Environmental desulfurization using non-selective flotation has recently been implemented as an integrated management approach for mine tailings. Furthermore, physical separation techniques, commonly used in mineral processing and offering a remarkable potential for sulfur and valuable minerals enrichment, are rarely used to manage mine wastes.

The material, pulped after fragmentation through a wet process, generally measuring less than 250 µm, allowing the liberation of the recoverable mineral from the gangue, is conditioned by the addition of a chemical reagent called a collector, whose role is to selectively render hydrophobic the surface of the mineral to be floated.

It is an underwater mineral separation system and method, which extracts sediments from the aquatic bed of any sea, ocean, reservoir or river; and then separates said minerals by gravitation or difference in density; and immediately deposits the gangue on the water bed; These minerals are then moved to a storage location. It consists of an arrangement of elements that function …

Gravimetric separation is a process widely used in the metallurgical industry since it takes advantage of the difference in weights in the matrix of a mineral. One of the most common pieces of equipment to carry out this process is the table, for which there are mathematical models that allow saving time and resources.
