LeadZinc ores

LeadZinc ores

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 collectors used in sphalerite flotation tend to be less powerful because sphalerite at this stage typically readily floats and using a more aggressive collector can float more nonsphalerite minerals.

Iron Ore Statistics and Information

Iron Ore Statistics and Information

Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel ...

Copper ores

Copper ores

A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range of silie minerals from quartz to talc and clays. Carbonate mineral gangue can also be present. When liberated ...

Mine Tailings

Mine Tailings

Mine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indied the tailings materials to be predominantly silt and fine to medium sand with <10% clay content.
