Coal waste: handling, pollution impacts and utilization

01/01/2013· In the extraction of the valuable coal products, typically the production of 1 tonne of hard coal generates 0.4 tonne of extractive ‘waste material’, comprising waste rock including lost coal, and washery rejects and tailings, both containing economically recoverable coal. This chapter focuses on the situation in Poland and neighbouring coal-producing countries, describing efforts to recover this

Mine wastes management Mining and Blasting

Mine wastes management Mining wastes is generated during the process of extraction, beneficiation and processing of minerals. Extraction is the first phase that consists of the initial removal of ore from the earth. This is normally done by the process of blasting, which results in generation of large volume of waste (soil, debris and other material). This is useless for the industry and is normally just stored

Through the extraction and subsequent mineral processing, metals and metal compounds tend to become chemically more available, which can result in the generation of acid or alkaline drainage. Moreover, the management of tailings is an intrinsically risky activity, often involving residual processing chemicals and elevated levels of metals. In many cases tailings are stored on heaps or in large ponds,

Background. Burning coal produces a variety of solid wastes known as coal combustion waste or coal combustion products. These include coal ash (fly ash and bottom ash), boiler slag, and flue-gas desulphurization products. In 2007 over 120 million tons of these wastes were produced in the US, of which approximately 44% was reused in other applications.
