Nickel and Cobalt Production - ScienceDirect

Jan 01, 2014  Sulfide ores are amendable to mineral beneficiation. Comminution followed by flotation produces an enriched mineral concentrate. Sulfide concentrates are typically treated by smelting and converting to produce a nickel-rich matte. The matte can be processed by pressure acid leaching, chlorine leaching, carbonyl refining, or electrorefining.

Sulfide Ores - an overview ScienceDirect Topics

An alternative to intensifying the rate of leaching of concentrates is to heap leach the whole ore. This has the significant advantage of eliminating the concentration of the sulfides, which is the step that has the lowest recovery on route from ore to metal. Nickel sulfide ores are processed by heap leaching in Sotkama, eastern Finland ...

Nickel processing - Nickel processing - Extraction and refining: 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 ...

Processing of Nickel Laterite Ores on the Rise

Nickel is most widely used in the production of stainless steel. 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 ...

Nickel: smelting, producing-Metalpedia

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then ...

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

Nickel Ore Mineral Processing - hotminingepc

When floatability difference happens to the various nickel elements in the raw ore, the nickel ore can be recycled from tailings after the copper and nickel did the mixing flotation. Copper- Nickel Ore Flotation Process: A basic principle of copper-sulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore.

A new source, New Caledonia in the South Pacific, came into production about 1877 and dominated until the development of the copper-nickel ores of the Copper Cliff–Sudbury, Ontario, region in Canada, which after 1905 became the world’s largest source of nickel. By the late 1970s, production in Soviet Russia had exceeded that in Canada.

How clean can the nickel industry become? McKinsey

On top of that, with nickel being one of the most technically challenging metals to process and refine, and every operation being unique, further challenges will also be asset dependent (Exhibit 1). For miners, the type of ore deposit—sulfide or oxide (or laterite, further subdivided into saprolites and limonites)—defines the whole value chain.
