    Energy Quality And Efficiency Of An Open Pit Mine

    Oct 09, 2014 This paper presents a solution to energy quality problems in an open pit mine distribution system. Specifically, mine shovel operation is frequently disrupted by energy quality issues. A number of alternative approaches to deal with this problem include the use of reactive power compensator technologies (i.e. passive filters electronically switched capacitor banks and static VAR compensators ...

    Mining And Mineral Processing Industries

    Mining companies are adapting their strategy to address energy costs and regulations requiring a quota of renewable sources from energy generators. Energy use in mining and mineral processing is strongly dependent on the ore quality and ore composition. The energy requirements for open-pit mining are different to underground mining.


    11 Phases Of A Mining Project Elaw Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
