Zinc ash is a raw material that is used by many different chemical industries for the preparation of nutrients for the soil. Several major chemical industries and zinc ash importers produce zinc ash to be blended with agricultural grade zinc oxide. Other than that, the metallic form of zinc ash is used for galvanization and other processes. Some industries smelt both processed ash and unprocessed ash to recover zinc in the metallic form. It is hazardous for humans, animals and plant alike because it contains lead at concentration.
