摘要
Abstract
A molybdenum ore belongs to easy-recovery molybdenum sulfide,which is associated with a small a-mount of chalcopyrite.In order to make full and efficient use of the molybdenum resource,the key experimental studies on the grinding fineness of roughing,the pH of flotation,the type and dosage of collector,the type and dos-age of foaming agent,the regrinding fineness of cleaning and the type and dosage of copper depressant for copper-molybdenum separation were systematically carried out.The test results show that the process flow of one roughing-two scavenging-one pre-cleaning-two cleaning scavenging-seven cleaning is adopted,when the dosage of pH reg-ulator lime is 300 g/t,the dosage of molybdenum collector diesel is 142 g/t,the dosage of foaming agent 2# oil is 52 g/t,the dosage of sodium silicate is 50 g/t,and the dosage of copper depressant BK505C is 260 g/t,a molyb-denum concentrate with the concentrate grade of 54.45% and the recovery rate of 95.58% can be obtained.关键词
