Method Extracting Ore

Jul 06, 2016nbsp018332This method is substantially more efficient than the commonly used room and pillar tactic in which mined material is extracted across a horizontal plane, recovering up to 90 percent of the available ores. By contrast, room and pillar mining typically recovers 50 percent. Processing
