In gold cyanide extraction, a large amount of cyanide tailings produced. The annual discharge of cyanide tailings by Chinas gold industry exceeds 24.5 million tons. Cyanide tailings contain a high amount of undissolved cyanide and valuable metals, performing storage or landfill treatment alone not only causes damage to the environment but also leads to a great waste of resources [12] , [7] .

how do i extract gold from tailings via AR bath - Gold ...
Jul 27, 2014 · Too many of the constituents of ores react with acid, so it is consumed without doing the desired work. You can end up with hundreds of gallons of waste material to deal with, all the while recovering only traces of gold. Electrolysis (electrowinning) has been used with success, as has activated carbon, but both with cyanide, not acid.
Processing, smelting and refining gold | World Gold Council
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 Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
Gold cyanidation - Wikipedia
The stone reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au (s) + 8 NaCN (aq) + O 2 (g) + 2H 2 O (l)→ 4 Na [Au (CN) 2 ] (aq) + 4 NaOH (aq) In this redox process, oxygen removes, via a two-step reaction, one electron from each gold atom to form the complex Au (CN)−. 2 ion.

In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au（CN）2ˉ is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.
