Flotation behavior of nickel arsenide ScienceDirect

Nov 01, 1986· Abstract. Platinum group minerals are closely associated with nickel arsenides in copper-nickel sulfide bearing Duluth gabbro. To improve their flotation recoveries, the flotation behavior of nickel arsenide was investigated. Nickel arsenide floated well with xanthate and mercaptan. However, nickel arsenide was extremely susceptible to oxidation

Characterization of precious metal mineral occurrences in

In a sulfide flotation beneficiation process, it is assumed that precious metals are contained within sulfide minerals as small (micron-sized) platinum group minerals (PGM), as Au-Ag minerals, or in solid solution. The 75% recovery implies that some precious metal mineral (PMM) phases may not be hosted by sulfide minerals.

Extractive Metallurgy Natural Resources Research

Previous research included copper-nickel-sulfide flotation and hydrometallurgical processing for recovery of high-purity iron, copper, nickel, and platinum-group metals. Currently, ilmenite processing is conducted via gravity (spiral) separation and hydrometallurgical techniques for recovery of high-purity iron, titanium, and vanadium.
