Abstract:
Experiments on the beneficiation of multi metal pyritic sulphide ore of Copper - Lead - Zinc from Hindustan Zinc Limited, Udaipur (India) conducted using chemical auxiliaries based on guargum and its derivatives as depressant systems without any basic alteration in plant operating conditions, yielded better metallurgical results for recovery of copper values in flotation of copper concentrate. The silica depressants studied in present investigation, includes sodium silicate, guargum as well as its cationic derivative along with sodium isopropyl xananthate (IPX) as collector and methyl isobutyl Ketone (MIBK) as frother. The other operating parameters viz. reagent, concentration and pH of the pulp were also systematically studied and optimised. The Improved metallurgical results were obtained with combination of sodium silicate and cationic guargum as silica depressant at pH 10.5.
