The proposal includes an open cut iron ore mine, ore processing areas, waste dumps, waste fines storage facility a railway corridor and an infrastructure corridor. The proposal will have an operational mine life of than 30 years and will generate up to 70 million tonnes a year of product. The proposal is.Apr 09, 2015 Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth’s crust.
This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Environmental hazards are present during every step of the open-pit mining process.
