Air Tabling—A Dry Gravity Solid–Solid Separation

2015-1-1  Being a dry process, air tabling has a clear advantage over wet separation techniques because it does not require chemical pretreatment of the sample, treatment of water from the process for reuse or discharge, and most importantly, dewatering or drying the mixture after separation. Many factors affect the separation performance of air table.

Beneficiation of Fine Coal Using the Air Table

2019-2-22  The goal of this study was to develop a dry separation process for processing of coal finer than 6.3 mm (¼ inch). The coal sample from a mine located in Western Kentucky was used for the study. Statistical design experiments were conducted to assess the effects of operating parameters of the dry separator on product yield for a given ash content. Tests conducted with 6.3×3.35mm (and 3.35×1.4 mm size fractions showed that the air table was able to reduce the ash from 27% to 10-12% ash with a clean coal yield of 75-80%. The ash rejection was about 77-80% with a combustible recovery of around 95% indicating excellent separation efficiency. The pyritic sulfur rejection was 43%. The heat content of the 6.3×1.4 mm (1/4 ˝×14 mesh) coal
