India was the world's second-largest steel producer with production standing at 106.5 MT in 2018. The growth in the Indian steel sector has been driven by domestic availability of raw materials such as iron ore and cost-effective labour. Consequently, the steel sector has been a major contributor

Coal on move, 25 tonnes a minute, is choking Goa, more is

Indeed, it was the ban on mining and the resultant cutoff in export of iron ore — from 43 million tonnes in 2010-2011 to 11 tonnes in 2014 — that cleared the way for coal to come flooding into Mormugao. During the iron-ore export days, the port contributed to 35 per cent of

Environmental impact of mining

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
