The use of the terms extraction beneficiation and mineral processing in the Profile section of this document is not intended to classify any waste streams for the purposes of regulatory interpretation or application Rather these terms are used in the context of common industry terminology

Alfa Laval has a range of equipment to optimize key processes such as separation and heating and cooling in the beneficiation leaching and extraction of precious mineral ores including gold platinum and silver Our solidliquid separation can be used in various process steps

Mineral processing mineral beneficiation or upgradation involves handling three primary types of ROM material which have been blasted fragmented and brought out from an in situ position These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods

The two gold refining methods most commonly employed to derive pure gold are the Miller process and the Wohlwill process The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold

There are three general methods of contacting ores with leach solutions 1 heap leaching 2 vat leaching and 3 agitation leaching Cyanidation heap leaching and vat leaching account for most gold and silver recovery8 These leaching methods are discussed in detail below 1 Cyanidation

New methods of explosive tailoring and timing would also have significant benefits Ore sorting in mining is usually considered a preconcentration method of upgrading runofmine ore before another beneficiation process Ore sorting is a dry process primarily used for very coarse particles in heaps to leach copper from secondary copper

They estimated that over the fiftyyear period 1930–1980 only 025 percent of the total land area of the United States was used for surface mining disposal of wastes from surface and underground mines and disposal of wastes from mineral beneficiation and further processing
