underground mining flow chart

Aug 26, 2015 This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted

Copper Mining Process Flow Chart

Copper Mining Process Flow Chart. In copper mining process flow sheet, the copper ore deposit will be first extracted by open pit quarrying or underground mining methods. The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher

Underground mining – block caving, bore hole, drift fill

Retreat mining is a process that recovers the supporting coal pillars, working from the back of the mine towards the entrance, hence the word retreat.Room and pillar mining advances inward, away from the entrance of the mine. Other underground mining methods include Hard rock mining, bore hole mining, drift and fill mining, long hole slope

From 1890 to 1920, underground mining of graphite was practiced in New York and Pennsylvania. From 1942 until the end of World War II, only open-pit methods were used, because working weathered rock

Appendix E: Coal Mining and Processing Methods | Coal

Underground mining is usually by the room-and-pillar mining or longwall mining method . Even in mines where the longwall method is the principal extraction method, the development of the mine and the longwall panels is accomplished by room-and-pillar continuous mining. The thickness of the coal seam, the depth and inclination of the coal seam
