Keywords : Gangue, Leaching, Coal mine ground water Impact on environment 1 INTRODUCTION During the process of coal mining, large amounts of solid wastes are produced, most of which are gangue. The amount of gangue is very large, at present, it is estimated that the amount is about 15 to 25 percent of raw coal.

The earliest use of iron in China DON WAGNER

The earliest use of iron in China. In these furnaces iron ores were used as a flux to reduce the melting point of the silica gangue of the copper ore. Much more iron ore than copper ore was used, and in normal operation the iron left the furnace harmlessly in the form of FeO in the slag. Zheng Shaozong (1956). `Rehe Xinglong faxian de

Pyrolysis and Combustion Behavior of Coal Gangue in O2/CO2

Combustion of coal gangue is extensively used for power generation in China. In this paper, pyrolysis and combustion characteristics of a lowrank coal gangue have been investigated under oxyfuel (O2/CO2) and air (N2/O2) conditions using a drop tube furnace and thermogravimetric analysis. Pyrolysis experiments were carried out in N2 and CO2 environments, which are the main diluting gases of
