The disintegration was accomplished by conditioning 250 grams of wastepaper, under moderate agitation, with hot steam (84 to 90 °C), de-ionized water and reagent as desired. After disintegration the pulp was further dispersed in a high speed blender. All pulping experiments were done at a

    1. Introduction. Flotation is widely applied in the mineral processing industry to recover valuable minerals from crude ores. In general, metallurgical performance of a flotation process depends mainly on the mineralogical nature of the ore being processed, the performance of the flotation cells, aeration and hydrodynamic conditions of the pulp in flotation cells, the particle size 12.3 Primary Copper Smelting. Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air

KEYWORDS Galvanic interaction, Grinding, Sphalerite, Surface chemistry, Copper/zinc separation Thus, to optimise flotation recovery and grade it is usually best to grind to a fine size. This requirement needs to be balanced by the cost of grinding finer and the revenue that results from an increase in grinding throughput, which often results in a coarsening of the flotation feed.

    Copper FlotationMineral Processing Metallurgy. The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation. Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
