This method of gold smelting uses a flux, a substance made of borax and sodium carbonate that removes impurities from gold. The first step is to buy a crucible container, used for holding the gold as it melts. This is a …
Thanks for reply. Yes floatation is a knonwn banificialer process, have floatation cell working. Somehow 1600c is really an expensive idea, ore is worth to process. consider the mathod described by "rusti2" . Smelting with iron and remove slag and adding new material till iron is concentrated with values.
