High sulfide gold ore refers to 20% 30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotationcyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly used gold processing methods for highsulfide .
It covers a series of recent nickel sulphide discoveries over a strike length of 1 kilometre hosted within a poorly exposed ultramafic komatiite sequence traceable through the property for over 10 kilometres. Grab samples collected from this zone have returned grades of % to % nickel, with anomalous copper and cobalt values.
Nickel sulphide discoveries in recent years are much smaller in the last several decades RNC''s Dumont project is the largest nickel sulphide discovery since 1960 A lack of growth in nickel sulphide production, and a reliance on laterite nickel supply, has significant implications for the nickel market
1. Introduction. The principal nickel mineral in most nickel sulphide ores is pentlandite ((Fe,Ni) 9 S 8), which is recovered primarily by froth is nearly always associated with pyrrhotite, Fe 1 − x S, and is often associated with chalcopyrite, CuFeS 2, and other iron and nickel sulphides and present can occur in a range of minerals including ...

Nickel and Copper sulphide ores need further crushing and grinding to liberate the valuable minerals from rock. The mixture, or slurry, is fed into a rotating mill, where heavy steel rods or balls grind the rock. The ore is crushed into a fine powder and mixed with water. .
The nickel sulfide fusion is the industry standard method used to determine platinum group elements. It is slow, expensive and involves the use of highly toxic carbonyl nickel powder. Its advantage is that, when combined with ICPMS detection, it gives reliable results for all of the PGE at low detection limits because these metals are ...
