Operation of today’s zinc roasting plants is becoming more and more challenging due to declining concentrate qualities. This results in unstable process conditions in the furnace of the roasting plant which can harm product quality.
Operating a zinc roasting furnace in desirable operating conditions is subject to many factors such as feed, air as oxygen flow as well as water addition at different positions. Operating the roaster in a stable and profitable operating window requires careful, regular and anticipatory adjustment of these parameters. To support the operation of such plants, Outotec has developed and commissioned the Pretium Roaster Optimizer, a system that continuously leverages embedded process know-how to operate the roaster in an optimal way for high process efficiency, a consistently high product quality and improved economical KPIs.
This article gives a short review on how Outotec applies modern advanced automation and optimization methods to improve metallurgical process plant operations.
