摘要
采用HN3·H2O-NH4Cl体系,在氧化剂(NH4)2S2O8存在下,可在较低的温度下进行黄铜矿的浸取。在选定的条件下,一次浸取可浸出25%~30%的铜。一般四次浸取,即可浸取完全。
In NH3·H2O-NH4Cl system, copper in the brassil can be leached outunder conditions of oxidant (NH4)2S2O8 and lower temperature.25 to 30 percent of coppercan be leached out from the brassil each time in the optimal conditions,and the copper canbe leached out to be at an end by four times leaching.
