2002-3-1 Precipitate flotationThis process is based on the formation of a precipitate of the ionic species, using a suitable reagent, and its subsequent removal by attachment to air bubbles to form a flotation “concentrate” (Huang and Liu, 1999, Lemlich, 1972). Depending on the metal solution concentration, the precipitation may proceed via metal hydroxide formation or as a salt with a suitable anion (sulfide,

The flotation stage was performed in a Denver D-12 cell. It was carried out under the following conditions: PSD from 60% to 80% under 200# (ASTM); pH = 8,0; 40 g/t of F-503 (collector) and 30 g/t of H-70 (froather). These operational conditions were suggested by the Process Engineering and Chemical Laboratory staff from the plant.

Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores. It relies on generating a population of bubbles of suitable size that can carry the hydrophobic target mineral (usually but not exclusively sulfide minerals) up to be recovered.

2021-1-21 The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...
