oee formula for iron ore mining

Mine production index (MPI)-extension of OEE for ...

2016-9-1  OEE has been used in many industries as a point of reference to measure the performance. However for mining industry the traditional OEE cannot be used as it is. The limitation of OEE as a metric for mining industry is explained further following terms. Quality parameter in traditional OEE is ratio of processed pieces and defective pieces.

25.2 Extracting ores Mining of mineral resources Siyavula

The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal. The balanced chemical equation for the reaction is:

Basically, the mining method used solely depends on the ore deposit that is mined, the location of the mining area, whether underground or on the surface, and also if the resource is feasible enough to start a mining project in the first place. Running a mining business should be run efficiently and responsibly, with every move managed properly.
