在铜矿物相分析中,一般只分析铜的氧化物(包括硫酸盐、碳酸盐、氧化物及硅酸盐等),次生硫化物(包括铜蓝、辉铜矿及斑铜矿等),和原生硫化物(包括黄铜矿、方黄铜矿)。基本上已能满足生产上的要求。其中氧化矿的浸出是用5%H_2(?)O_4为浸取剂,在一般情况下均能普遍适用。而关于作氰化钾溶液浸出次生硫化铜这方法从质量上来讲也是能满足要求的,但氰化钾为一剧毒之化学试剂,应尽可能避免使用,况且当浸取过程结束以后,在定量步骤上也产生繁复而危险的过程,在破坏氰化钾时将产生剧毒之氰化氢气体等,这
In copper mineral phase analysis, only copper oxides (including sulfates, carbonates, oxides and silicates, etc.), secondary sulfides (including copper blue, chalcocite and bornite, etc.) ), And primary sulfides (including chalcopyrite, chalcopyrite). Basically able to meet the production requirements. The leaching of the oxide ore is 5% H 2 O 4 as leaching agent, which can be generally applied under normal circumstances. However, the method of leaching secondary copper sulfide as a solution of potassium cyanide is also satisfactory in terms of quality, but potassium cyanide is a highly toxic chemical reagent and should be avoided as much as possible. Moreover, when the leaching process is over, In the quantitative steps also produce a complex and dangerous process, in the destruction of potassium cyanide will produce toxic hydrogen cyanide gas, etc., which
