There are alternative lowercarbon routes to steel production. The main one is DRI+EAF, outlined below.. Steel production, stage by stage: 1. Mining. Extracting iron ore is relatively carbon efficient ( tCO 2 e / t) compared to other phases of steel production and other mineral extraction.. However, the quality of iron ore deposits in different geologies radically varies.

Reserves data are collected from Indian Minerals Yearbook and EPWRF website. Reserves of all the minerals have declined from 1995 to 2015. The rate of decline in bauxite is higher than manganese ore and iron ore. Though there was an increase in iron ore reserve from 2000 to 2010, it started falling sharply from 2010.
