Features of Processing Tin-Bearing Tailings at the Solnechny Mining and Processing Plant

Flotation extraction of tin from tailings of sulfide-tin ore dressing using thermomorphic polymer

“…Before the main tin flotation, the non-magnetic product was activated with copper sulfate (CuSO 4 consumption was 200 g/t). Pretreatment of cassiterite with copper sulfate activates the mineral flotation and increases the amount of the collecting reagent fixed on it [11,16]. Flotation studies conducted earlier on cassiterite using a thermomorphic polymer and preliminary CuSO 4 activation of the mineral has showed that the mineral yield increases to 87%, which is 26% higher than that without preliminary activation [11].…”
