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.
Over time, gold and silver prices tend to move in concert, mostly in opposition of depreciating fiat currencies. Recently, the price of gold has been about 60 times the price of silver, while historically it was closer to 20 times. Silver prices tend to be more volatile than gold…

Start by reducing the size of gold to smaller. Melt gold, pour gold while melting through a 2 mm sieve into the water. Reducing the size of gold to smaller Will help in the process of aqua regia to make gold into the solution more quickly. aqua regia is composed of 2 chemical substances, 1 nitric acid, 3 hydrochloric acid mixed together.
Silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration,
Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching.
Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.
Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.

With the rising price of gold and the limited amount of mineable land, people are now focusing on the recovery of fine gold. Some rivers of the world have been sluiced as many as 6 times, yielding profitable gold each time – and demonstrating that traditional sluices can have very poor recovery. Gold Processing Equipment like the IGR500 focuses on the recovery of the Fine Gold.
