为了深入贯彻国民经济调整方针,国务院今年提出,对现有企业进行技术改造,是发展经济的战略措施.某金矿选厂,早在一九六○年改为土洋结合生产,即采用单一摇床加渗滤氰化工艺流程,生产指标不高,金属流失较大.据一九八○年生产统计,黄金回收率仅在65%左右.生产指标之所以不高,主要原因是现场生产流程不够完善,与矿石性质不相适应.从国内外黄金发展来看,采用单一重选手段,很难从矿石中完全回收金,尤其是对细粒金的回收应采用浮选,搅拌氰化等工艺才能适应.尽管现场对摇床的中、尾矿采取了渗滤氰化,但由于其方法本身的弱点,远不能达到理想的指标,所以这种流程结构不尽合理,流程单一、加之生产管理薄弱等等,都是造成生产指标低下的主要原因.
In order to thoroughly implement the principle of national economic readjustment, the State Council proposed this year that technological transformation of existing enterprises is a strategic measure for economic development. A gold-mining plant was replaced by a combination of indigenous and marine products as early as 1960 According to 1980 production statistics, gold recovery rate of only about 65%. The reason why the production index is not high, mainly due to on-site production The process is not perfect enough, and the nature of the ore does not match.From the domestic and international gold development point of view, the use of a single re-election means it is difficult to completely recover gold from the ore, especially for the recovery of fine gold flotation should be used, And other processes to adapt.Although the site on the shaker, tailings taken percolation cyanide, but because of its own weaknesses, far from being able to achieve the desired indicators, so the process structure is not reasonable, a single process, coupled with Weak production management, etc., are the main reasons for the low production index.
