Aug 18, &#; The final step in production is smelting This process involves melting the concentrate in a furnance to extract the metal from its ore The ore is then poured into moulds, producing bars of bullion, which are then ready for sale Closure and reclamationSmelting maximizes the separation of ore from gangue minerals The concentrates undergo smelting and converting in a furnace at a high temperature to produce a silicate melt (slag) and an immiscible melt (matte) due to density differenc The flux (limestone) is added to the furnace to reduce the melting temperature in the matte.

Smelting and Refining Operations Adapted from the 3rd edition, Encyclopaedia of Occupational Health and Safety In the production and refining of metals, valuable components are separated from worthless material in a series of different physical and chemical reactionshave to be processed further for gold recovery By smelting the concentrates directly, a process could be developed that generates a final product in one step Smelting is a technique that is already known to the miners, as they smelt sponge gold after amalgamation and retorting/heating The one-step smelting technique was tested.

Gold Smelting Process - SciencingCopper extraction - Wikipedia

Apr 24, &#; The first step in the gold smelting process occurs when ore containing gold is mined from the earth At this point, the crude binding matter and the gold metal need to be separated This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnaceHowever, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first Initial concentration techniques included hand-sorting and gravity concentration.
