本来一般用水法处理氧化銅矿,以硫酸来浸出提銅是最适用和最有效的方法。但根据其他厂矿的生产情况来看,这样銅的成本較高,更重要的是又由于前硫酸供应較困难,因此,我們根据原矿性質:孔雀石(CuCO_(?)Cu(OH)_2)藍銅矿(Cu_3[CO_3]_2[OH]_2),同时品位較低(0.5—1％),便采用了硫酸鹽化焙燒,开始是加硫磺混合焙燒,后来又由于硫磺的缺乏,供应不上成本太贵,所以我們对用黄铁矿(FeS_2)代硫磺(S)焙燒进行了大胆的試驗,經过試驗效果良好,現已正式用于生产。为了适应形势的發展,能够讓土法水冶銅的單位就地取材,因陋就簡地生产,現在把以黄铁矿代硫磺焙燒水治铜的方法簡單介紹如下: 配料
In general, the water treatment of copper oxide ore, copper sulfate leaching is the most suitable and most effective method. However, according to the production situation of other factories and mines, the cost of copper is higher, and more importantly, the supply of pre-sulfuric acid is more difficult. Therefore, according to the nature of the ore: malachite (CuCO_ (Cu) (OH) Copper (Cu_3 [CO_3] _2 [OH] _2), while the lower grade (0.5-1%), they use the sulfated roasting, the beginning is mixed with sulfur roasting, and later because of the lack of sulfur, the supply is not on The cost is too high, so we conducted a bold experiment on pyrite (FeS 2) generation of sulfur (S) roasting. After good test results, it has been formally used in production. In order to adapt to the development of the situation, it is possible to make the units of the indigenous plant for water and metallurgy come locally and simply produce for the sake of simplicity. Now the method of treating copper with pyrite roasting water on behalf of sulfur is briefly described as follows: Ingredients
