Considerations on the kinetics of froth flotation of ultrafine coal contained in tailings
(Taylor & Francis Inc, 2009)
This article presents a kinetic evaluation of froth flotation of ultrafine coal contained in the tailings from a Colombian coal preparation plant. The plant utilizes a dense-medium cyclones and spirals circuit. The tailings ...
Use of a fluidized bed combustor and thermogravimetric analyzer for the study of coal ignition temperature
(2017-01-01)
Ignition experiments with two bituminous coals were carried out in an atmospheric bubbling fluidized bed combustor (FBC) and a thermogravimetric analyzer (TGA). In the FBC tests, the rapid increase in O2, CO2, and ...
Atmospheric bubbling fluidized bed combustion: Application to high ash coals and approach to scientific research
(1996-06-01)
This work is concerned with research on atmospheric bubbling fluidized bed combustion (AFBC) applied to mineral coals of high ash content. Coals is considered in a scenario of power generation both domestic and world-wide, ...
A thermogravimetric analysis of the combustion of a Brazilian mineral coal
(Sociedade Brasileira de Química, 2008)
Knowledge of coal combustion kinetics is crucial for burner design. This work aims to contribute on this issue by determining the kinetics of a particular Brazilian bituminous coal. Non-isothermal thermogravimetry was ...
Froth flotation of coal tailings
(ESCOLA DE MINAS, 2009)
The processes involved in coal preparation produce harmful effects for the environment, mainly by the quantity and nature Of wastes that are generated, These tailings generally called ""pyritic"", even though not presenting ...
Geological Characteristics of Unconventional Gas in Coal Measure of Upper Paleozoic Coal Measures in Ordos Basin, China
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2016-01-01)
There are enormous resources of unconventional gas in coal measures in Ordos Basin. In order to study the geological characteristics of unconventional gas in coal Measures in Ordos Basin, we analyzed and summarized the ...
