With the depleting reserves of high grade iron ore in the world, froth flotation . to reverse cationic flotation, and the rising of reverse anionic flotation in China in . as flotation, gravity concentration, magnetic separation have been employed in.
So, according to the practical production in a ore dressing plant, proposed the scheme of intelligent control for flotation reagent adding. This scheme on the basis of rough set theory, and comprehensive utilization the information and data of area, realize the reasonable control rules for reagent adding.
Comparative studies of reverse cationic/anionic Abstract. The comparative studies of reverse cationic/anionic flotation routes were conducted using Vale iron ore in batch scale flotation tests.
flotation (Ge at al., 2012). In terms of anionic collectors, Miller (2001) added polyethylene oxide (molecular weight 1000–8000) to an anionic collector to float the Florida phosphate ore. It was demonstrated that for a comparable phosphate recovery, the collector amount could be reduced significantly (~50% reduction) in the presence
A new silicate removal process strengthening pulp dispersion and cationic reverse was used on the basis of feature of the simple intergrowth relation of limonite ores in a Limonite Mine of Guangdong Province. 1250 g/t sodium carbonate and 600 g/t sodium silicate were used as .
A number of experiments were conducted to determine the flotation characteristics of Iowa coals in which various conditions were applied to study the effect of .
The research was carried out while maintaining uniform material preparation procedures. During a single experimental study one concentrate and tailings were obtained. The flotation products were dried and weighed and subjected to Xray fluorescence to determine the copper content.

studies, so it appears that the flotation properties of various mica minerals are similar [8]. Extensive research work was carried out by a number of researchers [2, 3, 29, 30] to study the separation process of mica from other silicate minerals using either anionic or .
Subsequently, two mechanism models were proposed to qualitatively establish the interaction relationship among algae, surfactants and bubbles in the flotation.
aggregated with iron particles. Reverse flotation using cationic, anionic collectors and their combination also were investigated. The multistage separation processes were designed and compared and the best process with less metal loss for impurity removal was established based on experimental results. 2. Experiment Sample Preparation
This paper investigates the effectiveness of froth flotation to remove copper and other heavy metals from dredged anoxic sediments (<250 μm) using a lab scale flotation cell with a selected anionic sediment fraction selected for flotation tests was potentially contaminated with a copper concentration of about 1763 mg/kg.

AT THE UNIVERSITY OF UTAH 192629. Using a 50gram miniature flotation cell devised by Gates and Jacobson in the Bureau of Mines at the University of Utah, Gaudin and his colleagues conducted systematic flotation experiments on 100 x 600 mesh highpurity mineral samples with highpurity reagents and distilled water.
Flotation of iron ore is performed in order to reduce the amount of certain elements, such as phosphorous, in the concentrate to an acceptable level for iron production. Phosphorouscontaining minerals, like apatite, associated with the iron ore are separated by reverse flotation using anionic carboxylate surfactants [2].
