Common Nickel Processing Methods - Xinhai

2020-4-24  The nickel processing methods are as follows: 1. Direct (or parts) preferential flotation method. This nickel processing method is the copper concentrate alone, used in the case of high copper content. The main characteristic of this nickel processing method is that the copper concentrate with low nickel content can be obtained directly. 2.

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.
