The dry coal processing using air table was commercially introduced as early as 1916 in the USA and was quite popular for the next 50 years, reaching its peak in 1965 processing more than 25 million tonnes per year of coal. Dry coal cleaning techniques can be divided into three groups; air table, air jig and dry dense medium separator.
