Recovery of Zinc and Iron from Zinc Ash

Zinc ash contains high percentage of zinc and iron which can be recovered and converted into valuable products. This project aimed to produce crystalline zinc sulfate and ferrous sulfate from recovered metals from zinc ash. Bangladesh is an agriculture based country and zinc sulfate is used as one of the necessary fertilizers. Samples of zinc ash were collected from local galvanizing industries in Dhaka, Bangladesh. The major metal components in the sample were zinc, iron and aluminium.
