Reuse of iron ore mineral wastes in civil engineering

Approximately 18,000 ha of land is currently under mining operations in Goa (Kumar, 2000)The present mining rate of 16–21 million ton of ore, with high oreover burden ratio of around 1:3, means that there is a need of removal and disposal of 40–50 million m 3 of waste per year Having exhausted the available area for waste dumps within leasehold area, the mining companies had to procure
