Nickel processing Extraction and refining Britannica

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

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.

Environmental Guidelines for Nickel Smelting and Refining

Environmental Guidelines for Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very different ores—lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weathering will, with time, extract and deposit it in layers at varying depths below the surface. Lateritic ores are excavated using large earth moving

What Is Nickel Smelting? (with picture) wiseGEEK

02/05/2020· The next process in nickel smelting is refining the liquid matte, which is typically done with one of two processes. With fluid bed roasting, sulfides are added to the liquid matte and the two are roasted together, eventually leaving just the nickel metal. The other process is chloride-hydrogen reduction, in which the liquid matte is kept around 1,742° F (950° C) until a reaction occurs from

Nickel smelting and refining: A long road ahead for Indonesia

When Indonesia placed export restrictions on nickel ore early last year, the plan was to encourage the country’s mining firms to develop their own smelting and processing facilities so that Indonesia could export refined ores and concentrates, which are worth more in the market than raw ones. More than a year later, Indonesia’s ban on ore exports is stimulating investment in processing

cobalt processing Uses, Supply, & Facts Britannica

In nickel smelting, most of the cobalt is recovered during electrolytic refining of the nickel by precipitation from solution, usually as a cobaltic hydroxide. But even in nickel smelting, cobalt starts to oxidize before the nickel and can be recovered from the final converter slag. In the ammonia pressure leaching of nickel, cobalt is recovered from solution by reduction with hydrogen under
