Ion exchange resin has been used to recover value metal in the uranium and gold industry through resin in pulp/leach and similar carbon in pulp/leach processes but thus far it has not been
Furthermore resin bead size and mechanical durability improvements have led to the fact that Resin in Pulp RIP technology can be considered as a technical and viable process option for the recovery of metal from pulp streams Evaluations into using Pumpcell and RIP technology for the recovery of gold base metals and uranium have been
The potential for resin in pulp RIP to replace CIP/CIL is discussed The use of cyanide has generated environmental concerns because of its toxicity and therefore research on alternative gold recovery processes using non toxic reagents is considered The key candidates are ammoniacal thiosulphate thiourea and halide solutions
In this paper one strong acidic one strong basic and one weak basic ion exchange resins considered as exhausted in an industrial demineralizing plant are screened for gold recovery from cyanide on the observed ability for the recovery and on the ease of regeneration the weak base anion exchanger Purolite A 100 is selected This spent
gold cyanide and the ability to enhance the extraction of gold from refractory and pregrobbing ores is sought The world s first commercial application of the resin in pulp RIP process for precious metal recovery occurred in the Soviet Union Fieming 1982 Resins are more vcrsatile suhstratcs than activated carbon becausc
Additionally a strong durable resin is required especially when contacted directly with pulps At the same time resin in pulp applications desire a large resin bead for ease of separation of the loaded resin from pulp These are a few of the items on the wish list of the metallurgist As often happens the optimum characteristics of an ion
This review is devoted to an integrated evaluation of the current use and future development of the resin adsorption technique in gold recovery from pregnant thiosulfate solutions Comparisons are firstly made with other recovery techniques including precipitation activated carbon adsorption solvent extraction electrowinning and mesoporous silica adsorption A detailed
Direct cyanidation of the carbonaceous gold ore used in this study resulted in less than 2% gold extraction in 24 hr RIL cyanidation resulted in about 70% gold recovery onto the resin Kinetic experiments indicated that 50% of the gold is extracted after 1 hr of leaching Resin breakage was investigated for as received and preattrited resins

TABLE VI SOLUTION RESIN AND CARBON PROFILES IN THE RIP PILOT PLANT AND IN THE FULL SCALE CIP PLANT TREATING CYANIDED CALCINE AT PRESIDENT BRAND GOLD MINE "Small scale pilot plant tests on the resin in
291 Ion Exchange Resins for Gold Cyanide Extraction Containing a Piperazine Functionality 2 Gold Cyanide Adsorption Mechanism on PS PIP Resins Taking into account the apparent acidity constant of the piperazine group pKH a = l and the IR and XPS results the following reaction describes the gold cyanide adsorption process P1NR2H X
Ⅲ Resin pulp gold extraction process It means that by ion exchange resin gold also can be extracted from ore pulp Like carbon the process makes gold absorbed onto solid spherical polystyrene resin beads instead of activated carbon grains Application Raw ore and concentrates Benefits Large adsorption capacity;
In this study Resin in Pulp RIP technology is used to separate Pb from a chalcopyrite slurry Solvent impregnated resin Lewatit® VP OC 1026 which contains di 2 ethylhexyl phosphoric acid D 2 EHPA in a macroporous polystyrene matrix was used as the functional group exhibits selectivity for Pb over Cu Adsorption pH kinetics as well as resin
With the Western Areas pulp the reverse was true because of the high concentrations of copper and nickel in solution Finally with the President Brand pulp resin inpulp was significantly superior to carbon in pulp owing mainly to the inherently slow rate of gold extraction from calcine by activated carbon
This comprehensive article provides an in depth look at the gold extraction process and its implications for the minin Explore the rich history of gold mining and processing delve into various extraction methods and discover the machinery used in gold extraction plants Resin in Pulp RIP and Carbon in Pulp CIP These are modern
Hailan produces HAL LAN D301G Gold extraction resin Macroporous Anion resin is a gold selective resin specifically designed for use in resin in pulp and pump cell processing Gold has been valued for its beauty malleability and non corrosive properties for millennia
A systematic review of gold extraction Fundamentals advancements and challenges toward alternative lixiviants August 2022 Journal of Hazardous Materials 440 6 129778
Application of ion exchange resins to the recovery of gold is described Significant developments around gold selective anion exchange resins and the commercialization of at least two of these products have made resin in pulp RIP available as an alternative to CIP for the upgrading of gold from cyanided pulps
Significant developments around gold selective anion exchange resins and the commercialization of at least two of these products have made resin in pulp RIP available as an alternative to CIP
Resin in pulp as an Alternative to Carbon in pulp Much attention has been focused at the Council for Mineral Technology Mintek on the carbon in pulp CIP process for the extraction of gold from cyanide media The successful development of this process led to a decision that the resin in pulp RIP process should be
The current approach in the gold extraction industry is to develop highly selective resins 3 for the uptake of the Au CN 2 − species Selective resins are normally characterized by a slow rate
05 Resin gold extraction technology For the treatment of ore pulp containing organic matter mud carbon and arsenic minerals the resin ore pulp method is better than the carbon method and the production cost is lower The ion exchange method is more effective for ores containing substances that adsorb gold such as clay ore containing
