Dense Medium Separation

With energy costs increasing and ore grades diminishing, the role of preconcentration in hard rock mining operations has been gaining greater interest. To maximize energy conservation, the preconcentration process should be conducted at as coarse a crush size as possible while minimizing losses of pay metals. Dense medium separation (DMS) is a robust process that can be conducted at particle ...

Innovations: How Hydrometallurgy and the SX/EW Process Made Copper the "Green" Metal

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copperbearing minerals from it. To be applicable to this process, the ores must contain copper minerals in sulfide form ...
