Occurrence mechanism of silicate and aluminosilicate minerals in Sarcheshmeh copper flotation concentrateH.R.Barkhordari11,E.Jorjani11,M.Noaparast31. Mining Engineering Department,Science...="ChDivSummary">The Sarcheshmeh copper flotation circuit is producing 5×104 t copper concentrate per month with an averaging grade of 28% Cu in rougher,cleaner and recleaner stages.In recent years......
, Changsha 410083, China) Absract: In order to solve the problem that fine serpentine deteriorates the flotation of sulfide copper ore in Chengde,the effect and mechanism of frothers on fine serpentine were studied. The effects of variety and dosage of frother,surface tension,foam stability on the floatability of fine serpentine were investigated by flotation tests, and the measurement of surface......
