The Gold Quarry deposit is the largest sediment-hosted gold deposit yet discovered on the Carlin trend in northern Nevada. However despite the locales vast reserves the gold is difficult to extract from portions of the deposit. Detailed ongoing mineralogical analyses assure proper treatment of the ore.

Jul 12 2019 8 Methods to Extract Gold The gold beneficiation process of easy to separate gold ore consists of amalgamation gravity separation flotation and cyanide. The choice of the extraction processing method depends on the nature of the ore and the requirements of the product form. The commonly used beneficiation flow as following.
Chemical Leaching. Chemical leaching makes use of the chemical properties of gold to leach it from ore concentrate or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost.
day placer gold production comes from the dredge operating at Hammonton from large placer mines employing the cya-nide process from byproduct recovery in sand and gravel plants from small placer mines and from small dredging op-erations in rivers and streams. With placer mining recovery of the gold from the ore is usually the most expensive phase of the mining operation and
The two gold refining methods most commonly employed to derive pure gold are the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold.

The process works best when the ore is crushed to small pieces before roasting. Additives such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted and the sulfur is driven off the extraction of the gold or silver from the ore is not especially difficult.
Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. The most common method is to roast gold-bearing minerals at temperatures of 450 to 750 C 840 to 1380 F to destroy the interfering sulfides.
