Dec 17, 2016 · 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-correlated.

process of open pit iron mining

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. get price
