Sodium sulphide, with a chemical formula of Na2S, is a vital industrial chemical that finds extensive applications in various industries. In particular, the 60% industrial grade sodium sulphide plays a crucial role in the field of ore flotation.During the flotation process, sodium sulfide is added as a depressant to selectively inhibit the flotation of certain minerals. It reacts with metal ions, forming metal sulfides that are less floatable, thus......
