Nickel Mining and Processing Everything you Need to Know

Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most well-known purification processes is called the Mond Process, which is an extracting and purifying process developed by Ludwig Mond in 1899.

Resin-in-pulp method for recovery of nickel and

Nickel and/or cobalt can be recovered in substantially pure form from the eluate by known processes. The metal-depleted slurry proceeds to waste treatment and disposal. This process eliminates the ditfficult solid/liquid separation, which could otherwise be required to recover metals values from the pregnant leach slurry.

Stainless steel The role of nickel Nickel Institute

Most nickel-containing materials are fully recyclable at the end of the product's useful life; indeed their high value encourages recycling. This, in turn, lessens the environmental impact of nickel-containing stainless steels by reducing both the need for materials and the energy that their production uses. For example, the amount of stainless steel scrap currently being used
