nickel extract from ore

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

Extraction of Nickel Nickel Ore Mining Mining

Oct 16, 2019· Extraction of Nickel. This paper introduces the extraction of nickel process and characteristics of laterite nickel ore dressing, highlights the nickel ore crushing, washing in the nickel production process design.. 1 Description of nickel ore. The laterite nickel ore is complex in composition and can be roughly divided into two types: limonite type and silicon magnesium-nickel type.

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.

Extraction of Nickel, Cobalt and Iron from Laterite Ores

The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte.

Nickel / cobalt mining extraction procedures Industrial

Sep 06, 2019· The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a mixture of materials rich in copper, nickel and cobalt and a scorifiable residue. This mixture rich in copper, nickel and cobalt is what is technically called “speiss”. Getting from this mixture to the pure metal is a complex process.
