Beneficiation of Fine Coal Using the Air Table

2019-2-22million tonnes per year of coal. Dry coal cleaning techniques can be divided into three groups; air table, air jig and dry dense medium separator. Air table and air jigs were used to clean the coal. However, by 1985 the coal processing using these methods dramatically dropped to less than 7 million tons per year [5].

Development of dry coal gravity separation

Dry separation method was used at the beginning of 20 th century to separate coal separation process. First industrial applications of dry separation took place in the middle of 1930s. At that time air separator Frazer-Yankey, based on aero suspension was used in in Pittsburgh and Lundale, West Wirginia coal preparation plants.Get price
