由江西冶金学院、江西下垅钨矿研制的CGX-Ⅰ型磁-光分选机鉴定会于1982年11月10日至12日在下垅钨矿召开.会议由江西冶金厅主持.1978年6月制出第一台工业样机并于同年7月纳入下垅钨矿大平选厂生产流程,处理20～30毫米的矿石.经长期运转表明,脉石选出率80%.块钨选出率62%,废石丢弃率81.7%,处理量500～800公斤/小时.该机的主要特点是在一台设备上联合采用磁-光两种检测探头,可同时进行黑白分选和磁性与非磁性
The CGX-Ⅰ magneto-optical sorting machine developed by Jiangxi Metallurgy Institute and Jiangxi Xiandao Tungsten Mine was appraised at Xialiu Tungsten Mine from November 10 to November 12, 1982. The meeting was presided over by Jiangxi Metallurgical Department. The first industrial prototype was produced in the same month and was included in the production process of the Daping Tungsten Factory in Shimonosechi in July of the same year to treat 20-30 mm ores. The long-term operation showed that the gangue selection rate was 80% 62%, discard rate of waste rock 81.7%, processing capacity 500 ~ 800 kg / h.The main features of the machine is the combination of magnetic - light two detection probe on a device, can be simultaneously black and white sorting and magnetic and non magnetic
