Copper Nickel Arsenides Mohawk, Mi

Copper nickel arsenides collected from a large fissure at the Mohawk No. 2 mine, Mohawk, Keweenaw Co., Michigan were investigated by powder diffractometry and electron probe analysis. These materials correspond to the "keweenawite" and "mohawkite" of Koenig and the "ledouxite" of Richards. The phases identified include α-domeykite, β-domeykite, algodonite, arsenical copper, rammelsbergite ...

plant studies on various cobalt, nickel and copper arsenides. The results of HTPOX tests on various enargite concentrates are presented in Table I. Feeds to the HTPOX were all flotation concentrates, some rougher concentrates, other cleaner concentrates. All the concentrates were tested as-received, without further regrinding. The copper extractions produced on the . cleaner concentrate ...

Flotation behavior of nickel arsenide - ScienceDirect

01/11/1986  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 and its floatability decreased markedly. XPS indicated ...

cobalt processing Uses, Supply, Facts Britannica

In the copper-nickel-iron sulfide mines of Canada, Australia, Russia, and other regions, cobalt is present in place of nickel in many minerals. Cobalt arsenides, such as smaltite, safflorite, and skutterudite, with the sulfoarsenide cobaltite and the arsenate erythrite, are mined in Morocco and on a much smaller scale in many other countries ...

The Complete Classification of Minerals - Geology In

Annabergite is a secondary mineral derived from nickel arsenides such as niccolite (NiAs). Nickel, like cobalt, is a chromophore: due to its presence, annabergite is light green in color. Conichalcite (CaCu(AsO 4)(OH)) is a copper arsenate which is grass green in color and possesses a green streak. It is pigmented by copper. Olivenite (Cu 2 AsO ...

The nickel and copper concentrates were made by discovered from the Kevitsa drill core specimens, N = 336 PGM flotation and the concentrates had average 12.2 per cent Ni, and grains. 28.55 per cent Cu, respectively. These correspond to recoveries of 78.8 per cent Ni and 89 per cent Cu of the sulfides. Part of the PGM DISTRIBUTION Ni remained in the silicates. The Ni concentrate also contained ...

Mohawkite - Wikipedia

A reanalysis of the material in 1971 found it to be an intimate mixture of copper and nickel arsenides and the mohawkite name was discredited as a mineral species. Uses. Mohawkite, being a copper ore, is used for obtaining copper. However, when the copper is removed, it is toxic due to the amounts of arsenic in it. Mohawkite

EXPERIMENTAL INVESTIGATION OF THE THERMOCHEMICAL

,aq) using foils of copper, nickel, or cobalt as the reductant, at temperatures of 150ºC to 300ºC. At the highest temperature of 300°C, very limited sulfate reduction was observed with cobalt foil, but sulfate was reduced to sulfide by copper foil (precipitation of Cu 2 S (chalcocite)) and partly reduced by nickel foil (precipitation of NiS 2 (vaesite) + NiSO 4 xH 2 O). In the 300ºC ...
