Estimating process design gold extraction, leach …
ore grading 2.3 g/t, a 1% increase in gold recovery generates incremental revenue of about $1/t-ore at a gold price of $1,300/ oz. For cyanide at a price of $3,600/t delivered to a remote mine site, it takes only 0.28 kg/t-ore consumption to equate to $1/t-ore, or 1% gold recovery. If the ore consumes considerable cyanide to achieve optimal
Effect of Organic Carbon on Gold Leach
Ore sources that are easy to process are limited. Exploration activities involve several increasingly complex ore bodies and require innovative approaches in the extraction process [1,3]. One of the challenges in gold processing is the processing of ores with the Preg-Robbing (PR) effect.

Liquid–Solid Separation in Gold Processing
The flowsheets in Figure 18.1, Figure 18.2, Figure 18.3 illustrate how liquid–solid separation fits into carbon-in-leach (CIL), carbon-in-pulp (CIP), and Merrill–Crowe circuits, respectively. In addition, heap leach, column leach, and gravity circuits also need to have liquids separated from solids, and there are many variations of the flowsheets presented.

Gold Extraction & Recovery Processes
The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation. The leach cycle is normally from 20 to 30 days. When the leaching cycle is complete, a new crushed ore is piled.
