocks, In the crust of various types of rocks, it may become the earliest "mineral source layer" of gold deposits. In summary, the abundance of gold in the crust is already very low, but also has a pro-sulfur, copper, ferrous, high melting point and other properties, to form industrial deposits, gold to enrich thousands of times The formation of large ore, rich ore, gold will be enriched thousands, tens of thousands of times, or even higher, it can be seen that the huge gold generally go through a long period of geological time, through a variety of sources, multiple mineralization superposition only May be formed.

Processing technology of gold ore crusher

Gold ore processing and production process include: broken, grinding, mineral processing three processes: In the process of crushing, the three-stage closed-circuit crushing is the most modern way to break the gold ore, to complete the ore crushing and partial dissociation work, thereby improving the subsequent grinding efficiency; Grinding process, the two sections of a closed grinding is an efficient grinding process, can make gold mining more fully;

In the beneficiation process, due to the different types and properties of gold ore, the beneficiation method is also different, but commonly used re-election, flotation, mixed mercury, cyanide and today's resin slurry method, carbon paste adsorption, New technology of France. For some types of ore, often using the joint gold process.

The first stage: broken sieving - three sections of closed circuit

Large pieces of gold ore from the silo by the vibrating feeder evenly into the jaw crusher or mobile jaw crusher for coarse crushing; shredded gold ore after the sieve through the vibrating screen, sent by the belt conveyor Single cylinder hydraulic cone crusher in the broken; broken gold ore material into the multi-cylinder hydraulic cone crusher for crushing;

The second stage: milling

Will be sifted through the vibrating screen 0-12 mm of gold powder evenly sent to the ball mill for grinding, and by the spiral classifier screening, does not meet the requirements of the ball mill is sent to continue to flour ;

The third stage: beneficiation

In the beneficiation process, due to the different types and properties of gold ore, the beneficiation method is also different, but commonly used re-election, flotation, mixed mercury, cyanide and today's resin slurry method, carbon paste adsorption, New technology of France. For some types of ore, often using the joint gold process.

Gold flotation production line

【Technology】:Flotation is the most widely used mineral processing method for the treatment of rock and gold in gold concentrator, and is often used to treat highly depleted sulfide mineral gold-bearing ores. Flotation process can maximize the enrichment of gold to the sulfide minerals, tailings can be directly abandoned, low cost of mineral processing, 80% of China's rock gold are used to sort out the process.

【Application】:Gold flotation process is suitable for the treatment of gold particles smaller, floatable high sulfide quartz vein ore and polymetallic gold sulfide ore and carbon (graphite) ore.

Gold flotation process

Gold flotation of the general use of a grinding - flotation process, can be used for the uneven size of the ore can be used stage grinding process. China generally adopted a grinding - flotation process, in order to achieve the enrichment of useful minerals.

Gold fineness requirements

Gold ore fineness requirements, in general, for the package in the sulfide minerals in the gold only need to dissociate the sulfide monomer can be, but with the gangue gold grinding fineness of the gold need to reach the monomer Dissociation. At the same time a certain kind of mineral grinding degree of fineness is determined by the test.

Gold ore flotation process pulp concentration requirements

Gold flotation principle is: flotation large density, coarse particle size, often with a thicker pulp; the other hand, when the flotation of small density, fine particle size and slime with thinner slurry, coarse selection of thicker Pulp, can guarantee a higher recovery rate, selected with a more dilute concentration, is conducive to improving the quality of the concentrate.

Other process conditions

In addition to grinding fineness, the impact of gold flotation process conditions, including pulp concentration, flotation agent dosage, inflatable, flotation time and so on need to test to determine.

General gold flotation process, the need to use the flotation agents are: collector, activator, foaming agent, etc., collectors used to promote gold floating, the activator is to increase the floating rate of gold, foaming agent Is to increase the number of flotation bubbles.
