Mine closure and reclamation.
The first step related to iron
ore mining that is exploration involves hunting of
iron ore mines.
The rocks and dust from the
location expected to have an iron ore mine is taken
for lab test and analyzed in various ways to
determine the type of iron ore and the feasibility
of obtaining iron from the mine. Based on the
analysis of geological data and feasibility further
actions of mine development are planned.
The second step of mine
development mainly involves building and
accumulation of several facilities, machineries and
amenities required for extraction of iron ore from
the mine. This step includes the necessary
infrastructure development for safe and appropriate
extraction operation. This step also stresses on the
reclamation aspect that would be required after
completing the extraction process.
The extraction operation
includes excavation of iron ore from the mine. This
includes the process of actual digging in the earths
crust for the iron ore. This is a continuous process
that could go on for years depending on the amount
of iron ore deposit in the mine. The extraction
process today involves optimum use of available
latest resources for systematic production of the
iron ore.
The ore beneficiation involves
separation of iron ore from the other rocks. The
beneficial plant needs arrangement for reuse of
water from the mining pit that has exhausted,
treatment of effluents and tailing disposals.
The iron ore mine closure and
reclamation includes waste dump management, dump
stabilization, managing soil erosion, wastewater
management, returning condition of land as prior to
mining so that it is suitable for use. The waste
rock and soil is used for reclamation process. The
soil erosion is avoided by giving proper slopes to
the land. The most important step as far as
environment issues are concerned is the plantation
of trees suitable for the location so as to maintain
the balance in ecosystem.
With latest developments in
technology today various software’s are used to plan
the mining process for extraction of iron ore from
mines. Also satellite data is used to explore iron
ore mines in different location of the world that
makes the process easier than old days.
