Hard rock Gold mining

The hard rock gold processing plant can generally be divided into crushing, grinding, and beneficiation to separate the gold from rock.

JXSC supports customized hard rock gold (vein gold) mining process and uses automated, specialized separation equipment to streamline the process. From gold ore crushing, grinding, gravity separation, flotation, leaching, cyanidation, or melting, every stage of the process is refining or purifying the ore. Large processing capacity and maximize recovery rates.

Hard Rock Gold mining process

The hard rock gold mining process enables the extraction of valuable gold from rocks and ores, mainly including crushing, grinding and gravity separation to form gold processing plants. The plant is large processing capacity, low operating cost, and can recover even fine gold particles efficiently.

Crushing: In this stage, there are mainly two-stage one-closed-circuit process and three-stage-one-closed-circuit process. The jaw crusher or cone crusher is used for coarse crushing; then using fine crusher for medium and fine gold ore crushing operations.
Grinding: For the requirement of gold ore grinding fineness, a ball mill is usually used together with a classifier, and the qualified particle size is below 200 mesh.
Gravity separation: At present, gravity separation is only used to select rock gold deposits with simple structure and coarse grain size, especially the oxide rock gold deposits with high density. Gravity separation relies on large differences in density between the targetmetal (gold) and the materials in which it is found. It also requires thatthe target metal cannot be bound to the surrounding rock matrix. Mian gravity separation equipment including sluices box, spiral chute, jigs, centrifugal concentrator and shaker tables.

Dut to gold ore usually contains a variety of minerals or impurities, it is necessary to use a combination of multiple processes for separating, such as: washing, flotation, magnetic separation, electric separation, CIP, CIL, etc.

♦ rock gold processing plant

The following is a detailed description of the rock gold processing plant flow:

1. The raw ore into the hopper and then into the vibrating feeder. The material is evenly fed into the primary jaw crusher to crush large rock into medium sizes. The output material is fed into the fine jaw crusher via a belt conveyor for crushing medium-sized rocks into smaller.
2. The output material of the fine jaw crusher is fed into the vibrating screen via a belt conveyor, and the oversized stones are transported back to the fine crusher for further crushing;
3. The undersized ore into the transfer ore bin by belt conveyor, and then the fine ore is transported to the ball mill via an electromagnetic vibrating feeder to grind the ore into powder.
4. The ball mill and the spiral classifier form a closed-loop grinding device. The coarse particles are returned for another grinding, and the materials into the centrifugal concentrator by a slurry pump to separate fine gold.
5. The tailings of the centrifugal concentrator enter the sluice box to recover more gold; the concentrates of the sluice box and the centrifugal concentrator are sent to the shaking table to finely concentrate the gold.

♦ rock gold crushing plant

This setup is a 5-10tph vein gold ore crushing plant, main equipment and flow details as follows:

Jaw crusher
Hammer crusher
Shaking tables

1. The trough feeder it can feed evenly to the crusher.

2. The jaw crusher preliminary crushing of large rocks can also be made mobile type as requested.

3. The hammer crusher output size is adjustable like 10mm,5mm, etc. For this project it’s grind materials to 0-2mm, it also can be made mobile type as per request.

4. The shaking table is gravity separation to recovery gold, with very high recovery rate and it is very friendly to the environment.

This plant also can be used for hard rock tin ore, coltan ore, tungsten ore, chrome, copper, etc. The capacity can be customized as requested, such as 20tph,50tph,100tph, etc.
