| Abstract: | Beneficiation tests were conducted to process tin ore slime with fineness of -0.005 mm46.50%. Fine cassiterite was recovered using a flowsheet composed of selective flocculation desliming, flotation desulfurization and cassiterite flotation. With the tin ore slime grading 0.59% Sn, the above processing technique achieved 54.70% recovery into a tin concentrate grading 6.80% Sn (with a recovery rate of 80.41% for the whole tin flotation operation), which has also successfully applied into the commercial production. This study can provide a technical support for the efficient exploitation of this kind of resources. |
