1. Comparative evaluation between mechanical and pneumatic cells for quartz flotation in the iron ore industry
Abstract Flotation plays a relevant role in the concentration of iron ores. Conventional flotation technology employing mechanical machines and columns and also circuits combining both types of cells have been utilized in the iron ore industry. The top size of particles in the flotation circuit feed is 150 µm and the slimes below 10 µm are removed as overf

2. SEM study of a lead-iron slag flotation process
Abstract Companies producing lead-acid batteries are required by law to recycle their battery scrap. The recycling can be performed by a pyrometallurgical process resulting in slags containing mainly lead and iron. A study was carried out with the aim of recovering the lead contained in this slag. This work has economic and environmental implications. Slag c

3. Mecanismo de flotação de partículas grossas em células mecânicas: influência das variáveis hidrodinâmicas e suas implicações cinéticas. / Mechanisms of coarse particle flotation in mechanical cell: influence of the hydrodynamic parameters and kinetics involvement.
A seletividade e eficiência do processo de flotação não estão fundamentadas tão somente nas diferenças das propriedades físico-químicas das superfícies dos minerais, mas também na hidrodinâmica do sistema de concentração. Via de regra, a eficácia da flotação diminui quando o tamanho de partícula ultrapassa 150 micrômetros. Esta pesquisa vi

4. Coarse particle suspension in mechanical flotation cells. / Suspensão de partículas grossas em células mecânicas de flotação.
Several attempts to correlate particle size and flotation response at the biggest Brazilian plants (iron ore and phosphate) have concluded that coarse particles (dp 100m) do not float efficiently. As solids suspension is a necessary precondition for particle collection, the study of coarse particle suspension in mechanical cells is fully justified and it is

5. DENSITY-GRADIENT PATTERNS OF STAPHYLOCOCCUS AUREUS CELLS AND CELL WALLS DURING GROWTH AND MECHANICAL DISRUPTION
Huff, Eskin (National Institute of Allergy and Infectious Diseases, Bethesda, Md.), Harriet Oxley, and Carol S. Silverman. Density-gradient patterns of Staphylococcus aureus cells and cell walls during growth and mechanical disruption. J. Bacteriol. 88:1155–1162. 1964.—Procedures capable of rapid disruption of Staphylococcus aureus cells with optimal rel
