在社会主义建設总路綫的光輝照耀下,1958年內有色金屬选矿工業有着很大躍进,选矿企業的生产技术水平較过去有显著提高。首先以选矿回收率为例: 1958年各單位的选矿回收率普遍都有很大提高,尤其以銅和鎢的选矿厂提高最多。在銅系統中选矿回收率达到90％以上的已有6个单位,在鎢系統中选矿回收率达到80％以上的已有11个單位。其中石嘴子在1958年內最高一月的选矿回收率曾达到98.17％,銅官山最高一月曾达到97.77％,浒坑最高一月曾达到92.08％。其次,各选矿厂的处理量普遍都有很大增長。如中南某鉛鋅选矿厂年初时日处理量560吨,到第四季度就达到日处理量1200吨,提高
Under the glorious shining of the general line of socialist construction, there was a great leap forward in the nonferrous metal beneficiation industry in 1958, and the technological level of mineral processing enterprises was significantly raised over the past. First of all, take the dressing recovery rate as an example: In 1958, the dressing recovery rates of all units generally have greatly increased, especially with copper and tungsten concentrator to increase the most. In the copper system beneficiation recovery rate of 90% or more have been six units in the tungsten system beneficiation recovery rate of 80% or more have been 11 units. Among them, Shouzui had the highest mineral recovery rate of 98.17% in January of 1958, 97.77% of Tongguan Mountain in January and 92.08% of the highest point in January. Second, the throughput of various concentrator plants generally have greatly increased. Such as a lead-zinc concentrator in South China at the beginning of the amount of 560 tons at the beginning of the fourth quarter to reach the daily handling capacity of 1,200 tons, increased
