Abstract
It has been studied the celestite and calcite flotation in a Hallimond thermostatted tube using sodiumdodecylsulphonate (SDS) as collector a nd quebracho as depressant. Experiments have been realized at 293 and 313 K, using pure minerals with a size between 117 and 149 mu m. The r esults obtained show that the existence of quebsacho has an important influence in calcite flotation, being the effect on celestite lower, m ainly at depressant concentrations lower than 0.12 g/L.
