Hard rock Gold mining process
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 specialized separation equipment to streamline the process. From crushing, grinding, gravity separation, flotation, leaching, cyanidation, or melting, every stage of the process is refining or purifying the ore.
Hard Rock Gold process
The hard rock gold mining process enables the extraction of valuable gold from rocks and ores. The rock gold process plant is large processing capacity, low operating cost, and can recover even fine gold particles efficiently; mainly including the following four stages.
- Crushing: Mainly using two stage-one closed circuit or three stage-one closed circuit process. The jaw crusher or cone crusher is used for coarse ore; then using fine crusher for medium and fine 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. It 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. Large processing capacity and maximize recovery rates.

♦ 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. Then output material is fed into the fine jaw crusher via a belt conveyor for fine crushing.
2. Then, the material is fed into the vibrating screen, and the oversized stones are transported back to the fine crusher for further crushing;
3. The undersized ore into the transfer ore bin, 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 re-grinding, and the materials into the centrifugal concentrator by a slurry pump to separate fine gold.
5. The tailings enter the sluice box to recovery more gold; all concentrates 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. Using shaking table to recover fine gold, then it is melted into gold bricks through a gold melting furnace.
This plant also can be used for processing hard rock tin ore, coltan ore, tungsten ore, chrome, copper, etc. The capacity can be customized as requested, such as 20tph, 50tph, 100tph, etc.
