4、Desorption and electrowinning : the desorption of activated carbon and electrowinning the liquid gold are completed in a closed system, in a high temperature and high pressure, activated gold carbon after desorption and electrowinning become gold pulp and barren carbon .
In the gold industry, the use of activated carbon to separate gold from cyanide leaching solutions has become an industry standard for efficient gold recovery in Carbon in Leach (CIL), Carbon in Pulp (CIP) and Carbon in Column (CIC) operations. Get Price cyanide gold leaching machine essentialgap
5. Electrowinning. The goldrich solution from the elution process, the electrolyte, is circulated through three parallel electrowinning cells over a period of 16–24 hours. Gold and other metals are precipitated on steel wool cathodes, which are submerged in the circulating electrolyte.

The solution then passes back through the loaded carbon extracting more gold and other metals. This process continues until the carbon has been stripped. The cathodes (wire wool now plated with gold and other metals) are removed and placed in acid. The acid burns off the wire wool and other metals such as copper, and leaves a sediment of gold and solution of acid and dissolved silver. The acid and silver .
The leaching circuit, also referred to as CarboninLeach (CIL), is where cyanide is added to dissolve the gold. In this part of the process the gold is dissolved, though the cyanidation of the milled ore then adsorbed out of the slurry solution and onto carbon molecules.
The operation consists of an openpit mine and heapleach facility, with gold recovery by resininsolution and electrowinning. The mine is expected to produce more than 300,000 oz of gold during its initial sixyear mine life. At Gedabek, ore is crushed, screened and agglomerated before stacking in conventional heaps.
Intensive leaching in an inline leach reactor is essential to recover the gold from the gravity concentrates. Tabling is not a preferred option since recovery is lower than intensive cyanidation and any gold losses to table tails will report to CIL where recovery is reduced by .

the solution, which rapidly displaces the gold in the Au(CN) 2. Once the solution has been depleted of the gold cyanide, it is called barren solution and is returned to the heap to continue the leaching process. Long term use of the solution will cause the pH of the solution to change, so makeup caustic and / or lime may be added
In the case of the higher energy consumer, the pregnant liquor is pumped five miles from the leach site to the SX/EW plant. The electrowinning of copper requires considerably more electrical energy than does the electrorefining process an average of about 8 MJ/kg for .
A process and system for recovery of gold from an ore having the steps of i) providing the ore containing the gold to be recovered, ii) leaching the ore in an oxidative chloride medium, including a nitrogen species to produce a solution comprising gold; and iii) recovering the gold from the solution. The gold in a preferred embodiment is recovered from refractory and carbonaceous ores.
However, gold dealers usually do not pay the current, while the smaller, lighter. Fig. Hand fed sluice in South Africa For the electrowinning process, the gold solution is added to a cell using a current of 12 Volts and 60 amps causing . heap leach 911 Metallurgist. columns or alternatively staged heap leaching and direct electrowinning.
