Is coal expensive to extract and mine?
It depends on the method of extraction. In pit mining, vertical shafts are dug to reach the coal seams, then excavated horizontally. The shafts and passageways need to be shored up or held in place to prevent collapse while the miners extract the coal. In open-cast mining, the surface is simply scraped away by huge excavators, and the coal loaded onto large trucks or long conveyor-belts for processing. Open-cast mining is cheaper - but requires more work to landscape the mining area once the coal is exhausted.
Extraction of sulfur by frasch process?
The Frasch process is a method to extract sulphur from underground deposits.Holes are drilled down through the overlying rock into the sulfur deposits. A series of concentric perforated pipes are then inserted into the drill hole. The outer pipes contain superheated steam (usually about 160 °C) which is pumped down into the deposit.Since the melting point of sulphur is so low (115.21 °C, just a little over the boiling point of water), it readily liquefies. As the sulphur becomes molten, it is removed by pumping air down the central pipe. When the molten sulphur reaches the surface, it is pumped onto wooden blocks where the sulphur again solidifies.The sulphur obtained by this method is 99.5% pure.
