南京钢铁厂某分厂从综合利用出发,用炼铁副产品——海绵铜生产CuSO_4。海绵铜由粗氯化铜经铁屑还原制得,故含有较高量的氯离子,约2%左右。CuSO_4的生产工艺为:海绵铜+10%H_2SO_4溶液配制成含Cu160克/升的料浆,送入反应釜,加热到85～90℃,通入空气进行氧化,同时搅拌溶液,溶液流动速度约2米/秒,反应2小时,溶液转入结晶槽中使CuSO_4结晶出来。
From a comprehensive utilization of a branch of Nanjing Iron and Steel Plant, CuSO_4 is produced from sponge copper, a byproduct of ironmaking. Sponge copper by the crude copper chloride reduction obtained by iron filings, it contains a high amount of chloride, about 2%. The production process of CuSO 4 is as follows: a sponge copper + 10% H 2 SO 4 solution is prepared into a slurry containing Cu 160 g / L into a reactor and heated to 85~90 ° C., aerated by air while stirring, and the solution flow rate is about 2 m / s, the reaction 2 hours, the solution into the crystallization tank CuSO_4 out.
