What is Mineral Processing

Mineral processing is the art and technology of treating ores from the mining areas in order to separate the valuable minerals from the waste rock. It includes processes to provide a more concentrated material for the procedures of the following extractive metallurgy. The two main processes to increase the concentration of minerals are leaching and flotation.

Pionera biopolymer depressants are added to the froth flotation process to maintain or produce hydrophilic surfaces on minerals so they will remain in the pulp rather than float with the froth. The biopolymers selectively depress gangue materials such as pyrite, clay, and talc through dispersion.  Biopolymers adsorb onto gangue minerals preferentially over valuable minerals. Once adsorbed, the biopolymer’s presence inhibits collector adsorption on the gangue and reduces the magnitude of the galvanic interactions between the sulfide minerals. 

The effectiveness of a collector depends on the surface properties of the value and gangue minerals. Usually, the collectors are optimised to adsorb strongly to the value mineral surface to render them hydrophobic. Clay, other sulfide minerals and oxidation processes can change these surface properties and reduce adsorption. Pionera biopolymers disperse these blocking minerals and can make the reagents more effective, resulting in higher recovery.

Ores and Minerals

Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material.
