DOI: 10.1016/j.mineng.2021.106929
Abstract: Abstract A small non-toxic compound dithiothreitol (DTT) was introduced as an environmental-friendly chalcopyrite depressant in Cu-Mo flotation separation. The separation performances were studied via flotation tests. The adsorption mechanism was explored by contact angle, Zeta… read more here.
