    2011-09-17 · However many other minerals respond poorly to flotation, and may even impede the flotation of readily floatable minerals, as at Palabora in South Africa, where the ore contains small amounts of valleriite, a copper-iron sulphide containing Mg and Al groups in the crystal lattice, and occurring intergrown with other sulphide minerals. Valleriite has a low flotation response, and it is a .

    Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide ...

    Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.
