Placer gold is a kind of common gold resources, and special equipment is needed in the process of gold mining.
First, the characteristics of gold placers
Placer gold refers to sediments containing gold minerals, usually distributed in riverbeds, riverbanks, beaches and other places. Placer gold is characterized by finer particles, generally between 0.1 mm and 2 mm, with a lower content, generally less than 1 gram of gold per ton of ore.
Equipment for mining gold placers
1. Shaker
The shaker is a traditional equipment for mining and processing placer gold. Its working principle is to use water flow to separate the placer gold. There are two types of shaker: rough separation shaker and fine separation shaker. The rough separation shaker is mainly used to separate the larger particles of placer gold, and the fine separation shaker is used to separate the smaller particles of placer gold. The shaker is simple to operate and low in cost, but the efficiency is low.
2. Placer gold processing equipment
Placer gold processing equipment is a new type of gold placer mining equipment. Its working principle is to use water flow and gravity to separate the gold placer. The equipment has the advantages of simple structure, convenient operation and high efficiency, and is suitable for large-scale gold placer mining. In addition, Shandong placer gold processing equipment can also be adjusted according to the properties of the ore, making it suitable for different types of gold placers.
3. Centrifuge
A centrifuge is a device that uses centrifugal force to separate the placer gold ore. Its working principle is to put the placer gold mixture into a centrifuge and rotate it at high speed to separate the placer gold ore. Centrifuges are suitable for processing smaller particles of placer gold ore, and their efficiency is high, but the cost is high.
III. Operation steps for mining gold placer
STEP 1 Select ore
First, the ore containing gold minerals needs to be selected and processed in the mining equipment.
2. Sorting ore
The ore is washed and sorted to make its particles finer, which facilitates the subsequent mining process.
3. Selection equipment processing
The ore sand after washing is put into the mining equipment for processing, and the appropriate equipment is selected for processing according to the different properties of the ore and the mining equipment.
4. Separation of gold placers
Through the treatment of mining equipment, the gold placer is separated and a pure gold ore is obtained.
IV. Precautions
1. The equipment for mining gold placers needs to be selected according to the nature of the ore and the scale of mining.
2. During the selection process, attention should be paid to safety to avoid accidents.
3. Equipment for mining gold placers requires regular maintenance to maintain the normal operation of the equipment.
Overall, the equipment for mining gold placer is an indispensable part of the gold placer mining process. Choosing appropriate equipment and correct operation methods can improve the efficiency of mining and processing and obtain more gold resources.
