Abstract
A process for the depression of iron sulphides and other disposable elements in the mineral concentration by flotation and electrochemical reactor. The proposed invention represents a method based on the action of electrodes on the mineral, which can replace, compliment or minimise the consumption of chemical reagents, as well as improving the effect thereof.
Claims15
A process for the depression of iron sulphides and other disposable elements in the flotation of mineral particles in liquid, which after the stages of extraction, crushing, grinding and suspension of the mineral in liquid, is characterised in that at least one sulphide is electrochemically depressed through the application of at least one electric potential.
An electrochemical reactor for the treatment of mineral pulp, with the aim to of depressing iron sulphides and other disposable elements in the flotation of mineral particles in liquid, characterised in that it comprises:
- At least one counter electrode (1),
- At least one working electrode (2),
- At least one electric source (3) and
- At least one connection between these three elements (4).
