Avaliação em escala piloto do comportamento dos produtos pellet feed, pellet screenings e micro pellet em substituição ao sinter feed em uma mistura de sinterização
(Universidade Federal de Minas GeraisUFMG, 2004-06-02)
Pilot scale sintering experiments were performed, aiming at comparing the quality of the sinter produced from a reference sintering blend with that of sinters resulting from other blends, in which the sinter feed in the ...
Produção de sínter com pellet screenings e pellet feed com emprego de granulação intensiva
(Universidade Federal de Minas GeraisUFMG, 2015-11-27)
Pilot sintering tests were performed in order to compare production parameters and quality of sinters produced based on Western Europe and Asia standard mixtures, with sinters produced from the addition of Samarcos pellet ...
The response of meiofauna and microphytobenthos to engineering effects of fiddler crabs on a subtropical intertidal sandflat
(2016-08-01)
Fiddler crabs are key bioturbators on tidal flats. During their intense bioturbation process, they manipulate large amounts of sediment, altering the physical state of existing materials. We investigated whether different ...
Avaliação de pellet feed de diferentes superfícies específicas como alternativa de matéria-prima para a sinterização de minério de ferro
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2019-12-06)
Recently, with the increase of the demand for iron ore and the depletion of high grade ore deposits, the main mining companies around the world have been investing to increase the use of low grade iron rocks, known as ...
Avaliação do efeito da adição do pellet, umidade e cal, nos parâmetros de uma sinterização piloto
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de Minas - Mestrado ProfissionalUFMG, 2019-12-16)
The pellet feed addition in conventional sintering has become a common practice due to the increased sinter feed silica content, requiring adjustments to the sintering process routes. With the acquisition of the intensive ...
Utilização de maiores percentuais de pellet feed na etapa de aglomeração a frio da sinterização de minério de ferro a partir da adição de aglomerantes
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2019-07-09)
The sintering process is the main producer of agglomerated iron burden for the blast furnace. The world tendency on the reduction of high quality iron ore availability, leading to an increase of ultra-fines production, and ...
SEDIMENT BIOTURBATION POTENTIAL of UCA RAPAX and UCA URUGUAYENSIS AS A RESULT of THEIR FEEDING ACTIVITY
(Crustacean Soc, 2012-03-01)
Bioturbation of mangrove sediments by Uca uruguayensis (Nobili, 1901) and U. rapax (Smith, 1870) was compared based on the grain-size composition and organic content in surface sediment around the burrow and feeding pellets ...
