Coal Beneficiation - Power Line Magazine

2017-7-9  An important aspect with regard to coal washing is the partial washing of non-coking coal. Under this, less than 13 mm particles are left unwashed and only over 13 mm coal are washed. The washed product (from +13 mm washing) is then blended with unwashed coal to obtain an overall ash content of 34 per cent in coal.
