The MACH and preg - Know More

04-08-2021 0183 32 The concern is that the high level of aggression within the MACH may break down graphitic preg-robbers, so increasing their surface area and potentially also their preg-robbing activity The counter-theory to the above is that the MACH could 1 Potentially oxidise adsorption sites on the preg-robber and so reduce preg-robbing activity 2...

The Role of Chlorine in the Passivation of Preg Robbing , - Know More

Chlorination of organic matter by direct injection of chlorine gas or hypochlorite has been investigated metallurgically worldwide with little understanding of the basic chemistry of the passivation mechanisms in- volved In this paper, chlorination of carbon is attributed to oxidation-reduc- tions, resulting in surface halogenation of graphitic or amorphous carbon...

PROCEDURE FOR CHARACTERIZATION OF CARBONACEOUS , - Know More

Normalized preg-robbing indices are introduced which more accurately describe the preg-robbing capacity of carbonaceous matter across a set of samples and allow for comparative analysis between different ores or between composite samples within the same ore body...

The preg-robbing phenomenon, ie, gold precipitation back onto the gold ore or concentrate during gold leaching, in chloride as well as in cyanide media, has been known for decades Aylmore, 2005 Almost all gold lixiviants are known to suffer from preg-robbing However, the nature and the extent of preg-robbing and gold complex stability vary...

Experiments for the composite sample of preg-robbing carbonaceous gold ore 3511 Micro flotation Given the carbon content of the sample was on the order of 35 it was decided that the carbon content be upgraded to in order to provide a better opportunity to monitor changes to the preg-robbing capacity of the CM in the ore...

Assessment of Options for Economic Processing of Preg , - Know More

Using these relatively simple plant modifications potentially allows a plant to treat ores with preg-robbing index PRI values up to one When PRI values rise to 13 - 16, leach recoveries can drop from gt 85 per cent to...

Characterization and blinding of carbonaceous preg - Know More

Abstract Preg-robbing amorphous carbon and graphite were identified in two ore samples using optical microscopy to identify the mineral phases, followed by the direct analysis of gold on these phases using electron microprobe analysis Pyrite showed a slight preg-robbing effect The samples were also mineralogically quantified, and the mica and chlorite that was present was ,...

PDF Evaluation of preg - Know More

Preg-robbing Index Tests The industry standard approach for detection and quantification of preg-robbing is to run in parallel a cyanide leach test with a gold spiked cyanide leach The cyanide leach effectively determines the amount of cyanide soluble gold in the ore, while the gold spiked leach indicates the capacity of an ore to adsorb gold I cyanide from solution...
