How to Extract Nickel From Copper-Nickel Sulfide Ore? - Mining-pedia

1. Differential flotation or partial differential flotation process. When the content of copper is much more than nickel in the ore, this process can be used to separate the copper as the single concentrate. The advantage of this process is that the copper concentrate with lower nickel content can be obtained directly. 2. Bulk flotation process.

There are several reasons as to why an ore may be refractory. The two most common are: 1) The gold is locked in refractory sulphide minerals such as pyrite, arsenopyrite or pyrrhotite and occurs in both the chemically bonded state and as micro or nano-size grains of metallic gold. 2) Or the gold is locked in silica.
