Get PriceApr 30, 2008 This investigation has been carried out to study the flotation characteristics of oxidised Indian high ash sub-bituminous coal having particle size below 1 mm. Initially the flotation study was carried out using conventional reagents only in a Denver D-12 sub-aeration flotation cell.
Get PriceApr 01, 2014 Reuse options for coal fly ash and coal bottom ash are reviewed in this paper. Although, significant quantities of coal fly ash and coal bottom ash are produced worldwide every year, less than 30 of coal ash produced is reused. Coal ash is mainly reused in civil engineering applications such as road construction, embankments, construction materials, geo-polymer applications and in cement ...
Get PriceNov 03, 2014 In case of an average bituminous coal, it is generally considered that the danger of sp. combustion is slight for sizes larger than 38mm. d. Freshness of exposed coal surface For any given set of constant conditions, the rate of oxidation of exposed fresh surface of coal decreases continuously during the progress of oxidation, that is ...

Get PriceUnderground coal mining in western China causes heavy land subsidence and alters the soil ecology. However, the effects of land subsidence on soil fertility are not currently known, and the key factors governing its impact remain unclear in sandy land. We investigated the effects of land subsidence induced by underground mining on the soil quality in western China.
Get PriceThe use of raw bituminous coal instead of coke or anthracite Introduced some coal constituents into the tars and waste liquids of CWG plants. Coke and anthracite coals have very low volatile contents, and tar acids phenols, tar bases, and cyanides were pro- duced in only trace amounts from CWG when these generator fuels were used.
Get PriceThe Williston Basin of North Dakota is estimated to contain more than 530 billion tons of sub-bituminous and lignite coal. Calculations based upon these volumes, and gas-sorption values from nearby biogenic methane producing basins yield in-place methane gas reserve estimates of greater than 13TCF.
Get PriceThe present study evaluates the CBM potential of Indian bituminoussub-bituminous coal reserves using Kims correlation and further ests. the CO2 sequestration capacity of coal seams. These data are useful to the industries, which are aiming at the CBM resources of India.

Get PriceThe effects of CaO under normal pressure and CaO soaked in ammonia on the isothermal gasification of Jinjie bituminous coal char-CO 2 are studied on the self-built fixed-bed experimental bench with analytical pure CaO as the precursor. The experimental results show that the gasification activity of Jinjie coal char increases with the increase ...
