    The smelting of gold began sometime around 6000 - 3000 BC. According to one source the technique began to be in use in Mesopotamia or Syria. In ancient Greece, Heraclitus wrote on the subject. According to de Lecerda and Salomons (1997) mercury was first in use for extraction at about 1000 BC, according to Meech and others (1998), mercury was used in obtaining gold until the latter period of the first millennia.

    Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms ...

  • Gold extraction - QueensMineDesignWiki

    For most free-milling ores, a pretreatment process is necessary when chemical recovery is being employed. The gold is not sufficiently liberated as is the case with placer ores, and therefore crushing and grinding is required to allow the cyanide to access gold components. Permeability is the major indicator of how much communition is required prior to leaching. Although there are various ...
