gold ore mining processing

The specific mineral processing flow is as follows: The extracted ore should be crushed by jaw crusher initially. When it gets the reasonable fineness, it is transported into ball mill by elevating conveyor and feeder, and is milled by ball mill. The subtle milled ore gets the next procedure: classification. There is a theory that if the weights of solid particles are different, the sedimentations will be different, and the mixed ore can be classified by screw classifier. The classified ore gets into magnetic separator. Since the specific magnetization coefficients of ores are different, the magnetic substance of mixed ore is separated from others with magnetic and mechanical force. The mineral matter, which has been separated by magnetic separator initially, is transported into flotation machine by conveyor, and different medicines are added according to different characteristics of ore, so that the needed ore is separated from others. Since the separated ore are wet, they should be dewatered by thickener initially, and dried by dryer.

gold ore grinding mill

In the mining industry, the choice of mill type primarily depends upon the properties of the mineral. As an extra-hard mineral, the gold ore calls for a high-efficiency grinding mill to receive reduction. Obviously, the ball mill can match the order of hardness. On the other hand, the grinding of gold ore requires high reduction ratio and extra-fine size. So the gold ore processing is a closed circuit, in which the oversized particles of gold ore are returned from the post milling process to be re-milled until the size of final product achieves the requirement.

Gravity Separation Line is composed of jaw crusher, feeder, high efficiency ball mill, classifier, chute and shaker; while flotation Line is composed of jaw crusher, feeder, high efficiency ball mill, classifier, mixing bucket and flotation machine. Our company can provide users with the most reasonable line equipped with the most energy-efficient equipment in accordance with their different technical requirements. The gravity separation of gold ore is separated according to the ratio difference between gold and other minerals. The more apparent the difference is, the easier to separate. Put the gold ore into cylinder screen and flow through high-pressure water. Gravel bigger than the screen hole go through chute and into tailings area by belt; While Gravel smaller than screen hole go through cyclone to jigger and flow into shaker to be primary, secondary and scavenging selection, and fine placers is produced. This method is often used for sand mining, sand gold, and also applicable for the crushed ores. And the crusher, energy-saving ball mill and classifier should be used for large ore.
