Copper-Nickel Ore Processing 911 Metallurgist
07/11/2019 Copper Solvent Extraction. The separation of copper from nickel is based on the fact that there is an appreciable difference in the pH at which the two metals are extracted. Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper
Copper-Nickel ores Danafloat
Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a
Nickel processing Extraction and refining Britannica
The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.
Copper Nickel Flotation
15/06/2017 Copper recovery ranged from 85 to 91 pct, and nickel recovery ranged from 60 to 71 pct; concentrate recoveries ranged from 2 to 4 wt-pct. Microscopic examination of the products confirmed that most of the sulfide minerals in the sample were liberated.

05/08/2021 The feasibility of processing low-grade copper-nickel ores by heap bioleaching was investigated. It was found that an iron-oxidizing strain of acidophilic microorganisms, Acidithiobacillus
Processing of Sulfide Copper-Nickel Ores from the Deposits
The feasibility of processing low-grade copper-nickel ores by heap bioleaching was investigated. It was found that an iron-oxidizing strain of acidophilic microorganisms, Acidithiobacillus ferrivorans, is effective in the leaching of sulfide ores from the deposits in Russia’s Murmansk region. Sulfide mineralization of the studied mineral feeds was described using the methods of X-ray phase
BENEFICIATION OF COPPER Et NICKEL ORES
C. COPPER ORES FROM BIHAR Indian Copper Complex of Hindustan Copper Ltd., are working out the copper ore deposit in Mosabani and Surda areas and processing at their Maubhandar concentrator and smelter. In addition they have set up two more concentrators at Mosabani and Maubhandar. The copper ore contains appreciable amounts of nickel which is
The beneficiation process of nickel ore,copper-nickel
24/09/2020 Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods. When flotation of
Processing of Nickel Laterite Ores on the Rise
Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.

Flotation of Nickel-Copper Sulphide Ore: Optimisation of
The nickel-copper sulphide ore used in this study was supplied by Trojan Nickel Mine located in Bindura, Zimbabwe. From the X-ray diffraction analysis, the main phases present in the ore were pentlandite (49.4%), pyrrhotite (41.2%) and quartz (4.6%), Fig.1. The ore which was supplied in lumpy form was subjected to crushing and grinding. The ore was ground to 70% passing 75 microns.

Production of nickel from laterite ores has occurred for over 100 years beginning with processing of garnieritic ores from New Caledonia. However, until now the world nickel supply has been
Norilsk Mining Centre Mining Technology Mining News
ORE PROCESSING. Norilsk Nickel’s Siberian operations include two ore concentrators, capable of treating 11Mt/y of ore, and three smelters with a combined capacity of 350,000t of copper and 160,000t of nickel. Sulphide ores are first pre-concentrated using heavy-medium separation, then treated by flotation to recover copper and nickel concentrates for smelter feed. Capacity at the Nadezhda
Extraction and Refining of the Platinum Metals
bottom layer of nickel matte is tapped intermittently. By careful control of temperature and sulphur content a nickel matte can be obtained containing little copper and all the platinum metals, whereas any gold will have followed the copper sulphide into the “tops” layer. Casting the enrichd nickel matte into pigs. These are then crushed

Copper-Nickel Alloys: Properties, Processing, Applications
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

Copper-Nickel Studies and Non-ferrous Mining Minnesota
The study also found that the ore deposits of the region contained an estimated $50 billion of minerals and that a copper-nickel industry in the region could create over 2,000 new jobs. After the study's publication, the public was both excited by the economic possibilities of a new mining industry in northern Minnesota and concerned by its possible environmental effects.
