MINING: The mining of potash can be done by two methods, namely underground shaft mining and solution mining. Underground shaft mining involves digging underground tunnels to extract the potassium ores from the Earth's surface. The ores collected in the underground tunnels are transported to the surface either by manual labor or conveyor belts.
