flotation oxidised copper ore

EFFECT OF GRINDING CHEMISTRY ON THE SULPHIDISATION .The effect of pulp chemistry on oxidised copper sulphide minerals and copper oxide minerals were first studied separately before examining a mixed system. The work completed on the oxidised sulphide mineral revealed that grinding pulp chemistry affects the flotation performance of the ore for each oxidation degree tested. For theThirty-Year Plant Practice of Sulphidisation - Flotation ...Since 1960, the Dongchuan Copper Mining Bureau, Yunnan Province, China, has treated copper oxidised ores by sulphidisation – flotation technique only to recover copper. In order to improve the metallurgical performances and economics of flotation, extensive development work has been carried out during the past 30 years: several specific flotation flowsheets have evolved .The Effect of Oxidation on the Flotation Behaviour of ...In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area isdiscusse~with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.

Copper ores - Danafloat

Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.(PDF) Flotation of an Oxidized Copper Sulfide OreDec 30, 2017· Mineralogical examinations indicated that chalcopyrite is the main valuable copper mineral present in this ore. The associated gangue minerals include pyrite, feldspar, quartz and calcite....Oxide Copper Ore FlotationPdf flotation of an oxidized copper sulfide ore.
