Mining of Iron Ores – IspatGuru
Mar 14, 2014 · The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
Open-pit mining - Wikipedia

Open Pit Mining - an overview | ScienceDirect Topics
An open pit mine is typically excavated with a series of benches to reach greater depths. Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and loaded onto dump trucks, which then …

The Mining Process – Waihi Gold
1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from …
Open-Pit Mining Definition | Anglo American
This step in the mining process is critical to ensuring the sustainability of the land for future use. First, waste dumps are contoured to flatten them out and stabilize them. If the ore contains sulfides, it is covered with a layer of clay to prevent rain and oxygen from oxidizing the sulfides into sulfuric acid, which is also known as acid mine drainage.
