摘要： Process for recovering copper sulphide and optionally molybdenum sulphide from a copper bearing ore by froth flotation includes crushing said ore, mixing the obtained ground powder with at least a collector and water, aerating the slurry, and removing and concentrating the mineral froth formed at the surface of the bath, wherein the collector comprises a thioglycolic acid derivate having the following formula: wherein R1 is N or O, and R2 is an alkyl group having 2 to 12 carbon atoms.

摘要翻译： 通过泡沫浮选从含铜矿石中回收硫化铜和任选的硫化钼的方法包括粉碎所述矿石，将获得的粉末粉末与至少一种收集器和水混合，对浆料进行充气，以及去除和浓缩在表面形成的矿物泡沫 的浴，其中收集器包含具有下式的巯基乙酸衍生物：其中R 1是N或O，并且R 2是具有2至12个碳原子的烷基。
