Process For Obtaining Apatite Concentrates By Froth Flotation

Mar 15, 2013 A process applicable to different lithologies of phosphate ore with siliceous-carbonated matrix from igneous or sedimentary origin rocks includes ore preparation by comminution through crushing, grinding, and de-sliming, prior to apatite flotation. During flotation, ground and de-slimed ore pulp with high concentration of solids, above 40, is initially conditioned with depressant reagent, e.g ...

Pyrite Tailings Recovery By Flotation 911 Metallurgist

May 07, 2016 Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a ...
