Known technology to reclaim Zinc from Zinc ferrous sulphate Heptahydrate

We are a Hot Dip Galvanizing facility located in Guelph, Ontario, Canada.

We are a closed loop facility and such must deal with all process materials.

A bi-product from our pickling acid regeneration equipment is a Zinc ferrous sulfate ⇦this on eBay or Amazon [affil links] heptahydrate crystal.

My question is can someone tell me if there is technology available out there to reclaim/remove the Zinc from the bi-product (zinc ferrous sulfate ⇦this on eBay or Amazon [affil links] heptahydrate).

I'll check with my Indian operation, reg zinc ferrous sulfate ⇦this on eBay or Amazon [affil links] , and come back to you. In the meanwhile please let know the quantity generated at your plant.

Thanks and best Regards,
