Effect of Desliming on Flotation Response of Kansanshi

The minimum copper feed grade for the mixed copper ore was % Total Copper (TCu). The outcome of this work has shown that desliming improves the flotation response of the Kansanshi mixed copper ore. At a rougher copper concentrate grade of 8%, copper metal recoveries obtained with desliming were in excess of 70% compared to 58% achieved with baseline tests …

Froth Flotation Circuit Design And Basic Testwork

Cleaner flotation tailings is an intermediate product and is recycled within the flotation circuit. Many ores contain multiple valuable minerals that can be floated into separate concentrates. Examples would include a lead-zinc ore, in which the lead and zinc minerals are recovered sequentially into separate concentrates. Another example would be a copper-molybdenum …

Primary Copper Smelting

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions

DEVELOPMENT OF A FLOWSHEET FOR THE ROVER GOLD COPPER

The ore is amenable to gravity gold with recovery ranging from 50% to 60%. Conventional tabling of the concentrate is required rather than intensive leaching because of the negative impacts of cyanide on flotation. A bulk flotation to recover copper, bismuth and cobalt is the best option rather than selective staged flotation. The copper and cobalt concentrate will be …

Effect of Desliming on Flotation Response of Kansanshi

improves the flotation response of the Kansanshi mixed copper ore. At a rougher copper concentrate grade of 8%, copper metal recoveries obtained with desliming were in excess of 70% compared to 58% achieved with base-line tests without desliming. It was further observed that desliming resulted in improved flotation rates for the sulfide minerals. For a flotation time of 3 …

Mount Isa Copper Mine, Queensland, Australia

Ore processing. The copper concentrator was rebuilt in 1973, with rod and ball milling and three-stage flotation, to supply the roaster and conventional blister copper smelter on site. In 1981, Mount Isa commenced anode casting as well. In 1988-1989, two AG/SAG grinding mills replaced the rod and ball mills at a cost of A$35m.

Pneumatic Flotation Challenges Conventional

Pneumatic Flotation Challenges Conventional Technology. A wide range of bubble sizes, online control of froth level, turbulence-free operation and no need for a blower or compressor comprise a user-friendly system. By Evren Ören, Lutz Markworth and John van der Heever. The Pneuflot pneumatic flotation system was introduced in 1987, with the

Controlled-potential sulphidization and rougher-cleaner

Previous results have shown how con- trolled-potential sulphidization (CPS) can give improved metallurgy during rougher flo- tation of mixed oxide-sulphide copper ores. Results in this paper, using different samples and different equipment, confirm the previous results and extend the application of CPS to cleaner flotation. By using CPS, faster flotation of copper minerals …

Chapter 12: Flotation of Copper Sulfide Ores

From a processing point of view, copper ores could be divided into: Copper sulfide ores, where the pyrite content can vary from 10% to 90%. The predominant sulfide mineral in this ore is pyrite, but may also contain pyrrhotite and mar-casite. Some copper sulfide ores also contain significant quantities of gold and silver.

Agglomeration–Flotation of Finely Ground Chalcopyrite

Abstract: Flotation is the conventional method for processing porphyry copper deposits, one of the most economically important sources of copper (Cu) worldwide. The rapidly decreasing grade of this type of Cu ore in recent years, however, presents serious problems with fine particle recovery using conventional flotation circuits. This low recovery could be attributed to the …
