瑶岗仙钨矿的工程技术人员,通过几年的努力,为我国研制成功了第一台工业型激光光电分选机(外型尺寸:长×宽×高=7000×1800×3200),于1981年12月7日正式投入生产,代替20～40毫米粒级人工手选。处理量5～10(吨/时)。通过10个月的生产试验,机器运行良好,经济效果显著,每吨废石生产成本为0.73元,比手选低0.33元。废石选出率达90.94％,比手选选出率高35％,废石丢弃品位WO_3为0.023％,比手选低0.012％(绝对值)。
Yao Gangxian tungsten ore engineering and technical personnel, through several years of efforts for the successful development of China’s first industrial-type laser optical sorting machine (Dimensions: length × width × height = 7000 × 1800 × 3200), at December 7, 1981 formally put into production, instead of 20 ~ 40 mm grain class manual selection. Processing capacity of 5 to 10 (tons / hour). After 10 months of production test, the machine runs well and the economic effect is remarkable. The production cost per ton of waste rock is 0.73 yuan, which is 0.33 yuan lower than that of the hand-picked ones. The selection rate of waste rock is 90.94%, which is 35% higher than that of hand selection. The rejection level of rock waste WO_3 is 0.023%, which is 0.012% (absolute value) lower than that of the hand selection.
