Book excerpt: The resin-in-pulp (RIP) process was developed primarily for the recovery of metals from high volumes of low-grade pulps, as is the case in the gold processing industry. However, this technology can also be applied to the recovery of soluble metals from solid residues on base metal plants. Applications for the RIP process include the scavenging of valuable metals from leach and precipitation residues, especially where the solids have poor filterability of settling characteristics. The RIP process will improve overall plant recoveries, and it may be possible to decrease the filter duties of the degree of washing on the filters. In addition, the barren stream from the RIP operation may reduce any environmental impact significantly.^L^LBilliton Process Research (BPR) commissioned Mintek to investigate the metallurgical and economic feasibility of a resin-in-pulp process for the recovery of copper from bioleach counter-current decantation (CCD) underflows. Batch laboratory testwork and a continuous mini-plant campaign was conducted in order to optimise the process parameters. The results were used to conduct a preliminary sizing and costing study, in order to evaluate the economic viability of the RIP technology for this application.
