& Gold mines can be divided into rock gold mines and placer gold mines. Rock gold mines contain gold. Ore, placer gold minerals are produced at the bottom of rivers or low-lying areas. They are actually weathered from rock gold minerals. However, rock gold minerals are often associated with other minerals, such as copper, sulfur, lead, zinc, quartz, etc. The mineral processing method is relatively complex, and Alluvial gold is mostly single gold particles, as big as broad beans and as small as fine sand, with different shapes. Compared with rock gold ore, its mineral processing method is much simpler.
&The most commonly used method for selecting placer gold ore is the gravity separation method. There are many types of equipment used, including gold pans, gold sticky blankets, shakers, jigs, etc. Each equipment used has its own advantages. But in comparison, the jig machine has the highest recovery rate and the largest processing capacity.
&The jig is a gravity separation equipment with a simple structure and easy operation. It sorts minerals according to the difference in specific gravity of different substances. The greater the difference in specific gravity, the more obvious the sorting effect will be. The specific gravity of alluvial gold is about 100%, and the specific gravity of its associated waste rock is usually no more than that. There is a significant difference in specific gravity between the two, so it is a mineral that is very easy to sort. Jigs often used for sorting placer gold mines include series sine wave jigs, series sawtooth wave jigs and C/type trapezoidal jigs.
&The gold content of placer gold ore is very low, generally no more than /, and most of them are simple gold particles, which means that large pebbles and waste sand do not contain gold, so the first step in selecting placer gold is, It is to screen large pieces of waste rock. Through screening, the beneficiation efficiency of placer gold ore can be improved, the workload of jig machine can be reduced, and the overall processing capacity of placer gold ore can be increased.
&After screening, it enters the gravity separation process. Generally, for low-grade placer gold, a large gold dressing chute is used for preliminary gravity separation. The large gold dressing chute has a large processing capacity and low beneficiation cost, and is suitable for processing low-grade gold. of placer gold mines. However, the recovery rate of the placer gold chute is low, and the tailings of the placer gold chute must be swept to improve the recovery rate of the process. Therefore, a jig must be installed at the tailings end of the placer gold chute to recover the gold particles lost in the chute. The heavy sand produced by the chute and jig is a coarse concentrate. If you want to extract gold, the coarse concentrate must be further purified. The purification method includes mercury amalgamation or gravity separation, and either a mercury amalgamation cylinder or a shaking table can be used. .
