2005-1-1  Publisher Summary. 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 ...

APPLICATION OF RESIN IN PULP TECHNIQUE FOR ION

2014-6-28  The resurgence of Resin-in-Pulp technology in gold and uranium industry is mainly due to two advancements – (i). Development of mechanically resilient polymer beads and (ii) Resin transfer pumps. Already many upcoming uranium ore processing plants in Canada, Australia and South Africa are adopting the “RIP” process.

Review of gold extraction from ores - ScienceDirect

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.

2003-2-1  A process based on thiosulfate leaching followed by resin-in-pulp gold extraction was developed to treat the carbonaceous, preg-robbing ores of Barrick’s Goldstrike orebody in the Carlin Trend of Nevada. These ores have proven to be amenable to thiosulfate leaching under mild conditions. Gold leaches rapidly as the gold thiosulfate complex, which, because of its low affinity for graphitic ...
