Abstract
It has been studied the celestite and calcite flotation in a Hallimond thermostatted tube at 203 and 323 K, using Sodium Dodecylsulfonate (S DS) as collector and sodium silicate as depressant. Pure minerals with a size between 117 and 149 mu m have been used. The results obtained show that the existence of sodium silicate has similar influence on bo th minerals, although depressant effect on calcite is higher, in parti cular at high concentrations of seriously acid flotation agent and bat hs.
