Abstract

Up to 10% of the soluble nickel and cobalt can report to the tailings of a pressure acid leach (PAL) process for the recovery of nickel from lateritic ores as a result of the difficulties associated with the poor settling characteristics of the autoclave discharge. This paper describes the results of laboratory and pilot-plant investigations aimed at establishing the potential for the application of a resin-in-pulp (RIP) process to improve the overall nickel and cobalt recoveries from such tailings. Small-scale batch tests in the laboratory established the technical feasibility and this was followed by several campaigns using a continuous six-stage miniplant which demonstrated that the process could achieve the desired results and which enabled a pilot plant to be designed. The integrated pilot plant operated on site at a local plant over a period of several months. The paper will discuss the results from this testwork, which has culminated in a preliminary process design for a full-scale plant. In addition, the more fundamental aspects associated with the adsorption and elution processes have been investigated and process models developed for these operations.
