Thiourea leaching process of Bosite low-grade gold and silver ore, thiourea gold extraction technology, centrifugal gold separator
The beneficiation method of placer gold ore is relatively simple. The ideal beneficiation effect can be obtained through screening and gravity separation. The equipment used in placer gold beneficiation is mainly trommel screen, jig, chute, mercury amalgamation cylinder, etc. Many customers question the enrichment ratio and recovery rate of placer gold by jig. As a professional jig R&D and manufacturer in China, Henan Platinum Site Machinery Manufacturing Co., Ltd. would like to briefly introduce the situation of placer gold selection for jig machines.
The jig is an early type of gravity mineral processing equipment. Its mineral processing capacity and high mineral processing recovery rate occupy the core position in the field of gravity mineral processing equipment. In the field of placer gold mineral processing, the jig also It occupies a very important position. Although the chute has a large processing capacity, its mineral processing recovery rate is very low. The gold lost through the chute's mineral processing can be regarded as an astronomical figure. The processing capacity of the jig is lower than that of the chute, but its recovery rate is much higher than that of a simple device such as the chute. According to relevant data, the recovery rate of the jig for granular gold is higher than %, and for flake gold and irregular gold The gold recovery rate is also as high as over %, making it one of the most ideal roughing equipment for gold selection.
The concentration of placer gold ore by jig is relatively high, but it is not certain. It needs to be determined according to the composition of placer gold ore. For example, placer gold ore contains more heavy minerals such as iron and tin. , tungsten and other heavy minerals. These heavy minerals will also be enriched during the jig beneficiation and enrichment process, and will eventually be mixed with gold and appear in the concentrate. Therefore, the beneficiation and enrichment ratio of polymetallic placer gold ores is often Lower than the enrichment ratio of a single placer gold mine.
Placer gold ore beneficiation generally adopts the processes of chute roughing, jig sweep, and mercury amalgamation barrel selection. The chute can increase the processing capacity of the ore to a large extent, but the gold lost in the chute needs to be increased. The final gold concentrate produced by the jig and the chute is purified through the mercury amalgamation cylinder to obtain the final gold concentrate. This is the most ideal gold separation process.
