Gold Smelting Equipment It has been shown that concentrates obtained by gravity devices and cathodes can be smelted directly most the time. Silvergold concentrates can be smelted too. Under this consideration, a concentrate must contain at least 20 oz/t of gold. Obviously, if the higher grades are better and 50 oz/t is a good average value.
For example, If we are assaying a sample of ore for gold we must first divide all the ore as well as possible by grinding it. Usually, 30 grams of this ore is mixed with the flux. The flux is composed of a calculated amount of silica (white sand), lead oxide (red lead or litharge), sodium carbonate (washing soda), and flour, cornmeal, or ...
Gold melting is the process of turning solid gold into liquid, but gold smelting is the process of removing the impurities from the gold by using pressure, heat and chemicals. Historically. The smelting process has been around for thousands of years dating back to ancient civilizations.
You probably can melt gold concentrate if it is reasonably pure. Typically a flux is added to even remelting gold bullion to reduce volatilisation and if it is in a finely divided form the lower melting point flux as a liquid provides better heat transfer to the solids.
