A suitable process for clean coal recovery from tailing pond deposits
This study aims to recover fine coal process with efficiency at a very low reasonable investment and operational costs. In the present study, the sample was taken from a tailing pond of an operating coal preparation plant, cleaned using an enhanced gravity separator to produce a clean product of low ash content. The experimental results indicated that a good amount of clean coal recovered from tailing pond with an ash content of 16.24% could be produced from a feed of 33.5% ash with an appreciable yield of 69.15%. The multi-gravity separator (MGS) has an advantage of utilizing the fine- and ultrafine-sized refuse coal with minimum environmental pollution.
