Munix provides simulation-modelling software, where the gold adsorption circuit of brown-fields or green-fields RIL/CIL or RIP/CIP and elution/desorption circuits are accurately modelled. The modelling, which simulates the processing circuits using metallurgical data to select the optimal processing conditions and recovery plant configuration, provides a clear picture for the client in order to maximize gold recovery and eliminate unnecessary costly trialling and guess-work.
