Strong base gold selective (Minix/ Dow XZ 91419) resin is used at Penjom in Malaysia and Gedabek, Azerbaijan. Gold selective medium/strong base guanidine based AuRIX 100 resin is used to treat high grade solutions in Gekko intensive leach systems, while .
Review of gold extraction from ores. ... 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 ...
During this process, the cyanide leaching solution passes through columns filled with ore. The process is highly effective for removing gold from low grade ore. Resin Recovery Technologies Resin RIL (Resin-in-leach)/RIP (Resin-in pulp) In recent years, resin is replacing carbon as the gold .
These include Avocet Mining's Penjom Gold Mine in Malaysia and Anglo Asia's Gedabek mine in Azerbaijan. In most cases, the choice of adsorbent was forced by the complex nature of the ore which made the use of activated carbon uneconomical. The main advantages of using resin over carbon are: • Improved gold recoveries from preg-robbing ores;

This chapter gives an overview of the development of anion-exchange resins for the recovery of gold cyanide from cyanide leach liquors in resin-in-pulp (RIP), resin-in-leach (RIL) and resin-in-solution (RIS) circuits. Three gold-selective anion-exchange resins are currently available commercially— namely, Minix, AuRIX, and AM2B.

DL301 is a macroporous-type strong base anion exchange resin efficient for extraction of uranium complexes in in-situ (ISL), batch or heap leaching and Resin-in-Pulp (RIP) processes. Thanks to its specially graded particle size this resin is particularly suitable for use in RIP processes. The macroporous structure of the resin ensures regeneration efficiency and lower volume of desorbates ...
Aug 24, 2014· Modern technology has improved the process of using chlorine as a method to dissolve gold. Resin technologies have virtually eliminated the early problems associated with using chlorine and the ...
DuPont produces AmberSep™ 91419 Developmental Anion Resin, a gold-selective resin specifically designed for use in resin-in-pulp and pump-cell processing. For information on how to use AmberSep™ 91419 in gold mining applications, contact us.
The ultra-fine-grinding and resin-in-pulp with pH value of 10 are used to extract gold from pyrite roster cinder. During leaching process, aluminium oxide ball is used as stirring medium, hydrogen peroxide as leaching agent and sodium hexametaphosphate as grinding agent.

resin-in-solution (RIS) has become an alternative for the upgrading of gold from clarified solutions. Mintek developed a gold-selective resin, Dowex-Minix, which is being manufactured and made commercially available by the Dow Chemical Company. Although Mintek has been promoting resin-in-pulp (RIP) over the past
Feb 26, 2002· Resin-in-pulp method for recovery of nickel and cobalt ... The first commercial resin-in-pulp gold extraction plant was the Golden Jubilee Mine in South Africa (see C. A. Fleming, "Recovery of gold by Resin-in-pulp at the Golden Jubilee mine", Precious Metals '89, Edited by M. C. Jha and S. D. Hill, TMS, Warrendale, Pa., 1988, pp. 105-119 ...
The first facility to use resin-in-pulp (RIP) ion-exchange technology commercially to recover gold from cyanide pulp was at the world's largest gold mine, in Muruntau, U.S.S.R. Resin-in-pulp is now used widely for gold extraction in the U.S.S.R., and RIP processes offer definite economic advantages over carbon-in-pulp processes.
Resin-in-Pulp and Resin-in-Solution. ... The synthesis of a new macroporous anion exchange resin with two of weak-base functional groups for extracting gold from cyaniding pulp was presented.
Ion Exchange Resin Recovery. In recent years, resin has begun to replace carbon as the gold recovery substrate of choice, for both resin-in-leach and resin-in-Pulp. The process used in resin recovery is similar to that of carbon, but the gold is adsorbed onto solid spherical polystyrene resin beads rather than activated carbon grains.
separate resin and pulp are 500-600 µm. The resin particles are thus roughly 800 µm larger than the gold particles, and 270 µm larger than the screen apertures, allowing easy separation via screens. The mechanical strength of an adsorbent can be determined via a number of different laboratory-scale tests.
Typical process of extracting gold from resin in pulp . The resin in pulp process is similar to the carbon in pulp process for the extraction of gold without filtration. At present, it is mainly used in the traditional cyanidation process containing clay, graphite, asphalt shale, iron oxide and other natural a. .
A process is provided for the direct recovery of nickel and cobalt from a nickeliferous oxide ore leach slurry by ion exchange. A nickeliferous ore is leached with mineral acid to solubilize the metals. The resulting leach slurry is contacted with ion exchange resin, which selectively loads the nickel and cobalt from the pulp. The resin is separated from the leach slurry by screening and then ...
Resin in pulp (RIP) technology . Originally the proposed RIP/ IX technology was developed in 1950s for the uranium industry. It became the first really continuous extraction process. Nowadays, the technology is utilised in uranium and gold industries and in the recovery of their by-products. The RIP/ IX plants process millions tons of minerals ...
