processing of nickel ores and concentrates
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 ...
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...
Extraction of cobalt from complex ore flotation concentrates obtained from the Blackbird Mine. Idaho. USA is reviewed. After flotation of a primary copper concentrate, a bulk concentrate is recovered containing major amounts of cobalt, arsenic, and iron, with minor amounts of copper and nickel.

Processing Nickel Ores - mine-engineer. The tailings from these cells is sent to another flotation cell, to recover the nickel, and the concentrate is combined with the 3% nickel concentrate to produce a 12% nickel concentrate Most nickel ores have several recoverable metals in them and the process if commonly a multiple stream of metals recovered
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 coppersulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore.

Most nickel ores have several recoverable metals in them and the process if commonly a multiple stream of metals recovered. The copper concentrate is sent to the copper smelter and 99.99% copper cathode is produced in electrowinning cells. The nickel ore is sent to the nickel refinery, where a complex set of reactions is carried out.

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 ...

Processing of Nickel Ores and Concentrates '15 3 the ore is dissolved into the nitric acid, leaving behind the acid insoluble minerals, usually consisting of silicates, and the pregnant leach solution (PLS). The solid-liquid separation of the post-leached slurry occurs in a series of counter current decantation thickeners (CCDs).

Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
