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.
