2022 7 15 Preg robbing test. Dried ores were taken through crushing and ball milling to 80% passing 106 pm prior to preg robbing test. Duplicates of each sample weighing 10 g were used to contact 25 ml of 16 pg/mL gold solution and agitated at 200 rpm in an orbital shaker incubator for 24 hours. Each pulp was then filtered and the filtrate analysed for

2021 8 4 Method 1. PRI or preg robbing index involves contacting a 10ppm gold solution with a specified mass of the sample and contacting over a 24hr time period. Gold in solution values are measured and the preg robbing index is then calculated. This is good as it is a relatively simple standard procedure that can be useful for geometallurgical

PREG ROBBING OF GOLD IN CHLORIDE BROMIDE

2015 11 11 preg robbing phenomenon was simulated by carbon addition as finely powdered activated carbon to the gold ore with carbon addition of 0 Test 1, 0.01 Test 2, 0.1 Test 3, 1 Test 4, 5 Test 5, and 10% w/w Test 6 . All the gold chloride bromide leaching experiments were conducted in a 5 dm3 titanium reactor with baffles and a reflux

Preg robbing phenomena in the cyanidation of sulphide

2000 11 1 1. Introduction. Preg robbing is the phenomenon whereby the gold cyanide complex, Au CN 2−, is removed from solution by the constituents of the ore. The preg robbing components may be the carbonaceous matter present in the ore, such as wood chips, organic carbon, or other impurities, such as elemental carbon.

2009 11 20 its capacity to preg rob gold. From this, a simple and robust method has been developed based on the Raman spectra of the sample and carbonaceous material content to predict the preg robbing capacity of an ore. The potential exists to develop a predictive tool using Raman spectroscopy for characterising the preg robbing capacity of an ore.

Preg robbing gold ores

2005 1 1 Preg robbing is an important phenomenon that inhibits gold recovery due to the presence of naturally occurring carbonaceous matter. In case of certain ores, gold recovery by cyanidation is limited by the presence of naturally occurring carbonaceous material that adsorbs gold from alkaline cyanide solution unless steps are taken to prevent this adsorption reaction
