Recovery of the gold as amalgam minimizes problems encountered in assaying mill products containing erratic free gold values and increases the over-all gold recovery.

The gold concentration on the feed leach liquor ranged from 0.428 to 0.054 oz of gold per ton (14.6 to 1.8 g/mt) of solution. Capital costs at the front end of a CIP plant are based on incoming flow rate, and are not a function of the gold grade.
Colt Resources has already invested €60 million in its plan to begin gold and tungsten mining at two sites in Portugal which once under construction will deliver hundreds of jobs for local people, thus helping to …
With ores containing up to 0.8 per cent organic carbon and 1.5 per cent pyrite, the method worked quite well giving 83.0 per cent extraction of gold and a carbon loading of 1000 grams of gold per tonne in locked batch tests from an ore containing ten grams of gold per tonne.
The batch time recovery data of Figures 1 and 2 has been curve fitted to a modified first order rate model frequently used by this author and others in kinetic studies, Klimpel (1980, 1989, 1995) and Dowling et. al. (1986).
What is cyanide and why do we need cyanide-free gold leaching process? Cyanide (CN –) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H 2 O) to form a gold cyanide complex (Na [Au(CN) 2] ) and sodium hydroxide (NaOH). The chemical reaction dubbed the "Elsner Equation", named …

A recovery time curve which exhibits a step change increase in recovery after a time consists of two separate components. This can be caused by stage addition of reagents mid-way which reactivates mineral or by the presence of a second component that is free to float after the first component has been recovered.
Gold recovery was about 41 to 47 percent from the feed to the pan concentrate. Rougher flotation recovered between 50 and 54 percent of the feed gold to the rougher concentrates. Gold rougher recovery is shown as recovery from the rougher circuit feed
