一、概述 1969年,我国黑钨矿山开始使用光电选矿机,十多年来光选机的发展十分迅速,特别是近二、三年来有比较大的进展。机型增多,有江西有色冶金研究所研制的GS—IA型、GS—IB型、GS—Ⅱ型、GS一Ⅲ型,江西冶金学院研制的CGX—Ⅰ型、大吉山钨矿研制的B—650—Ⅰ型,瑶冈仙钨矿研制的YG—40型:处理量增大,平皮带光选机的处理能力是早期光选机的8～12倍;分选指标提高,脉石选出率由70％提高到
I. Overview In 1969, China’s tungsten mine started to use photoelectric concentrator, the development of light separator for more than a decade has been very rapid, especially in the past two or three years have made great progress. There are more models, such as GS-IA, GS-IB, GS-Ⅱ and GS-Ⅲ developed by Jiangxi Nonferrous Metallurgy Research Institute, CGX-Ⅰ developed by Jiangxi Institute of Metallurgy and B- 650-Ⅰ type, YaoGangXiang cemented tungsten developed YG-40 type: processing capacity increases, the flat belt light sorting machine processing capacity is 8 to 12 times the early light machine; sorting index increased, gangue selected The rate increased from 70% to
