Secondary Zinc Production

Zinc for crop production | UMN Extension

Zinc (Zn) is an essential micronutrient for plant life. In Minnesota, while some soils are capable of supplying adequate amounts for crop production, addition of zinc fertilizers is needed for others. Zinc is a recommended micronutrient in fertilizer programs for production of corn, sweet corn, and edible beans.

Secondary production. Over 35% of the zinc used annually is from recycled metal. Much of this comes from zinc-coated steel which, for example, has been used for rooing. This is placed in the Electric Arc Furnace being used to recycle the steel. Zinc is relatively volatile and leaves the furnace with other gases. It is collected on cooling as zinc dust.
