nickel smelting and crushing process

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.

What Is Nickel Smelting? (with picture) wiseGEEK

May 02, 2020 Most often, nickel smelting occurs with flash smelting, in which electricity and oxygen are combined to quickly reach the high temperature needed. Nickel ore must melt until it becomes a product known as liquid matte, which is usually around 45

Nickel processing Extraction and refining Britannica

Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles.

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Factors affecting nickel recovery from slags produced

Nickel is recovered as a by-product of the platinum-producing process operated by Anglo Platinum. The metal is mined mainly as sulphide minerals contained in platinum ores. These pass through the concentrating, smelting and converting process route and nickel is finally recovered by electrowinning.

The beneficiation process of nickel ore,copper-nickel

A basic principle for determining the flotation process is that it is better to allow copper to enter the nickel concentrate, and to avoid nickel entering the copper concentrate as much as possible. Because the nickel in the copper concentrate is lost during the smelting process, the copper in the nickel concentrate can be completely recovered.
