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. 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

main gangue mineral for the three basic ore types [8]. Zinc oxide ores are much more difficult to be recovered by froth flotation than zinc sulfide good selectivity, and it chemisorbed on to niobite surfaces through its –P=O and –P–O– group. Zheng et al. [37] also found that 1hydroxyoctylidene1,1diphosphonic acid chemisorbed

May 17, 2019 · Abstract. The Muli antimony deposit is loed in the Au–Sb polymetallic metallogenic belt in southeastern Yunnan, China. In this paper, we investigated the concentrations of trace elements in gangue minerals, mainly calcite, quartz, and pyrite, which were formed at different metallogenic stages.
A review of entrainment: Mechanisms, contributing factors and modelling in flotation because they are commonly complex and valuable minerals are often associated with gangue minerals at even fine grain sizes. pulp settling effects and hence significant increases the ability to accurately predict gangue recovery by entrainment (Zheng et

The microstructure and mineral composition of the gangue play a decisive role in the precipitation of heavy metal elements. In this study, the microstructure, mineral composition, and precipitation of heavy metal elements of coal gangue with different weathering degrees were analyzed through electron microscopy, Xray diffraction, and static immersion leaching experiments.

The Sr analogue of aragonite and witherite pare olekminskite and ''UM198907CO:CaSr''. Strontianite, strontium carbonate, is mainly found as a lowtemperature mineral in limestone and also found as a gangue mineral in sulphide veins.
In this paper, a new method of vibration signal analysis of coal and gangue based on HilbertHuang transform is presented. Empirical mode decomposition algorithm was used to decompose the original vibration signal of coal and gangue into the intrinsic modes for further extract useful information contained in response signals under complied environment.

By 1650, Koxinga was strong enough to establish himself as the head of the Zheng family. He pledged allegiance to the only remaining claimant to the throne of the Ming Dynasty, the Yongli Emperor.The Yongli Emperor was fleeing from the Manchus in southwestern China with a motley court and hastily assembled army at the time.
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
Gangue as flame retardant was used to PVC, the mechanical properties and flame retardance of the samples were studied. The resultant data show that gangue little effect on the mechanical properties of the sample, especially tensile strength, yield stress, and 10% of gangue obtained good flame retardance. PVC treated with flameretardants showed a high limiting oxygen index, char yield, which

INTRODUCTION. Chromium compounds are essential to many industries, but their manufacturing process is usually a major source of pollution [14] the traditional manufacturing process that uses oxidation roasting at a high temperature (1200° C), water leaching and multistage evaporation crystallization [3, 4], the utilization efficiency of resources and energy is quite low.
