Sodium Hydrosulfide (NaSH)An Alternative to Sulfur

The process feeds the Cu Sulfide concentrate produced through flotation and applies a reverse flotation circuit to separate the Moly sulfide from Copper sulfides. In this case, the MoS floats and the CuS is depressed in a bank of flotation cells. The control devise is also an ORP meter typically controlled at between 450 mv and 500 mv.

Flotation Froth an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

Copper Mining and Extraction Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide removes some of the sulfur as sulfur dioxide This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.
