EXTRACTION OF HIGH QUALITY TALC FROM TALC ... - core.ac.uk

It was found that talc can be separated as float at pH 6 - 7±0.2 in rougher flotation and 10 - 11±0.2 in cleaning flotation, depressant dosage 0.10kg/ton, and collector dosage of 1.2 kg/ton. Talc concentrate at recovery of about 60 - 70% with a grade of 92.50% from an ore containing about 50 to 70% talc was obtained. PDF Removal of impurities from talc ore by leaching methodThe talc sample used in this study contained 70% talc, 15% lizardite and 10% kaolinite, following the removal of carbonate minerals by HCl leaching as a pre-concentration step.
