KEYWORDS: Dry beneficiation, coal, fluidized bed, ilmenite, sand, fine coal, medium 1. Introduction Coal is the main resource for electricity generation and indus-trial metallurgical applications in South Africa (De Korte 2010). Coal is a complex sedimentary rock that comprises both organic and inorganic matters. The separation of coal
Dry coal beneficiation with an air dense-medium fluidized bed is one of the dry coal processing methods that have proved to be efficient. In this study a (40 x 40x 60) cm air fluidized bed was employed for dry coal beneficiation tests. The effects of coal particles size and shape as well as the bed density on beneficiation process were assessed.

Coal Ash Recycling 3 sites mandated under 130A-309.216 (Ash Beneficiation Projects) By January 1, 2017, Duke must designate two facilities for the beneficiation project; A third site must be designated by July 1, 2017 •Each site must produce 300,000 tons per year •Beneficiation expected to supply product to the cement industry
Water scarcity, especially in arid coal rich countries, is therefore encouraging the development of dry coal beneficiation technologies. The use of a dense medium fluidised bed (DMFB) has received a great deal of consideration in recent years, specifically in China. The use of a DMFB on a large scale was mostly concentrated on the beneficiation ...
