This invention relates to the removal of iron which is contained as an impurity in the ferrous state in aqueous solutions of chemicals, as in the manufacture of zinc sulfate and zinc chloride. In the manufacture of zinc salts the crude liquors contain varying amounts of ferrous iron, depending upon the source of the raw materials and the particular methods of operation.
1/2/2006 The content of iron in zinc sulfide concentrates is essential for the process of zinc production . This content is typically in the range 3-18% ,but if it exceeds 8% , about 10% of
THIS SPECIFICATION DISCLOSES A PROCESS FOR REMOVING IRON COMPOUNDS FROM A ZINC CHLORIDE SOLUTION CONTAINING DISSOLVED THEREIN SMALL QUANTITIES OF ORGANIC MATTER BY FIRST CONTACTING THE SOLUTION OF...
A process for removing iron and manganese from solutions of zinc chloride containing hydrochloric acid, having a zinc ion concentration between 50 and 500 g/l, an iron ions concentration between 1 and 70 g/l, and a manganese concentration between 10 andFe 2
Efficient separation of zinc and iron is an ideal idea for avoiding iron residues by control zinc and iron phase from ZLR. In this study, a novel process for separating zinc and iron present in ZLR is developed consisting of sulfates roasting and selective leaching. The extraction of zinc increased to 92.63% while iron decreased to 2.04%.
