Bosite's biological oxidation gold extraction method from arsenic-containing refractory gold ores, and gold tailings dry stacking technology
Practice has proven that the gravity separation method is the most effective and economical way to process placer gold, and the gravity separation equipment can be used as placer gold Ore roughing equipment can also be used as placer gold concentrating equipment. Since the gold particle size composition in placer gold ore is different, the effective particle size limits of materials processed by various gravity separation equipment are also different, so a reasonable placer gold ore separation process is also a joint operation of several gravity separation equipment.
The gold grade of the gold-containing concentrate obtained by placer gold roughing equipment can reach /ton, and the heavy sand minerals are mostly above /ton. There are currently three methods for the selection of gold-containing coarse concentrate: gold panning After the gold particles are manually panned out, the heavy sand is discarded. A mercury amalgamation cylinder is used for internal amalgamation. After the mercury paste is obtained, the heavy sand is discarded. After the gold is extracted by manual panning or mercury amalgamation, the heavy sand is sent to a concentration plant for processing, and is processed with a magnetic Various heavy sand minerals are recovered respectively through selection, electro-selection and other methods.
The gold recovery rate of placer gold mine: the two-stage chute selection is %, the chute roughing selection, jig sweeping selection, and the shaking table selection process are %.
Therefore, there are many different types of beneficiation equipment for placer gold mines. The configuration of the beneficiation equipment needs to be determined according to the mineral composition of placer gold ores. If it is a single gold mine, a three-stage jig machine can be used for coarse beneficiation. Or use the chute jig shaking table separation process and equipment, which has good mineral processing effect, high recovery rate and low equipment investment. It is suitable for coarse and fine placer gold in small placer gold ore dressing plants.
