is a promising method to recover nickel and cobalt metal, leaving leaching residue as a suitable iron resource. The phase transformation in reduction process with microwave heating was investigated by XRD and the reduction degree of iron was analyzed by chemical method. The results show that the laterite samples mixed with active carbon couple well with microwave and the temperature can reach approximate 1......

advantage of using microwave heating is that the shorter treatment time, which in many cases represents a reduction in the energy consumption as well. Recently, some studies focus on the application of microwaves for improving size reduction and mineral liberation[9-11]. After being pretreated by microwave heating, the leaching performance and leaching rate of raw materials can be improved......
