Recycling of thermal power plant bottom ashes
(2006)
Beneficiation of unburned carbon was conducted in order to increase the possibility of the recycling of coal fired power plant bottom ashes. Two stage flotation techniques were used for this study. In the flotation experiments ...
Contact angle measurements on lignite surface
(2010)
Froth flotation has been widely used for cleaning and desulfurisation of coals for many decades all over the world. There is a close relationship between floatability of minerals and contact angle. Therefore surface ...
The Utilization of Unsaleable Lignite Fines at Eskisehir Koyunagili Region Lignite Deposits
(Taylor & Francis Inc, 2012)
Samples taken from stock piles of Koyunagili Lignites Company preparation plant were cleaned by means of gravity methods to obtain a saleable product. The optimum conditions of separation were determined under the laboratory ...
Floatability of Eskisehir Koyunagili Region Lignite Fines
(Int Scientific Conference Sgem, 2010)
In this work, samples were taken from Koyunagili Lignites Company Washing Plant feed and were subjected to extensive research to determine the floatability of lignite fines. The optimum conditions of flotation were determined ...
Desulphurization of lignites by slow, fast, and flash pyrolysis and high intensity dry magnetic separation
(Taylor & Francis Inc, 2007)
Slow, fast and flash pyrolysis followed by high intensity dry magnetic ( HIDM) separation experiments were conducted to obtain improved solid fuels. Pyrolysis experiments were performed in three different apparatus, and ...
Evaluation of combined lignite cleaning processes, flotation and microbial treatment, and its modelling by Box Behnken methodology
(Elsevier Sci LTD, 2017)
In this study, first, the physicochemical cleaning of Cayirhan region's low-quality lignites was investigated by flotation to reduce ash content. In the flotation experiments, the effects of collector dosage, frother dosage, ...
Conversion of coal-fired bottom ash to fuel and construction materials
(Taylor & Francis LTD, 2017)
In this study, solid wastes taken from Seyitomer coal-fired power plant bottom ashes were subjected to experimental research to obtain a carbon-rich fraction. The possible recycling opportunities of remaining inorganic ...
Beneficiation of graphite fines from moulding factory wastes
(SAGE Publications LTD, 2005)
As the costs of waste disposal increase, more attention is being placed upon the re-use and recycling of valuable minerals contained within the waste streams. In this article, the waste streams from a moulding factory were ...
Isolation and characterization of native microorganism from Turkish lignite and usability at fungal desulphurization
(Elsevier Sci LTD, 2014)
In this study, microorganisms were isolated from Mihaliccik region (Eskisehir, Turkey) lignites with low rank and high ash and sulphur content. A series of heavy liquids (from 1.3 g/ml to 1.9 g/ml) were used to determine ...
Recycling of coal combustion wastes
(SAGE Publications LTD, 2009)
The separation of unburned carbon from coal-fired power plant bottom ashes was conducted in order to increase the possibility of the recycling of coal combustion wastes. A two-stage flotation technique was used for this ...
