Abstract
Mass and energy balance simulations form an integral part of metallurgical process design, from concept level studies through to detailed design. To build an efficient process plant, that maximises production with least capital and operating costs, an accurate model of the flows and the chemistry involved in the process is indispensable for all but the simplest of processes. For existing operations, a mass and energy balance is essential for optimisation of the existing process. Also, the consequences of proposed modifications to the process can be assessed quickly, before purchasing any new equipment. In an engineering study, a mass and energy balance is usually created at the concept level, with limited detail, and expanded in the later study phases to contain more detail of both the chemistry and the minor process flows. The selection of tank and pond volumes, pipe diameters, materials of construction, power requirement for motors, and most other design parameters rely on accurate predictions of the conditions that the plant will encounter through the life of the resource.
