本文根据试验结果和生产实践,阐述了采用选矿冶金联合工艺分离锡石——多金属硫化矿粗锡精矿中锡钨铋硫矿物的过程。论述了多种有用矿物致密共生的矿石采用选矿冶金联合工艺的必要性和重要性,证实了选矿冶金联合工艺是有效分离上述矿石的各种矿物的有效方法。 Based on the experimental results and production practices, this paper describes the process of separation of tin, tungsten, bismuth and sulfur minerals from the cassiterite-polymetallic sulphide ore crude tin concentrate by the combination of beneficiation and metallurgy. This paper discusses the necessity and importance of the ore - dressing metallurgy combined process for a variety of useful minerals, and proves that the beneficiation and metallurgy combined process is an effective method for effectively separating the various minerals from the ore.
