Orogenic gold ore is a type of gold ore that is formed by the deformation and metamorphism of pre-existing rocks, such as sedimentary rocks or volcanic rocks. It is often associated with quartz veins or shear zones. The processing of orogenic gold ore involves crushing the ore to a fine powder, which is then mixed with water to form a slurry.

There is no method for separating gold from silver, or other precious metals, when smelting. The ore containing the metal when melted will form an amalgam – an alloy of gold and silver, or whatever precious metals are in your concentrates. Let the refinery separate precious metals – it9s really the easiest and cheapest in the long run.
