浮选是把磨细后的有价矿物与伴生脉石分离的重要工业生产方法。浮选系统包括浮选设备,化学药剂和浮选作业。本文专题讨论浮选用的化学药剂,如捕收剂、起泡剂、活化剂、抑制剂和pH剂等。文中给出了铜硫化物(主要是黄铜矿,脉石可以是各种各样的,如石英石、方解石、黄铁矿、磁铁矿和白云石)的实验室和工业生产浮选试验数据。 Flotation is an important method of industrial production that separates finely-milled valuable minerals from associated gangue. Flotation systems include flotation equipment, chemicals and flotation operations. This article focuses on flotation chemicals such as collectors, foamers, activators, inhibitors and pH agents. The laboratory and industrial production flotation tests for copper sulphides (mainly chalcopyrite, gangue can be varied, such as quartz, calcite, pyrite, magnetite and dolomite) are given data.
