    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
