The gold-cyanide complex solution is passed through a bed of activated carbon, which adsorbs the gold complex onto its surface. Step 4: Desorption and Recovery. The loaded carbon is treated with a strong solution of hot caustic and cyanide, which breaks down the gold-cyanide complexes, freeing the gold ions. Balanced Equation:
The Earth's crust contains metals and metal compounds such as gold, copper, iron oxide and aluminium oxide. Useful metals are often chemically combined with other substances forming ores: A metal ore is a rock that contains enough of the metal to make it worthwhile extracting

The gold(I) and gold(III) compounds that are of the greatest importance to the extractive metallurgist are listed in Table 15.1, which also provides information on the co-ordination numbers and stabilities of these complexes.
In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press. …

Elsner's equation is generally accepted as expressing the action of gold in dilute cyanide solutions; 4 Au + 8 KCN + O2 + 2 H2O = 4 KAu (CN)2+ 4 KOH. Thus, when fresh surfaces of gold are exposed to the action of cyanide …
In the metallurgical extraction of silver and gold, an alloy of the two metals is often obtained. The alloy can be separated into Ag and Au either with concentrated $mat{HNO}_{3}$ or boiling concentrated $mat{H}_{2} mat{SO}_{4},$ in a process called parting. Write chemical equations to show how these separations work.

The Chemistry of Gold Extraction is an extensively revised and comprehensively updated edition of the well-known reference first published in 1992. It provides the broad base of knowledge that is now required by all those working in the gold extraction and gold processing industries. The book bridges the gap between research and industry by emphasizing the …
It has been traditionally accepted that gold complexes in aqueous solution can exist in one of two oxidation states, the aurous ( + 1) or the auric ( + 3), and that all the gold complexes of hydrometallurgical interest fall into these two groups.
Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening.
For example, the below equation can be written in 2 different ways: Bad: IF(Pump_ON == True, Outflow, 0.0 l/s) Good: IF(Pump_ON, Outflow, 0.0 l/s) Because the first method is redundant, it is better to write it with only the conditional output. Decimal Numbers.
