桥口铅锌矿是由小到大、由土到洋发展起来的中型有色金属矿山,矿产品总产值由建矿初期的50.8万元发展到1983年的568万元,增长了11.5倍,截止1983年底止累计工业总产值4904.5万元,上缴利润1480.4万元,为国家投资的12倍。随着400吨/日采选综合生产能力的建成投产,可年产铅锌金属量5000～6000吨,工业总产值可达800～900万元,实现利税300万元。
Qiaokou lead-zinc mine is a medium-sized non-ferrous metal mine developed from small to large and from earth to ocean. The total output value of mineral products has grown from 508,000 yuan in the early stage of construction to 5.68 million yuan in 1983, an increase of 11.5 times. By the end of 1983, it had accumulated a total industrial output value of 49.0445 million yuan and turned over a profit of 14.880 million yuan, 12 times of the national investment. With the completion of the comprehensive production capacity of 400 tons / day, the annual output of lead and zinc will be 5000-6000 tons, the total industrial output will reach 800-9 million yuan and the profit and tax will reach 3 million yuan.
