25.2 Extracting ores

Surface mining Surface mining is exactly what the word says - digging rocks out from the surface, forming a hole or pit. In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal. Surface mining is also known as open pit or open cast mining. An open pit coal mine.

iron processing

Most iron ores are extracted by surface mining. Some underground mines do exist, but, wherever possible, surface mining is preferred because it is cheaper. Lumps and fines Crushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch).

Mining and Water Quality

Jun 08, 2018The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage. The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water.

mining

A process called in situ mining often accompanies this borehole mining. With in situ mining, a fluid that will dissolve the ore is circulated through the deposit. The fluid, with the mineral in solution, is then pumped to the surface where the minerals are separated from the fluid. The fluid is then reused. Surface mining Inco Limited

Taking the iron mine building as an example it is possible to review how the different production methods differ: Base production method - Determines if miners use only picks and shovels or if they also use some sort of engine-driven pumping mechanism. There are several different pumping technologies which also determine what fuel is used.

Jun 02, 2016ABSTRACT. This study demonstrates substantial removal of iron (Fe) from acid mine drainage (pH ≈3) in a passive vertical flow reactor (VFR) with an equivalent footprint of 154 m 2 per L/s mine water and residence times of 23 h. Average Fe removal rate was 67% with a high of 85% over the 10-month trial.

The host Banded Iron Formation (BIF) of the Shine iron mineralisation is sub-vertical and dips to the west at approximately -85. Holes are predominately drilled at an inclination of -55 and -60 towards both west and east due to the sub-vertical nature of the hosting unit. The Shine deposit is hosted within a north-south trending BIF.
