The paper discusses how automation is steadily proceeding throughout all areas of the electrolytic zinc industry. Fluid bed roasters with integral sulphuric acid plants are now on -computer control. Highly efficient, continuous leaching and purification stages, with feed-forward predictive and optimisation computer control, precede electrolytic cells with on-stream solution analysers and automatic stripping of deposited zinc. Controlled electric induction furnaces feed continuous casting lines, equipped with automatic stacking and strapping, machines, after computer based metal analysis has confirmed metal purity or alloy composition. The paper also discusses the use of computer models tied to process control systems, and the equipment and solution measurements that could be automated with advantage, using modern micro-based controllers and analysers.
