Material of burned coal wastes spoil heaps as source of mullite for ceramic industry

Original language description

Burning or burnt out mine spoil heaps may be potential sources of materials not only for building purposes, but they may also be used in the ceramic industry. Decay of the coal mass contained in the mine spoil heaps often leads to self-ignition. As a consequence of spontaneous mine fire, which may approach 1600 oC, the surrounding waste rock undergoes thermal conversion. The temperature conditions inside the burning spoil heaps are analogous to the production conditions of refractory opening materials and fillers in rotary furnaces. The article deals with an analysis of anthropogenic porcelanites in terms of their phase composition and their possible application in the ceramic industry. The material under analysis underwent X-ray diffraction, electronmicroscopy and X-ray fluorescence to identify its chemistry and mineralogy. The article also proposes an enrichment method for the given material, through which a higher proportion of its useful component, mullite, may be obtained. Applyi
