Note that using these reconciled results the gold recovery through the plant is lower than the one obtained during the preliminary sampling camping, because in the latter the plant was not at a strict steady state condition
GOLD RECOVERY TECHNIQUES We provide complete training, guidance and consultancy for the recovery of precious metals i.e. gold, silver, platinum and palladium from all kinds of electronic scrap (like computer mother boards, different kinds of processors, RAMs, hard drives, cellphones,and all other devices in which these precious metals are used).
Fill hydrogen peroxide H 2 O 2 40ml per 2000 ml melted gold chemical water. stir it together and wait for 5 minutes. You have to fill hydrogen peroxide H 2 O 2 in melted gold chemical water to destroy cyanide chemical structure. So, it is not fully element. It cannot melt gold. If we do not fill hydrogen peroxide H 2 O 2 That makes the next step gold piece melted and change into solution.

(cyanide leaching or cyanidation) by McArthur and Forrester in 1887 [2]. A basic flowchart for the recovery of gold from its ore is provided in Figure 1. Figure 1 Basic flowchart for gold recovery. The major categories of commercially viable recovery processes include the following [ 4, 5]: 1. Amalgamation (with mercury) 2.
Cyanide use in mining Gold typically occurs at very low concentrations in ores – less than 10 g/ton. The most used process for gold extraction is hydrometallurgical recovery (gold cyanidation), which involves a "leaching" step during which the gold is dissolved in an aqueous medium, followed by the
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.

and 2 wt% sodium hydroxide. Sodium cyanide is sometimes added to the solution but it is frequently unnecessary. The solution is heated to about 190 deg-F and pumped through the carbon stripping vessel at a flow rate of about 2 Bed Volumes per hour. Gold and silver values are recovered from the pregnant solution by electrowinning and the barren ...
Carbonaceous gold ores can have the carbon adsorb the gold onto its surface, and as a result will not be recovered from the pregnant solution. Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30%, which is not a worthwhile venture.
