nickel sulphide ore beneficiation
Copper ores Danafloat Home
The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4).

Selective precipitation of mixed nickelcobalt hydroxide
Research Highlights Cobalt precipitates prior to nickel contrary to thermodynamic predictions. Manganese precipitates prior to thermodynamic prediction for manganous hydroxide. De aerated manganese precipitation occurred at significantly higher pH than aerated experiments. Precipitate feed contacting results in higher purity MHP.
The Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals
Platinum is produced in South Africa by Amplats, Impala
Smelting. Smelting is intended to separate the gangue (oxide and silicate) minerals from the sulphide minerals associated with the noble metals.
Atmospheric acid leaching of nickel laterites review Part
This review first considers the mineralogy and reactivity of nickel laterites including selective leaching of various ore types (viz. limonite, smectite, saprolite).It then examines developing technologies that focus upon the following
