The Ore Dressing of Tin-polymetailic Sulfide Ores

摘要

The ore dressing of tin-polymetallic lean ores is a difficult problem and the research emphasis in domestic nonferrous metals mining field. Through research and tackle key problem, and in order to supply reference in dealing with the same types ores, this paper expatiates the exploiture and application of six item new technology and technics in ore dressing of tin-polymetallic lean ores. It include the technics of multi-step compounding disposing tailings, grinding step by step, grinding and processing circularly technology, high thickness without circle flotation technology, dispersedly flotation tin step by step technology, exceed fine lean plumhnm stibium zinc flocculation flotation technology, the synthetically recovery of waste water after ore dressing technology.
