and gravel) and classifiers ( hydrocyclone in case of smaller particles). In case of unconsolidated deposits ( placer deposits), the minerals are generally heavier than the silicate and other gangue with which they may be mixed. Thus, traditional gravity separation methods (, shaking table, heavy media separation, etc.) and modern

Aug 03, 2019· When flotation of various nonferrous metal sulfide minerals (such as copper, lead, zinc, etc.) with xanthate collectors, the ore usually contains a certain amount of iron sulfide minerals, such as pyrite, marcasite, pyrrhotite, arsenopyrite, etc., inhibiting iron sulfide minerals with lime helps the target minerals to float.

SPA is highly efficient when used to flocculate colloids in nativesolids muds, clearwater muds and wastewater cleanup. The polymer chain links together colloidal solids that can be removed by gravity settling in shallow pits or by applying hydrocyclone, centrifuge or filtration techniques.

Jul 08, 1980· The polyhydroxy alkyl xanthates will tie up the pyrite, marcasite, and organic sulfur compounds, eliminating thus all of them as active factors in the process of froth flotation. Pyrite, marcasite, and organic sulfur compounds will exhibit no tendency to contaminate the coal concentrate, or the metallic or nonmetallic concentrates.
