3.1.1 Group 1 – mining and beneficiation as a single stage. Most of the studies considered beneficiation altogether with the mining operation. For example, Awuah-Offei and Adekpedjou carried out a review scrutinising the very first LCAs applied to the mining sector.This work is focused on the extraction stage, and it mentions the …

The mining sector accounts for a quarter of all economic activity in the province and is also the largest single sector, providing employment to 5.2% of the province's workforce. Second largest mining industry of the 9 provinces. The major mining activity in the province is centred on the coal and lignite industry.

This is mainly due to the reason that most hematite iron ores of India are very soft, generating around 35–40% of fines and slime during the process of mining, beneficiation and preparation of sized ore. The tailings and slimes generated from the hematite ores are 10–30% of the run of the mines and are discarded as waste . The …
