Abstract. Clay is defined as a natural, earthy, fine-grained material, largely of a group of crystalline hydrous silicate minerals known as clay minerals. The usual types of mines are open pit but underground mining is also done for clay, associated with coal deposits and more profitable, particularly for fire clays.

The effect of mineralogy and texture on the beneficiation of goethitic ores from two different origins is highlighted. Sample A having 54.47% Fe with 8.57% loss of ignition (LOI) indicates the presence of vitreous and ochreous goethite, martite and microplaty hematite as the major minerals. Sample B contains 56.90% Fe with 14.4% LOI.

(Ragnarsdottir et al., 2011) - and the losses incurred at the mining and beneficiation stages (Scholz and Wellmer, 2015). Nonetheless, technological …

The advent of low-quality export coal demand has brought a new range of possibilities to the South African coal industry. Products that traditionally were only of value to the domestic or combustion industry sectors now have the potential to be

OF A LOW GRADE ORE FROM VITI LEVU, FIJI By M. H. BUCKENHAM, Faculty of Technology, University of Otago. (Received for publication, 10 November 1%0) Summary Because of the increasing demand for manganese and the depletion of high-grade deposits considerable attention is now being directed at beneficiation of low-grade manganese …

Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve …

The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …
