After oil, grease, and other organic contaminants are removed from the surface of steel in a degreasing tank, there still remains a thin layer of iron oxide (mill scale) adhered to the steel. In a galvanizing plant, steel will be pickled in an acid tank after the degreasing operation and before pre-fluxing.

Shah, 1998 also reported a plant for the production of zinc following SX–EW process. In this plant zinc ash is leached with sulphuric acid without calcination to produce leach liquor containing 10 g/l Zn with 95% recovery. Iron is precipitated by oxidizing ferrous ions to ferric iron with MnO 2 or chlorine gas. Zinc from the leach solution is ...

Abstract The state of the art for the recovery of metals from steel industry by-products using hydrometallurgical processes is reviewed. The steel by-products are different slags, dusts, and sludges from a blast furnace (BF), basic oxygen furnace (BOF), electric arc furnace (EAF), and sinter plant, as well as oily mill scale and pickling sludge. The review …

The grinding process for zircon commonly involves wet or dry methods. In the wet process, rotary cylinder ball mills, stirring mills, or sand mills are typically used. Today, larger-scale zircon processing plants mostly employ wet ball mills or stirred mills when the product size requirements are d50 <1.2μm and d97 ≤3μm.
