Abstract: Jarosite residue is a solid waste originating from iron removal process of zinc hydrometallurgy,containing a certain amount of Fe and other valuable metals.In order to recovery Fe,the rotary hearth furnace direct reduction-melting process had been developed to process carbon-containing pellets of jarosite residue.The effect of the process parameters on Fe recovery from jarosite residue was studied,through direct reduction of natural basicity carbon-containing pellets of jarosite residue.At the same time,the pilot plant test has been carried out with rotary hearth furnace.The optimum conditions from experimental test are as follows:reduction temperature of 1 100℃,reduction time of 30 min,C/O=1.2.Under these conditions,the metallization rate of carbon-containing pellets of jarosite residue reaches 90.6%,the metallization rate of pilot plant test is 75%,the comprehensive recovery rate of iron is 85%.
