Chlorine is bubbled through molten dore, converting the metals into chlorides.
Two common methods are the Wohlwill process and the Miller process.
The Wohlwill process uses direct and alternating currents to electrolyze dore gold in a chloride solution. Gold on the dore anode dissolves and accrues to the cathode

The cost to refine gold dust can vary depending on the amount of gold dust you have, the purity of the gold, and the refining method used. Generally, refining can cost anywhere from a few dollars to several hundred dollars per ounce. It is recommended to contact a reputable refiner for an accurate quote based on your specific situation.

When gold is refining, it is called smelting. Smelting involves heating the gold to a high temperature to separate it from impurities and other metals. The purified gold is then typically cast into bars or ingots for further processing.
You can find more information about the process of refining gold online at the Precious Metal Refining Info website. You can also watch a video about the process at the YouTube video streaming website.
The most effective methods for extracting and refining a pool of gold include mining, crushing, and processing the ore to extract the gold. This is typically done through techniques such as cyanidation, smelting, and refining processes like electrolysis or chemical leaching.
Do you mean pure gold, or the process of refining gold? no to the first yes to the second
Gold is typically extracted from gold ore using a combination of chemical processes. The most common method involves cyanidation, where cyanide solution is used to dissolve the gold from the ore. The dissolved gold is then extracted from the solution through adsorption onto activated carbon, followed by refining to obtain pure gold.
The Balbach-Thum process is a method used in metal refining to extract gold and silver from ore. It involves melting the ore with lead to form a lead-silver-gold alloy, which is then treated to separate the precious metals. The process is known for its efficiency in recovering gold and silver.
