Mining iron ore is a high-volume, low-margin business, as the value of iron is significantly lower than base metals. It is highly capital intensive, and requires significant investment in infrastructure such as rail in order to transport the ore from the mine to a freight ship. For these reasons, iron ore production is concentrated in the hands ...

critical to evaluating the impact of blasting on the entire Thabazimbi mining operation. Waste mining constitutes the major part of the operation with a stripping ratio of around 10:1, and as such is a key area to improving efficiencies. This research focuses only on the waste mining component with ore mining to be considered at a later date.
Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.
It is common in mining industry that the deposits contain multiple correlated attributes of interest. A typical example is iron ore mining, where up to six variables need to be considered in resource estimation and mine planning, namely iron (Fe), silica (SiO 2), alumina (Al 2 O 3), phosphor (P), loss on ignition (LOI) and Ochreous Goethite (GOL), and they are cross …
Exploration and evaluation consist of identification and quantification of ore bodies by using a range of geological, geophysical and metallurgical techniques. In its simplest forms exploration involves drilling in remote areas to sample areas. The data from exploration activities is logged, mapped, analyzed and interpreted often by using models.

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start.
