Error in applications
I´m pretty sure thiophosphate is used to depress copper sulfides and not molibdenite, as it is part of the copper-molybdenum separation step in froth flotation. It keeps copper, iron and some other metals down in the cell so the molybdenum floats off. Maybe it's just wording, In this context, the Nokes reagent is called a "depressant," since it suppresses the flotation tendency of the solids.[3] doesn´t mention if the solids are the molibdenite or the rest of them.
