摘要
用经650℃煅烧后的铜矿石与稀硫酸反应制备五水硫酸铜。考察了煅烧温度、硫酸浓度、反应时间和反应温度对浸出率的影响,实验结果表明当煅烧温度为650℃、硫酸浓度为30%、反应时间3h、反应温度40℃条件下,铜的浸出率达到98%以上。用本方法生产五水硫酸铜,具有原料易得、工艺简单、回收率高和产品纯度高等优点,具有实际生产价值。
The CuSO4· 5H2O is prepared from copper ore with watery sulfuric acid by calcination of 650℃. The effect of calcination temperature ,concentration of sulfuric acid ,react time and temperature on salvaged rate are investigated. The experiment results show ： when the calcination temperature is 650℃, concentration of sulfuric acid is 30%, react time is 3 hour and react temperature is 40℃, the salvaged rate of copper reaches 98%. The process is simple and has practical produce value, since the raw material is easy of access, the fraction recovery and the purity of product is high.
