在湿法冶金过程中对溶液,矿浆的加热一般采用:蒸气直接或间接加热法;煤和焦煤的直接燃烧加热法;电加热等方法。在铅阳极泥选—冶联合工艺的工业试验中我们成功地应用了油加热法,对矿浆进行间接加热,使矿浆温度严格控制在80—90℃之间,保证了选冶过程中的水溶液氯化,酸浸,矿浆置换等工序的顺利进行,对整个工业试验创造了良好的条件 In the hydrometallurgical process of the solution, the slurry is generally used to heat: steam direct or indirect heating; coal and coking coal direct combustion heating; electric heating and other methods. In the lead anode mud election - metallurgical joint industrial test, we successfully applied the oil heating method, indirect heating of the pulp, the pulp temperature is strictly controlled at 80-90 ℃, to ensure that the process of selection and metallurgical process of chlorine Chemical, acid leaching, pulp replacement process smoothly, the entire industrial test to create a good condition
