摘要

The Cu-S flotation separation using a new organic depressant CTP has been worked out suc- cessfully in laboratory and on industrial scale in Dexin Copper Mime. The testing results showed that CTP is a new effective organic depressant of pyrite with good selectivity on Cu-S separation in low alkaline medium; copper indices of the new Cu-S separation process are Cu concentrate with a grade over 24/100 and Cu recovery above 97/100. The CTP dosage is about 45~50g/t, the lime dosage is greatly reduced from 5.14 kg/t to 1.30 kg/t as compared with the traditional reagent system; the recoveries of Au and Mo in the copper concentrate are increased by 1.6/100 and 23.88/100, respectively.
