Using float-sink data in simple equations to predict sulfur contents
(ELSEVIER SCIENCE BV, 2002)
In this study, the interpretation of float-sink test data by simple equations on coals of different origins with respect to sulfur content has been investigated. Primarily, the cumulative weight and sulfur content of the ...
The investigation of coal-pyrite/lignite concentration and their separation in the artificial mixture by oil agglomeration
(ELSEVIER SCI LTD, 2002)
In this study, the concentration of coal-pyrite and lignite taken from Yozoat-Ayridam (Turkey) Coal Management was investigated by oil agglomeration. In the previous studies, the agglomeration of coal-pyrite was investigated ...
Investigation of the effects of some operating parameters by using anionic and cationic flocculants for removing solid material in the lignite wastewaters
(MRS PUSHPA AGARWAL, 2002)
In this study, the effects of various operating parameters (pH, stirring rate, flocculant concentration. stirring time, flocculant feeding rate) on flocculation of lignite coal wastes were investigated, Experimental data ...
Determination of various flocculants' performance in flocculation of lignite waste pulps
(ASIAN JOURNAL OF CHEMISTRY, 2002)
In this study, the performance of the different flocculants, in the flocculation of the pulps prepared using lignite samples, has been investigated taking into consideration floc settling rate, supernatant turbidity and ...
Investigation of the effect of agglomeration time, pH and various salts on the cleaning of Zonguldak bituminous coal by oil agglomeration
(ELSEVIER SCI LTD, 2002)
In this study, the effects of bridging liquid concentration, agglomeration time, pH and various salts on the combustible recovery and ash contents of the agglomerated products have been investigated. Kerosene was used as ...
Nitrogen and phosphorus removal in lab-scale activated sludge systems
(MRS PUSHPA AGARWAL, 2002)
The phenomenon of anoxic phosphate uptake with simultaneous denitrification was studied. Experiments have been carried out with biological nutrient removal in a single sludge system by using the activated slude samples ...
The investigation of the floatability improvement of Yozgat Ayridam lignite using various collectors
(ELSEVIER SCI LTD, 2002)
In this study, the floatability of Yozgat Ayridam lignite using kerosene, kerosene + emulsifier and kerosene + emulsifier + surfactant has been investigated. It was determined that the combination of both kerosene + ...
