Flotation behavior of nickel arsenide - ScienceDirect

1986-11-1 · Flotation behavior of nickel arsenide. Int. J. Miner. Process., 18:191-202. 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.

Separation of Copper-Nickel by Flotation and Magnetic

2018-11-23 · Resources in the Duluth Gabbro Complex are estimated to be 4.4 billion short tons of mineralized rock grading more than 0.50 pct Cu and 0.15 pct Ni. In addition to copper and nickel, this deposit is also a significant resource of cobalt, platinum-group metals, silver, and gold.

CHARACTERIZATION OF PRECIOUS METAL MINERAL

2016-5-18 · recovered; total sulfide recovery was 90%. 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

Recovery of Platinum-Group Metals from Gabbroic Rocks ...

2012-10-26 · Platinum-group metals are found mainly as arsenides, sulfarsenides, sulfides and platinum-iron alloys in gabbroic rocks. Major losses of platinum-group metals in extraction most frequently occur during beneficiation. In the massive sulfide rocks of Minnesota’s copper-nickel bearing Duluth Complex, platinum-group minerals are in close association with arsenide

Contrasts between platinum group element contents and ...

This paper presents new data on sulfide assemblages, platinum group elements (PGE's) and halogen contents of biotites in anorthositic series rocks from the Duluth Complex. The data are contrasted with similar data from troctolitic series rocks. Sulfides occur in only trace amounts in anorthositic series rocks as interstitial grains, inclusions in plagioclase, and veinlets cutting
