我矿是1966年筹建的日处理量50吨铅锌矿石的采选企业。到1977年止,连年亏损为总投资的120％。通过挖、革、改,1978年第一次实现利润12万元,1980年实现利润34.6万元,1981年增加到56万元。我们的具体做法是: (一)扩大选矿厂处理能力 1971年,虽然形成了日处理100吨的选矿生产能力,但东矿体采矿能力满足不了选矿生产。1972年,根据矿体资源情
I mine in 1966 to build the daily handling capacity of 50 tons of lead-zinc ore mining enterprises. Until 1977, the annual loss of 120% of the total investment. Through digging, leather and reform, the first profit in 1978 was 120,000 yuan, a profit of 346,000 yuan in 1980 and an increase of 560,000 yuan in 1981. Our specific approach is: (A) to expand the processing power plant In 1971, although the formation of daily processing capacity of 100 tons of mineral processing, but the East ore mining capacity can not meet the beneficiation production. In 1972, according to the situation of ore resources
