Mining and milling
· Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with frontend loaders and loaded onto dump trucks, which then transport the ore to a milling facility.
Appendix C. Example Problem, Open Pit Mine, CIP Mill
APPENDIX C. EXAMPLE PROBLEM, OPEN PIT MINE, CIP MILL. The following example demonstrates how to apply the large open pit mine, CIP mill, and tailings pond equations. An example of mine life, capacity, and underground equations is in appendix D. Assume a SR of 2:1, 10,000 st/d ore, 20,000 st/d waste, for a total of st/d of material mined per day, 260 d/yr. Milling is 350 d/yr, so the ...

Selection of practical bench height in open pit mining ...
In open pit mining, factors that can affect the degree of dilution can be regarded as depositrelated or minerelated. The bench height is a minerelated parameter that can be studied using a simple geometrical model of the deposit. By changing this parameter individually, while the depositrelated parameters (such as ore distribution, ore slope and ore thickness), and minerelated parameters ...
