Pre

2019/9/1Gravity separation is widely used in mineral processing for pre-concentration of high specific gravity rare earth elements (REE) bearing minerals (Jordens et al., 2013, Dehaine et al., 2019). In particular, centrifugal separators, such as the Falcon concentrator, are the most common gravity separators used for the recovery of fine particles ( Falconer, 2003 ). Get price

Natural Sciences Grade 9

The methods mentioned so far are all physical separation methods. Sometimes they are sufficient to separate minerals for use, like coal or iron ore. But more often the element that we are looking for is found as a chemical compound, and so will have to be separated by further chemical reactions. Get price
