Journal ArticleDOI
XPS study on the mechanism of starch-hematite surface chemical complexation
Gabriela F. Moreira,Elaynne Rohem Peçanha,Marisa Bezerra de Mello Monte,Laurindo de Salles Leal Filho,Fernando Stavale +4 more
TL;DR: In this paper, the surface chemistry of starch adsorbed onto hematite was investigated by means of X-ray photoelectron spectroscopy and Fourier transform infrared spectrographs.
Journal ArticleDOI
Characterisation of aliphatic chains in vacuum residues (VRs) of asphaltenes and resins using molecular modelling and FTIR techniques
Roberto Rodrigues Coelho,Ian Hovell,Marisa Bezerra de Mello Monte,Antonieta Middea,Andre Lopes de Souza +4 more
TL;DR: In this article, Fourier Transform Infrared Spectroscopy (FT-IR) spectra of alkyl-benzenes, obtained both experimentally and theoretically (by quantum mechanics modeling), were studied using a semi-empirical software AM1.
Journal ArticleDOI
On the fundamental aspects of apatite and quartz flotation using a Gram positive strain as a bioreagent
Antonio Gutiérrez Merma,Maurício Leonardo Torem,José Jonathan Vallejos Morán,Marisa Bezerra de Mello Monte +3 more
TL;DR: In this paper, the fundamental aspects of apatite and quartz flotation using Rhodococcus opacus bacteria as a bioreagent were investigated using a rotary shaker under specific conditions such as particle size, biomass concentration, pH solution and conditioning time.
Journal ArticleDOI
The influence of the oxidation state of pyrite and arsenopyrite on the flotation of an auriferous sulphide ore
Marisa Bezerra de Mello Monte,Achilles Junqueira Bourdot Dutra,C. R. F. Albuquerque,L. A. Tondo,Fernando Antonio Freitas Lins +4 more
TL;DR: In this article, the influence of the oxidation state of pyrite and arsenopyrite on the flotation of an auriferous sulphide ore was investigated by different techniques, including electrode, pulp potentials, DRIFT spectroscopy and microflotation tests.
Journal ArticleDOI
Selective flotation of gold from pyrite under oxidizing conditions
TL;DR: In this article, the use of hydrogen peroxide as an oxidizing agent in the selective flotation of gold from pyrite with potassium amyl xanthate was studied by contact angle and electrophoretic mobility measurements carried out under similar conditions.
