高剪切搅拌调浆对细粒级黄铁矿的浮选强化研究
Flotation Strengthening of Fine-Grained Pyrite by High-Shear Stirring and Slurry
摘要
Abstract
Combined with the strengthening theory of fine particle flotation process,taking fine-grained pyrite in the tailings of Wushan Copper Mine of Jiangxi Copper Co.,Ltd.as the research object,the internal flow field characteristics of conventional conditioning stirred tank and high shear modifier were qualitatively compared and analyzed by computational fluid dynamics simulation method,and at the same time,semi-industrial-scale conditioning and pulp flotation experiments were carried out,and the influence of different mix-ing methods and grout intensity on fine-grained pyrite flotation was studied.The results indicate a high dissipation rate of turbulent ki-netic energy and a more uniform distribution,which effectively activates and modifies the fine-grade pyrite in Wushan Copper mine.Compared to conventional stirring buckets,the sulfur recovery rate can be increased by 9.76 percentage points.Furthermore,an en-hanced stirring intensity significantly improves the sulfur recovery,particularly for recovering fine-grade sulfur.关键词
