Abstract

The Minamata convention addresses the issue related to mercury poisoning and aim to reduce mercury pollution, as mercury is one of the major concerns for human health. Globally Steel industry is an important source of anthropogenic mercury release. India being one of the largest steel producing country need to look after into details of mercury emission from steel industry. The raw materials like iron ore, coal contains small amount of mercury, which released during steel production. In this study, field studies have been conducted for estimation of mercury input and release from an integrated steel plant in India. Various raw materials, products and wastes are collected for mercury analysis. Mercury mass balances for individual processes were estimated and sinter, coke production processes are found to be significant contributor. Overall mercury mass balance of the plant shows 31.9% of mercury is released through flue gas in various process along with that coke oven gas and Blast furnace gas are also significant contributor. The mercury emission factor for the studied plant found to be 0.057 g Hg/tonne of hot metal production.
