RECOVERY METHOD OF HIGH-GRADE TIN CONCENTRATE BY FROTH FLOTATION

摘要

The present invention provides a recovery method of a high-grade tin concentrate by froth floatation comprising: a first step of crushing an ore collected from an ore deposit; a second step of homogenizing granularity of the crushed ore to below 150 mesh by grinding the crushed ore; a third step of adding a reagent into the homogenized ore, agitating the homogenized ore by adjusting pulp density of the homogenized ore, and yielding a rougher concentrate by roughing floatation; and a fourth step of recovering a tin concentrate by performing cleaning floatation of the rougher concentrate, thereby recovering a tin concentrate with optimum class and a recovery rate from a tin ore produced in a domestic deposit.
