    The exploration and discovery of large, freemilling gold deposits in major mining districts has declined Mining companies face a difficult decision Do they process large, lowgrade deposits or look for smaller, often more complex ones in remote, often hardtoreach locations? To complicate matters further, these ore bodies are often refractory, where the gold is locked within sulphide· If we have to know about gold assay, it is important to mention the Fire Assay Process that has been employed in the mining industry for a long time Basically the ore is mixed with a mixture of fluxes and during the smelting process precious metals are liberated and most of heavy metals are trapped by the fluxes However, lead is the key element due to collect precious metals The latterGold Smelting & Refining ProcessGold bearing ores that include basemetal mineralization, particularly copper, are classified as complex ores These ores will often consume cyanide and create issues in CIP and elution Pregrobbing carbon is defined as the phenomenon whereby the gold cyanide complex is removed from solution by constituents of the ore (Rees & van Deventer, 2000) The presence of pregrobbing carbon ultimatelyGold extraction QueensMineDesignWiki

    · Ore is first crushed and then undergoes various processes depending on the nature of associated minerals Processing lowgrade ore is relatively simple while higher grades require more extensive processing Step #8 – Refining (offsite) Once basic processing is done, the ore is taken to a refinery where the remaining impurities are stripped out Crude gold is melted and treated withGold 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 stabilityThe colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstromsGold processing | BritannicaIt is particularly appropriate for low grade gold and silver ore processing (eg less than 5 ppm gold) but its use is not restricted to such ores There are many environmental hazards associated with this extraction method, largely due to the high acute toxicity of the cyanide compounds involved A major example of this hazard was demonstrated in the 2000 Baia Mare cyanide spill, when a breakGold mining Wikipedia
