Handbook of Flotation Reagents: Chemistry, Theory and ...
represents a significant problem in the separation of copper from sphalerite. This
is because the secondary copper minerals are soluble and during grinding, or in
situ, they release copper ions, which activate sphalerite. It is quite common that ...

Froth Flotation: A Century of Innovation
upon the addition of copper salts, sphalerite readily responds to flotation with low
additions of short-chain xanthates. As discovered by Leslie Bradford in 1913 in
Australia, this means of enhancing the floatability of sphalerite has become the ...

Applied Mineralogy in the Mining Industry
Trout Lake ores 4.2.1.1. Massive sphalerite (MS) ore type The massive sphalerite
ore type occurs at the hanging wall of the ore lenses, and consists of semi-

Encyclopedia of Surface and Colloid Science
Zinc sulfate is used as a depressant for sphalerite in the selective flotation of lead
-zinc and copper-zinc ores. Its depressing action works only in alkaline pH. This
could be due to: 1) Zn(OH)2 precipitates or adsorbs on the sphalerite surface ...

Changing Scopes in Mineral Processing: Proceedings of the ...
Our examination of the influence of cyanideless depression on the surface
properties of galena and sphalerite was made under the important
environmentaly research of replacing toxic by nontoxic or less toxic reagents (
FeSO4-NaCN).

Indium: Geology, Mineralogy, and Economics
Indium substitution processes in sphalerite accounts for even higher enrichments
in most deposits. This indium enrichment in more complex, polymetallic ores is
related to the high-temperature introduction of indium, copper, and tin by diffusion
...

refractory character of sphalerite in solid state reactions (Barton 1 970).
Hutchinson and Scott (1980) observed that in many metamorphosed ores the
sphalerites, which were poikiloblastically encapsulated within metablastic pyrite,
appeared ...
