Gold Smelting & Refining Process
The slag contains gold and silver and must be reprocessed in order to minimize the losses of precious metals. A very important element in the smelting process is the flux, which is added to charge in order to remove base metals and other impurities from the Dore bar. ... the material can be sent to the leaching process employed to treat the …
Slag Grinding – ZJH minerals
The hardness of slag is around 6-7 in Moh's scale (harder than cement clinker). For the aim to grind slag (15-20 mm) to a final fineness of 30 microns. After the slag dry, the slag less than 50mm fed into the rolling mill, the slag will be grinded to be powder by squeezing crushing strength by the roller.
