The product of this process was a white metal, known as finers metal or refined iron. Precious metals. Precious metal refining is the separation of precious metals from noblemetalliferous materials. Examples of these materials include used alysts, electronic assemblies, ores or metal alloys. Process
Generally speaking, extractive metallurgy is the process of the extraction of metals from ores, concentrates (enriched ores), scraps, and other sources and their refining to the state of either liquid metal before casting or to solid metals. The extraction and refining operations that are required may be carried out by various metallurgical

method of refining ferrous metal ore . method of refining ferrous metal ore china . method of refining ferrous metal ore Ancient iron production, the free encyclopedia it can help to control the supply of refining media to the melt. which were two common methods for smelting iron, more carbon reacted with iron ore,
The metals so extracted are further refined by suitable methods. The electrolytic method is the most suitable method for refining the nonferrous metals. The metals produced by any method given above are not very pure. These need further refining. This can be done by any of the following methods: Liquation method
Heavy and nonFe metals can be melted down, time after time. They are thus ideal for recycling. An important role here is played by the quality of the processed, sorted metals to ensure their use in the smelt and to achieve value creation and marketing assurance. Nonferrous metals find uses in all areas of industry and in consumer goods.
method of refining ferrous metal ore. method of refining ferrous metal ore. We hold "Pursuing the SCM Technology and Quality" as our management concept all the time. Refining (metallurgy) Wikipedia, the free encyclopedia. Refining (as in nonmetallurgical uses)
BACKGROUND OF THE INVENTION. The present invention relates to a method for recovering precious metals from metallurgical products such as ores, wastes and electrolytic slimes and, more particularly, to an improved fire refining precious metal assay method for these materials.
definition of electrolytic iron ore refining vilamaria . definition of electrolytic iron ore refining, method of refining ferrous metal ore Thismain aim of the smelting process is to convert metals from their.
Primary smelting and refining produces metals directly from ore concentrates, while secondary smelting and refining produces metals from scrap and process waste. Scrap includes bits and pieces of metal parts, bars, turnings, sheets and wire that are offspecifiion or wornout but are capable of being recycled (see the article "Metal
Electrorefining. Usually the object of electrolytic refining is to separate one metal in pure form from an alloy containing a high percentage of the desired metal, copper for instance, and a number of other metals dissolved in the copper or intimately mixed with it.

Once the ore is mined, the raw ore is firstly crushed and milled to expose auriferous minerals (mainly native metal). Before leaching, the grain size is prepared to 0.4mm, 74μm or 44μm depending on the leaching test result. In case the raw ore is highly oxidized or of too much slurry, hydrocyclone and thickener are used to remove slurry.
