Siderite On Gold Processing

Since 2004, the processing of the iron oxide–copper–gold (IOCG) ore of Guelb Moghrein, Akjoujt, Mauritania, has resulted in the generation of approximately 40 million tons of mine tailings. The storage of these tailings poses significant environmental challenges particularly to surface and underground water resources. To address this issue, we propose an approach …

(12:03:04) 8 Types of Iron Ore Magnetic Separator. (04:03:13)

The beneficiation method of siderite is not only flotation process, but also gravity separation, magnetic separation, magnetic separation roasting and other methods can be used to separate siderite. But for fine siderite, the flotation process is extremely suitable. The flotation method uses the different hydrophilicity of mineral surface to separate minerals.

Hydrothermal alteration with bleaching of host rocks is the most important prospecting indicator for gold deposits in the Jiangnan Orogen Belt. The alteration has been identified as pre-ore carbonate (siderite)-sericitization and the Fe of siderite in the alteration zone is derived from the host rocks rather than fluids. In addition, such alteration decreases in …
