1981年10月,国家有色金属总局在金堆城组织了金堆城钼矿床两岔梁矿石选矿技术鉴定会。会议一致通过了金堆城钼业公司、矿冶研究总院的“金堆城钼矿床两岔梁矿石提高钼精矿品位的研究与实践”的技术鉴定证书,金堆城钼业公司的“CHF-X14米~3充气机械搅拌式浮选机在选钼工艺中的应用”的技术评议书。提高精矿品位是在500(吨/日)选厂进行的,钼精矿品位由45%提至50%,回收率未降低;所采取的增加再磨细度(由-34微米占68%增至75%)、提高精选粗精矿品位(由2～3%提至5～6%)、粗精矿浓
In October 1981, the State Non-ferrous Metals Administration organized the appraisal of the technology of beneficiation of the two-beam steel ore in Jinduicheng molybdenum deposit in Jinduicheng. The meeting unanimously passed the technical appraisal certificate of “Jinduicheng molybdenum bed two-beam beam ore to improve research and practice of molybdenum concentrate grade” by Jinduicheng Molybdenum Company, Mining and Metallurgical Research Institute, CHF-X14 meters ~ 3 inflatable mechanical stirring flotation machine in the molybdenum technology application "technical evaluation. The increase in concentrates grade was carried out at a 500 (ton / day) mill. The grade of molybdenum concentrates was raised from 45% to 50% with no reduction in recovery rate. The increase in regrind fineness (from 68% Increase to 75%), improve the selection of coarse concentrate grade (from 2 to 3% to 5 to 6%), crude concentrate
