The Monaca Electrothermic Smelter - The Old Becomes The New

The Zinc Corporation of America Monaca smelter continues to use the St. Joe-developed electrothermic process for producing zinc metal and zinc oxide. As we enter the 1990s, the electrothermic process flexibility permits treatment of larger quantities? and lower-grade zinc-bearing recycle materials. A new sinter plant having one large sinter machine will increase sinter feed production required to meet our capacity target of 150,000 tons per year.
