|A dynamic simulator for CIP / CIL gold recovery plants has been developed at the Julius Kruttschnitt Mineral Research Centre within a collaborative, industrially - funded AMIRA project and with the participation of the Western Australian School of Mines. The simulator incorporates kinetic models for the leaching of gold from ore and its adsorption onto activated carbon, and the residence time distributions of the leach liquor, pulp solids and carbon in the circuit. Features of the simulator include the effects of gold loading distributions on both the ore and carbon on reaction rates, and the difference in residence time distribution between the leach liquor and pulp solids. The simulator allows for the estimation of kinetic model parameters from full scale applications, as well as some scale - up of parameters from laboratory batch tests. The laboratory tests were conducted at the WASM as part of the collaborative research project. The simulator can operate in both steady - state and dynamic modes, and has potential applications in design, optimisation and control of CIP / CIL plants.|
