Radiometric Separation in Grinding Circuit of Copper ...

2020-4-21  Lumpy ore after semi-autogenous milling in Copper–Nickel ore processing at the Talnakh factory is studied. The lumpy ore is mainly presented by sizes −80+40 and −40+20 mm. The X-ray radiometric separation tests of the lumpy ore prove their efficiency in production of concentrate and tailings. The strength characteristics and the Bond work index of the concentrate are determined. The ...

Copper-Nickel Alloys: Properties, Processing, Applications

2021-8-12  The density of copper (8.93 kg/dm 3 at 20 °C) varies only slightly with increasing nickel content (density of nickel at 20 °C = 8.9 kg/dm 3) and is 8.9 kg/dm3 for all Cu-Ni alloys specified in DIN 17 664. This aspect can also be seen in Table 7 with the physical properties of the Cu-Ni resistance alloys to DIN 17 471.

Assessment of eco-hazard of copper-nickel ore mining

2014-12-4  The authors examine oxidation of sulfide minerals in mine waste and the associated ecological problems. The highest environmental hazard is produced by fine-dispersed mill tailings, especially where sulfide content is comparable with nonmetal content of low-chemical activity. In terms of some production waste accumulations in Murmansk Region, it is shown that the eco-hazard source

Nickel: smelting, producing-Metalpedia

Flash smelting. Flash smelting (Finnish: Liekkisulatus) is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.
