Program Purpose:

Canada produces 6% of the world's supply of refined zinc while CEZinc alone produces 265 000 tons at itsx000D
Valleyfield plant. This process is energy intensive and its need for electricity hits 45 M$ per year. Increasingx000D
the energy efficiency is the key factor to make the company more profitable and competitive. A promising wayx000D
to reduce power consumption at CEZinc is to perform a substantial technology change by replacing Pb-Agx000D
anodes with coated Ti anodes. Although such a technology change represents a considerable energy saving, itsx000D
implementation is not trivial and a number of issues must be addressed before. This exploratory project aims atx000D
identifying and validating these issues. More specifically, the focus will be made on the effect of newx000D
technology on the operation conditions of the zinc electrolysis cells, allowing better control of Mn in thex000D
electrolyte since the Mn buildup in the electrolyte is the negative consequence of using Ti anodes.
