Hindustan Zinc Limited announced that the planned shutdown taken at one of the roasters at Chanderiya Lead Zinc Smelter, has been extended in view of the need to repair and overhaul many major structural components of the roaster to avoid any operational risk in the future. This will result in loss of production of about 25KT of Zinc. The company expects the roaster to come back to operation by mid of October 2021. The company will however ensure balanced approach of supply to all customer in a manner that will have no impact on their operations.
