Lead Zinc Separation by Flotation - Froth Flotation ...

Some of the metals that can do the job are copper and lead. At a pH between 8-9 lead can activate sphalerite to cause it flotation. So the reason is during the flotation of the two there may be lead re dissolution from galena which may activate sphalerite to cause it flotation. It may best if you are doing bulk flotation of the two.

Galena - Sphalerite Flotation Separation Method

2016-04-23  The tailing of the lead flotation stage passes direct, or, as explained above, through a thickener, to the zinc conditioner, where copper sulphate is added to activate the zinc minerals. Lime is generally introduced at this point to depress pyrite and to maintain the alkalinity of the pulp at the required pH value, usually between 8.0 and 9.0.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. ... His "Bradford Ore Separator," patented 1853 and subsequently improved, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process. The 1886 patent was to capture this "float" using surface tension, the first of ...

The copper ions replace zinc atoms on the sphalerite surface creating a pseudocopper mineral surface coverage on the sphalerite which is then collected using copper flotation type collectors. Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for iron sulphide depression. The flotation ...
