Utilization of coal gangue for the production of brick

2016-6-8  Coal gangue, an industrial solid waste discarded from coal mining and processing, was used as the sole raw material to prepare brick. The coal gangue was crushed, homogenized, milled and then pressed into green compacts. The dried compacts were sintered at different temperatures for 2 h. The obtained brick samples were characterized with X-ray diffraction,

Comprehensive utilization and environmental risks of coal

2019-12-1  The production process of cement using coal gangue as raw material is similar to that of clay. The coal gangue is first activated and then ground in proportion to the quicklime and seed crystals. After the grinding, the mixture is hydrothermally synthesized and calcined at a low temperature to form a cement mineral (Liu and Zhou, 2007).

Direct reduced iron process - tec-science

2018-6-21  In contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to 1000 °C. The iron ores are therefore not melted! This also applies to the gangue contained in the ore, which is why the iron ores used must be relatively low in gangue from the outset. The reduction gases only dissolve oxygen from the ...
