Correlação entre estado de dispersão, propriedades eletrocinéticas e flotabilidade de hematita
(Universidade Federal de Minas GeraisUFMG, 2013-02-28)
Studies aiming to improve the beneficiation of iron ores are highly relevant. The grade of the valuable mineral in the ores being mined is steadily decreasing. The lower grade ores require finer grinding. Iron oxides and ...
Coletores potencialmente seletivos na separação de apatita, calcita e dolomita
(Universidade Federal de Minas GeraisUFMG, 2013-03-27)
The growing need for food and agricultural growth motivate the expansion of fertilizer production. In Brazil, the phosphate ores occur associated with silicates and carbonates. The chemical similarity between apatite, ...
Biodepression of copper-activated pyrite with acidithiobacillus ferrooxidans in flotation with fresh and seawater
(MDPI, 2021)
Acidithiobacillus ferrooxidans has been shown to be a good depressant of pyrite in freshwater and seawater flotation. However, the effect of these bacteria over copper-activated pyrite has not been studied. At the industrial ...
Caracterização do óleo de patauá e utilização para obtenção de um reagente coletor para a flotação de minério fosfático
(Universidade Federal de Minas GeraisUFMG, 2017-02-17)
As food demand increases and biofuel use expands, the world phosphate rock production substantially rises. The igneous and sedimentary phosphate rocks are the major economic viable source of phosphorous, which majorly ...
Caracterização de espumantes com diferentes cadeias hidrocarbônicas e sua influência sobre a superfícideda hematita
(Universidade Federal de Minas GeraisUFMG, 2012-08-27)
In mineral industry Mining industry normally looks for optimization of reagents related to flotation of iron ore, focusing on to achieve a more sustainable consumption, which leads to a new generation of reagents that, ...
Caracterização, estudos fundamentais e flotação de minério de ferro goethítico
(Universidade Federal de Minas GeraisUFMG, 2014-06-22)
Dealing with low grade iron ores with complex mineralogy has become a day-to-day reality for the mineral industry. A good example is found in the case of hydrated iron ores, which are composed by the minerals haematite, ...
Effect of biosolids and their main components in the concentration of copper sulphide ores
(2014)
The copper mining industry in Chile and perhaps in other countries as well is faced with the challenge to implement the best practices in order to achieve a sustainable and more environmentfriendly growth. Relationships ...
Biodepression of pyrite using Acidithiobacillus ferrooxidans in seawater
(Elsevier, 2018)
In Cu-Mo deposits it is usual to find considerable amounts of pyrite (FeS2). When processing this kind of ore by flotation, pyrite is rejected using lime to increase the pH to alkaline conditions (pH similar to 10-12). In ...
