云南省金属学会选矿学术委员会于1981年9月23日至27日在大姚铜矿召开铜选矿学术讨论会.参加会议的有省内外二十五个单位的专家、教授和工程技术人员共88人.会议期间收到了中国金属学会选矿学术委员会等单位发来的贺电. 云南铜矿石储量极为丰富,全省有大小铜选厂十多个,铜的选矿技术指标在76年前实收率为83%,精矿品位14%.目前达到了实收率85%,精矿品位20%的指标,但距冶金部的要求还有一定的差距,与会同志针对云南铜选矿在调整时期如何进行挖、革、改,提高实收率和精矿品位,降低消耗等问题,按照“双百”方针,采取大小会议结合的
The Yunnan Metals Society Mineral Processing Academic Committee convened a copper mineralization seminar at Dayao Copper Mine from September 23 to September 27, 1981. A total of 88 experts, professors and engineers from 25 provincial and municipal units attended the conference During the meeting, he received a congratulatory telegram from the China Metals Association, such as the Academic Committee for Mineral Processing, etc. Yunnan’s copper ore reserves are extremely rich. There are over 10 copper processing plants in the province. The copper beneficiation technical indicators were 76 years ago 83%, concentrate grade 14% .At present, the actual yield 85%, concentrate grade 20% indicators, but there is still a certain gap between the requirements of the Ministry of Metallurgy, participants at the Yunnan copper dressing in the adjustment period how to proceed Digging, leather, change, improve real yield and concentrate grade, reduce consumption and other issues, in accordance with the “double hundred” approach to the size of the meeting combined
