氧化铜矿如用浮选方法处理,不仅需要将矿石粉度磨成很细及药剂消耗量大,且金屬回收率較低。故对氧化铁、碳酸鹽类不多的氧化铜矿,采用湿法冶煉时,矿石破碎到相当大的粒度即可用酸浸或硫酸化焙燒方法进行处理。这一方法不但可以簡化生产过程、节約人力,而且还能徹底地回收其中所含的铜金屬,从而既能降低生产成本,又能迅速地促进銅产量的增長,这是符合党中央多、快、好省地办工業的方針的。 (一)酸浸 1.簡要过程 將氧化銅矿石破碎到5～15公厘或粉碎到0.074—0.3公厘,放入硫酸槽中浸析。如含有回收价值的黄金或硫化物时,最好先將黄金
Copper oxide ore, such as the use of flotation methods, not only need to finely ground ore ores and pharmaceutical consumption, and low metal recovery. Therefore, iron oxide, carbonate few copper oxide, the use of wet smelting, the ore crushed to a considerable size can be acid leaching or sulfated roasting method for processing. This method can not only simplify the production process and save manpower, but also completely recover the copper metal contained therein, thus not only reducing the production cost but also rapidly promoting the increase of the copper output. This is in line with the requirements of the CPC Central Committee, Quickly and economically do the industrial policy. (A) acid leaching 1. A brief process of copper oxide ore crushed to 5 to 15 mm or crushed to 0.074-0.3 mm, into the sulfuric acid tank leaching. Such as gold or sulfide containing recovery value, it is best to first gold
