Mineral Extraction an overview ScienceDirect Topics
网页Tailings produced by mineral processing tend to be much richer in minerals and more uniform and of a finer grain size owing to milling. In some cases these materials have a high toxicity, as hazardous chemicals are used in the separation of mineral particles. The grain size of the milled rock is dictated by the process used for mineral
