CopperSulfideFlotationCircuit. The pulp from the Conditioner is treated in a 10-cell“Sub-A”FlotationMachine and a 4-cell“Sub-A”Flotationmachine. Sometimes conditioners are not provided; however, their use insures that reagents are thoroughly mixed into the pulp ahead offlotation.

Flotationis both a science and an art. It brings together many complex variables. Such basic factors as knowledge of mineral structure, chemical reagents, pH of mill water, pulp density, temperature, technical skills of the operator, the dependability of theflotationmachine, as well as a host of other factors which affect theflotationof each specificoremust be combined to produce ...

Thecoarse particle flotation technologyis expected to play a key role in the company’s aim to ultimately eliminate tailings dams, according to AngloAmericanTechnical Director, Tony O’Neill. It should allow the company to coarsen grind size while maintaining recoveries – thereby reducing the energy required to grindore, as well as ...

Copperprocessing -Copperprocessing-Ores: Principal forms in whichcopperores are found include nativecopper, porphyrycopper, massive deposits, and mixed ores. Nativecopperis simply the metal found unadulterated in nature. Occasionallycopperis still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

With the depleting reserves of high-grade ironorein the world,froth flotationhas become increasingly important to process intermediate- and low-grade ironorein an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the ironoreindustry,froth flotationhas been established as an efficient method to remove impurities from ironore.

Theflotationbehaviour of low grade, coarse composite particles for two porphyrycopperores was studied. Different grinding times were employed to obtain size distributions for theflotationfeed (d 80) ranging from 150 to 320 μm.Coppercontaining particles in the fine to intermediate size ranges were recovered in the rougherflotationstage.
