Gold refining This refers to processes used to processes used to extract and separate the precious metals in mined material, dor, and from recycled products (jewellery and electronics). The main techniques used to remove the final impurities to create high caratage gold are summarised below
Although most gold is produced from alluvial and other surface mining, or from underground reef mining, some gold is produced as a by-product when copper, lead, and uranium ores are refined. An estimated 30 percent of the gold in the U.S. is produced by these means. The exacting process of refining gold.
Two (2) major techniques for refining gold. Generally, gold can be refined using these two-best-known gold-refining procedures Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.
