湖南钨矿资源丰富,生产历史悠久。钨精矿产量居全国总产量的第二位,是我国重要的出口物资。近几年来,在钨精矿滞销,部分矿山地质储量出现危机,出矿品位逐年下降的情况下,选矿生产能力比历史平均水平提高7.8％,钨精矿产量比历史平均水平提高2.7％,上缴利税比历史平均水平提高10.35％,经济效益比较好。但1983年与1981年相比,利税率反而下降50％,尚有个别企业由于储量危机出现了亏损。因此,采取切实可行的措施,改变当前状况、为国家积累资金,是我省各钨矿企业和科研单位面临的一项迫切任务。本文探讨我省钨矿企业在不增加新的生产能力条件下,使矿山增产增收,进一步提高经济效益。
Hunan tungsten is rich in resources and has a long history of production. Tungsten concentrate output ranking second in the country’s total output, is China’s important export materials. In recent years, with the slow-down of tungsten concentrates and the crisis of some mine geological reserves and the drop of ore grade year by year, the beneficiation production capacity has increased by 7.8% over the historical average and the output of tungsten concentrates has increased 2.7% over the historical average. The profits and taxes increased by 10.35% over the historical average, with good economic returns. However, in 1983 compared with 1981, the profit and tax rate actually dropped by 50%, while some enterprises suffered losses due to the reserve crisis. Therefore, taking practical measures to change the current situation and accumulate funds for the country is an urgent task faced by various tungsten enterprises and research institutes in our province. This paper discusses the province’s tungsten ore enterprises without increasing the new production capacity, the mine increased production and income, and further improve economic efficiency.
