Postgold concentrate roasting and pre-oxidation process, gold mine tailings recovery method

Bosite gold concentrate roasting and pre-oxidation process, gold recovery method from gold mine tailings
Gold extraction by gravity separation is one of the oldest, most common and most efficient methods of alluvial gold selection, and early alluvial gold selection equipment It is relatively backward, and most of them rely on manual hand-cranking to sort gold, so the recovery rate of alluvial gold is low and the output is also very low. Here, Henan Bosite Machinery Manufacturing Co., Ltd. introduces to you the most important, most effective and most modern modern alluvial gold sorting. Economical placer gold beneficiation methods and equipment.
In alluvial gold beneficiation, gold usually exists in the form of single natural gold, which is generally divided into granular gold and flake gold. The beneficiation process is basically the same. First, use screening equipment to screen out the large stones in the sand. , and then the placer gold ore can enter the gravity separation equipment for enrichment, and the gold concentrate enriched by gravity separation can directly enter the mercury amalgamation equipment for amalgamation to extract gold.
The placer gold screening equipment generally uses a drum screen, which is a This kind of drum screening equipment has the characteristics of simple operation, convenient maintenance, wide application range and strong screening ability. The alluvial gold gravity separation equipment is mainly jig. The jig has the characteristics of high recovery rate, large processing capacity and high enrichment ratio. It is widely used in large and medium-sized placer gold concentrators and is also mainly used on large gold mining ships. The placer gold ore is processed through trommel screen screening and jig gravity selection, and all aspects of mineral processing indicators have reached a satisfactory level. Further purification of gravity separation gold concentrate requires the use of selection equipment. The selection equipment for alluvial gold includes shakers, mercury amalgamation cylinders, etc. The selected shaking table has the advantages of energy saving and environmental protection, but its large area and low work efficiency have deterred many customers. The mercury amalgamation cylinder has high gold extraction efficiency and has the function of forced mercury amalgamation, and the gold recovery rate can reach % The above features include small floor space, easy operation, and large processing capacity per unit floor space. It has become the core equipment for amalgamating mercury to extract gold.
Small placer gold mining equipment mainly refers to: chutes, sticky gold blankets, gold pans, etc. These gold mining equipment are inefficient and far from meeting the energy-saving and efficient mineral processing requirements. In new alluvial gold mineral processing plants, jigs, New gold mining equipment such as centrifugal gold separators occupy a huge market share.
