LAKOS industrial filtration is very effective in mining operation, removing sand and other solids and keeping water filtration systems running efficiently.
The selection of underground mining methods is primarily based on the geological/spatial setting of the deposit. Candidate methods can therefore be chosen and ranked based on estimated operational/capital costs, production rates, availability of labors and
Early Mining Methods: Tin streaming The earliest form of tin removal was by streaming, which was taking tin out of river valleys. This happened on a huge scale: moors like Bodmin and Dartmoor were worked a great deal from very early times.
