Gravity Separation Process Of Placer Gold Ore Gold Mine Processing Line
- Section : Machinery
- Category : Mining Machinery
- SKU : 1600219192642
Product Description
Placer gold has high gold content and high mining value. According to the characteristics of placer gold and the requirements of environmental protection, the gravity separation process of gold ore is becoming an indispensable part of placer gold processing.
Working Principle
Gravity Separation Process Of Placer Gold Ore:
1. Crushing Process
The crushing process consists of three stages and one closed circuit. The ore is transported to the raw ore bin by truck. The raw ore bin is equipped with a grid screen. The large particles on the screen are broken manually by a hydraulic hammer until they pass the grid screen. The ore blocks in the raw ore bin are fed into the jaw crusher by the trough feeder for coarse crushing, and then fed into the circular vibrating screen for screening and ore washing. The products under the two-layer screen are fed into the classifier, and the overflow mud from the classifier is fed into the thickener for thickening, and then fed into the ball mill in the grinding stage.
The returned sand from the classifier is sent to the powder ore bin. The upper layer of the screen and the material under the first layer of screen are fed into the crusher by the belt conveyor for intermediate crushing. After intermediate crushing, they are fed into another circular vibrating screen for classification by the belt conveyor. The material on the screen and the material on the second layer of screen are fed into the fine crusher by the belt conveyor for fine crushing. The fine ore discharge is also fed into the belt conveyor and fed into the vibrating screen by the belt, so that the crusher and the vibrating screen form a closed-circuit work. The material under the second layer of screen is fed through the belt conveyor Belt conveyor to powder ore bin.
2. Grinding and Classification Process
The ore in the fine ore bin is fed to the belt conveyor through the pendulum feeder, and then fed to the lattice ball mill. The ball mill discharges the ore into the high weir single screw classifier, the classifier returns the sand to the ball mill for regrinding, and the classifier overflow flows to the pump box.
3. Gravity Separation
Then it enters the gravity separation equipment for gold recovery. The gravity separation equipment of gold mine mostly uses centrifuges combined with reciprocating circulation concentrator for gold recovery. In this way, the recovery rate is high and the tailing running is less. Centrifuge for single gold recovery rate is high, reciprocating cycle concentrator for wrapped gold recovery rate is high, these two kinds of equipment can recover not only granular gold, but also coarse gold, sheet gold, surface gold and other fine particle gold.
