Pyrometallurgy of copper–nickel–iron sulphide ores: the ...

Jan 01, 2008  A basic principle of many processes for extracting copper and nickel from sulfide ores is to overlay the molten ore or matte with a lime–silica–iron oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidizes and as a result, partitions to the slag phase, while some of the sulfur is carried off as sulfur dioxide.

Extractive metallurgy of nickel [SubsTech]

May 31, 2012  Extraction of nickel from sulfide oresis carried out by the following process: Crushing and grinding the ore in order to free the gangue from the nickel sulfide mineral. Concentrating – separation of the nickel sulfide mineral from the gangue.

Extractive Metallurgy of Nickel, Cobalt and Platinum

Cobalt is also produced from Central African copper—cobalt ores. Platinum group metals are extracted from sulfide ores. Certain amount of nickel, cobalt and platinum group metals are produced from recycled end of used scrap. These methods help in conservation of energy and earth's resources.

Sulfide Ores - an overview ScienceDirect Topics

Sulphide ores that are mined for nickel and cobalt typically contain 1.5%–3% Ni and 0.05%–0.1% Co. Concentration, Smelting and Converting to Matte The sulphide ores are concentrated, smelted and converted to metal-rich matte. A schematic diagram of this process is shown in Figure 1.6. The processing steps are as follows:

Extractive Metallurgy of Copper ScienceDirect

Pure copper metal is mostly produced from these ores by concentration, smelting, and refining. About 80% of the world's copper-from-ore is produced by concentration/smelting/ refining of sulfide ores. The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide, and chalcocite ores.

Innovations: Introduction to Copper: Mining Extraction

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

NICKEL AND COBALT ORES: FLOTATION

The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde
