几年来,有色金属鑛石的选鑛工作,在党的正确领导和苏联专家的帮助下,由于生产和研究部门全体职工的创造性劳动,在提高处理鑛量、改进产品质量和实行原料综合利用、特别是提高金属回收率的工作上都做了很大的努力,取得了进步,而更重要的是打破了过去认为选鑛回收率很难再加提高的保守思想。实际经验证明:只要彻底开展研究工作,及时推广先进经验,不但机械化选厂,就是人工洗选厂和锡砂溝,回收率也能大大提高。但是,与此同时,由于我们对于各项先进经验还不能及时
In recent years, with the correct leadership of the party and the help of Soviet experts, due to the creative work of all the staff and workers in the production and research departments, the beneficiation of nonferrous metal ores has been improving ore handling capacity, improving product quality and implementing the comprehensive utilization of raw materials. In particular, great efforts have been made to improve the metal recovery rate and progress has been made. More importantly, it has smashed the conservative thinking that ore dressing recovery rates were difficult to increase in the past. The actual experience shows that as long as the thorough research work and timely promotion of advanced experience are carried out, not only mechanized dressing plants but also artificial washing plants and tin sand ditches can greatly enhance the recovery rate. However, at the same time, because we are not yet able to provide timely and advanced experience
