Weak acid mine pulp made of lime from Sulfur dioxide Also can use Sodium thiosulfate, sodium metabisulfite to replace sulfite, to inhibit sphalerite and iron pyrites (commonly known as FeS2). Maybe you are interested in Sodium Metabisulfite High Purity. Product Show. Sodium Metabisulfite for
Sodium Metabisulfite aka MBS is used for pH control in froth flotation to control Pyrite depression. Below is a graph showing pH VS pyrite recovery at various collector addition rates. It is also used to prevent flotation of sphalerite by copper activation in the presence of Tennantite/Covellite in the ore. For pyrite flotation, you see maximum iron/pyrite depression using Sodium Metabisulfite
