  A review on adsorption mechanism of gold cyanide complex …

  2022725 · Cyanide is the major leachate for gold production in the mining industry because of its high leaching efficiency, low cost, and high stability [8], [9]. About 90% of the gold ore is produced with cyanidation globally [10], [11]. The gold-bearing ores are mixed with cyanide solution at an alkaline pH and dissolved in the reaction as follows [12]:

  Basics of Gold and Silver Plating

  202419 · Somewhat similar solutions had been prepared using chloroauric acid itself. In practice, the cyanide-containing solution yields finer-grained deposits and is less subject to immersion deposition. Trivalent gold cyanide solutions have also been used in jewelry plating to deposit very bright, adherent layers up to about 5 microns thickness.
