The development of models of INCO's Copper Cliff operations using a computer spreadsheet program is discussed. Empirically developed metallurgical relationships were utilised. The paper concentrates on models of the pyrometallurgical processes but discusses applications such as optimisation of operating parameters, evaluation of feed changes and custom or recycle materials processing. The models were initially developed using a spreadsheet program on a personal computer. The requirements of plant engineers and process operators for significant increases in operating speed led to the transformation of some of the modules. The paper is presented in two parts: 1. The development of the modules using a spreadsheet. 2. The transformation of a module into a high speed tool for process control. The application of the technique to other pyrometallurgical processes is discussed.
