preg robbing Explanation: Je ne suis pas spécialiste, mais j'ai trouvé plusieurs sources gardant ce terme en anglais, par ex. : Preg-robbing Ores Minerais contenant une matière carbonée, qui absorbe (vole) de préférence de l'or dans des jus forts de cyanure, ce qui empêche la récupération d'anciennes matières. http://www.ressourcescampbell.com/fr/glossary.php Les minerais de transition présentent un effet de preg-robbing important (à cause de la présence de graphite dans le minerai) http://www.49west.com/Semafo Samira 43-101 Dec 06.pdf Definition: Preg-robbing is the term used to describe the loss of gold by the re-adsorption of dissolved gold cyanide onto carbonaceous ore components. This robbing of gold from the pregnant liquor (ie the gold cyanide solution) can be a significant cause of low gold recovery in conventional carbon-in-pulp processes. |

capture Explanation: The preg-robbing capacity of the native carbonaceous component of the ore can be augmented by adding recycled carbonaceous matter or finely ground carbon to the ore-lixiviant mixture. La capacité de capture de solution de lixiviation du constituant charbonneux naturel peut être augmentée par addition de substance charbonneuse recyclée ou de carbone finement broyé au mélange minerai-solution de lixiviation. http://www.wipo.int/pctdb/en/wo.jsp?wo=1994006944 |
