Smelting Shaker Table Concentrates - Gold Refining Forum.com

Depending on the acid strength and temperature leaching time can vary from one to sixty days. If your smelting has poor results after the acid leach then either you have a problem with the rock particles present in the smelt or your flux is wrongly composed. Generally if the base metals have been properly removed then the flux can be just borax.
