Refining (metallurgy)
In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgical and hydrometallurgical techniques.

Electrolytic Refining and Winning of Metals SpringerLink
Abstract. In electrolytic refining, the plates of crude metal are anodically dissolved in a suitable electrolyte, while “pure” metal is deposited on the adjacent cathodes. The electrorefining process was introduced about a hundred years ago to produce a substitute to fire-refined copper.According to the subject method of refining a ferrous ion-containing acid solution, a metal selected from a group including Al, Cr, V, B, and Zn or an acid solution of that metal is added to a ferrous ion-containing acid solution, such as an acid solution which remains after steel is washed with an acid. The pH value of the acid solution is controlled to be within the US4889697A Method of refining ferrous ion-containing acid

CA1337504C Method of refining ferrous ion-containing acid
According to the subject method of refining a ferrous ion-containing acid solution, a metal selected from a group including A?, Cr, V, B, and Zn or an acid solution of that metal is added to a ferrous ion-containing acid solution, such as an acid solution which remains after steel is washed with an acid. The pH value of the acid solution is controlled to be within A ferro-alloy, namely ferrochrome or ferromanganese, is refined by being heated to at least 100° C above its melting point to form a bath whereupon oxygen is blown into the melt, below the bath surface, within a protective gas envelope. The rate of oxygen blowing is so chosen that 1% of carbon is oxidized within a period not to exceed about ten minutes, US4139370A Method of refining ferro-alloys Google Patents

3 Methods of Nonferrous Metal Recycling emew Corporation
However, recycling non-ferrous metals can be a problematic task as they will not always come in their pure form. Oftentimes, they are found in all sorts of liquid and solid mixtures from which they need to be extracted and purified before further use. Three methods used today for non-ferrous metal recycling are electrowinning, precipitationAccording to the subject method of refining a ferrous ion-containing acid solution, a metal selected from a group including Al, Cr, V, B, and Zn or an acid solution of that metal is added to a ferrous ion-containing acid solution, such as an acid solution which remains after steel is washed with an acid.

Continuous electrolytic refining process of cathode copper with
A blister copper anode plate, which contains 99.0–99.5% copper, is dissolute during the electrolytic refining process of copper in the CuSO 4 –H 2 SO 4 electrolyte system. Dissolution reactions of metals such as Fe, Ni, Pb, As, and Sb, and precipitation reactions of Au and Ag occur on the anode. As the concentration of Cu 2+ Production method of electrolytic iron. Smelting is typically classified into two procedures: the wet process and the dry process. Electrolytic iron is considered the “wet process” since electrolysis requires electric charges to move through a liquid solution. This action causes a chemical reaction called electrolytic refining.Electrolytic iron
