A process for separating molybdenite from copper concentrates containing copper and iron sulfides, gangue materials and an organic collector comprising (1) conditioning the concentrate in aqueous suspension at a pH below about 7 with a soluble metal salt; (2) contacting the so treated concentrate with hydrogen peroxide at pH of about 4 to about 8; (3) subjecting the concentrate from (2) to a ...

En presencia de caolinita y cuarzo se tiene mayor espumación con OrePrep R F-549 que con MIBC, mientras que lo contrario ocurre en presencia de montmorillonita. Este simple ejemplo muestra por sí sólo que los distintos tipos de arcillas afectan en forma diferente el proceso de espumación, y a su vez que los distintos tipos de espumantes ...

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form amodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt ...

An analysis of flotation in the absence and presence of collector is presented. Both single mineral and ore studies are dealt with, considering flotation data and correlating these with electrochemical studies, as well as solution and surface spectroscopic investigations. The multiple action of collector molecules is exposed.
