Flowchart Of Mine Extraction

Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding. The roasting process is meant to burn carbonaceous species trapped within the ore and make the ore more reactive to the leaching treatments.

Conveyor, and then bolting the mine roof in the excavated area. To provide a steady flow of coal in a room-and-pillar mine, several stages of mining occur simultaneously in different rooms. A final phase of mining termed retreat mining may be performed to recover additional coal by extracting pillars and allowing the roof to fall.

Coal Types Formation And Methods Of Mining

Most underground coal is mined by the room and pillar method, where by rooms are cut into the coal bed leaving a series of pillars, or columns of coal, to help support the mine roof and control the flow of air.Generally, rooms are 2,000 feet wide and the pillars up to 300 feet wide. At least 60 feet of coal was left between an underground mine and the surface, if not the surface had a higher.
