Nickel element extraction, mining technique flash

The extraction process of nickel is a procedure of steps followed as in the case of copper. Certain processes executed rely on the fact if the ore is a sulfide or a laterite, accompanied with usage of high temperature refractories and smelting furnaces.

Nickel processing Extraction and refining Britannica

One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.

Nickel mine Wikipedia

From 1953 to 1958 Nickel Rim mines operating around Sudbury, Ontario deposited their mine tailings in an impoundment near the mine. The water in the impoundment was later tested and found to have low pH and high concentrations of iron, sulphur and dissolved metals such as aluminum and nickel. This is due to the oxidation of the tailings (usually sulfide minerals like pyrrhotite).

Nickel / cobalt mining extraction procedures Industrial

Sep 06, 2019 Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a “speiss”, rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.
