Economic Impacts of Open Pit Mining Bizfluent

2017-9-26  Economic Impacts of Open Pit Mining. Believe it or not, mining and economics go hand in hand; they are both built on the premise of extracting a commodity at the lowest cost and selling at highest profits. Business processes for mining include physical design methods, scheduling collections, expelling and removal of waste materials from the pit.

Open Pit Mining - an overview ScienceDirect Topics

Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.
