1958年大躍进中,我矿的生产任务经过多次修改,确定要鼓足干勁,力爭上游,产量比1957年翻一番。当时的情况是采矿問題不大,全矿能不能躍进关鍵就在于选矿。选矿的躍进最好的办法是:挖掘設备潛力、修改流程提高处理能力。在矿党委的正确領导下由于全体职工的努力,在原基础上用少量資金和最短的时间完成了扩建,使选矿日处理量提高为原来的300％,从而一个选矿厂起到了三个选矿厂的作用。这次扩建总投資额仅67,000元左右,停止生产 During the Great Leap Forward in 1958, the mine production task was revised many times to determine that we should work hard and strive to reach the upper reaches with a doubling of output than in 1957. At that time the situation is not mining problem, whether the whole mine can leap forward lies in mineral processing. The best leaching process beneficiation is: mining equipment potential, modify the process to improve processing power. Under the correct leadership of the mine party committee, due to the efforts of all the staff and workers, the expansion was completed on the original foundation with a small amount of funds and the shortest time so that the daily processing capacity of the beneficiation plant could be raised to 300% of the original, so that one concentrator played three beneficiation plants Role. The total investment for this expansion is only about 67,000 yuan, to stop production
