&The gold content in placer gold ore is very limited. If you want to wash out gold from a large amount of river sand, It is necessary to use an efficient and energy-saving mineral processing method to extract gold with extremely low content. At the same time, the mineral processing cost must be much lower than the gross income. Only in this way can mineral processing be meaningful and economically beneficial. Therefore, the washing of placer gold ore has high requirements on mineral processing methods and equipment, and high-efficiency and energy-saving methods and equipment must be used to obtain economic benefits. So what is the method for washing placer gold and what equipment is used?
&In fact, all placer gold beneficiation is carried out by gravity separation. Only gravity separation, an ancient beneficiation method, has the advantages of energy saving, high efficiency, environmental protection, etc., and it also has a certain impact on the gold in placer gold mines. Extraction has significant results. The rough separation of placer gold ore relies entirely on gravity separation, and gravity separation or mixing can be considered for fine selection. It can be seen how common the application of gravity separation method is in the field of placer gold washing.
&Generally, the first step in the washing of placer gold mines is screening, discarding large pieces of gold-free waste rocks, pebbles and other miscellaneous rocks to minimize the impact of these waste rocks on the mineral processing process and improve the mineral processing process. processing capacity, and this can also effectively improve the effective working rate of subsequent mineral processing equipment. The coarse screen can pass through the large placer gold slide screen. The large placer gold slide screen is a slide screen welded with round steel. A flushing water pipe is set above it. The slide screen has a special angle with the ground, which can ensure that large pieces of waste rock are smoothly screened out. The main purpose of the flushing water pipe is to carry out simple desliming and disintegration, to break up excess soil and mud clumps, to ensure the free state of gold particles, and to prevent gold particles from being wrapped in the soil and lost.
&After screening and crushing, 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 large processing capacity and low beneficiation costs, so it is suitable For processing low-grade placer gold ore. 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. In order to purify gold, the coarse concentrate must be further purified. The purification methods include mixing or gravity separation, using mixers or shakers, and centrifugal gold separation. All machines are available.
&The washing and separation of placer gold ores requires the use of chutes, slide screens, jigs, mixing drums, centrifugal gold separators and other equipment. However, the specific selection of which equipment can be used together to achieve the best mineral processing effect needs to be based on actual conditions. The situation is determined. The properties of each mineral are different. Designing a reasonable mineral processing process and equipment configuration according to the actual situation and local conditions is the first step to successful mineral processing.
