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.

:Crushing in Mineral ProcessingCrushing Value Test Procedure · Primary crushing happens when we take big rocks, even ones bigger than a meter, and make them into smaller bits. These bits are often between 150 and 200 mm. This step is very important. It makes the rocks smaller. This helps the next machines work better at crushing or grinding them.

Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2). When ore is first processed (typically close to the mine) it is crushed to gravel-sized chunks and then ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a concentrate.
