Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, lit. "regal water" or "king's water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange (sometimes red) fuming liquid, so named by alchemists because it can dissolve the noble metals gold and platinum, though not all metals.
The barren slurry, now known as tailings, is pumped to the tailings storage facility (5). In contrast, by the time the carbon reaches the first adsorption tank it has recovered most of the gold and silver from solution. This 'loaded' carbon is then pumped to the elution circuit (6) where the gold and silver is washed off with superheated water.
In the first method, a machine called a "hydraulic giant" uses a high pressure stream of water to knock the gold ore off of banks containing the ore. The gold ore is then washed down into sluices or troughs that have grooves to catch the gold. ... Two other methods of gold refining are amalgamotion and smelting. In amalgamation, the gold ore is ...

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
