Coarse-particle flotation applied to copper sulfide ores

The largest source of copper supply worldwide comes from copper produced through flotation processes. It is estimated that more than 82% of primary copper production comes from concentration by flotation processes. In Peru, the latest mining megaprojects have been concentrator plants (Cerro Verde, Las Bambas, Constancia, Antapaccay, and so on).

The role of pulp chemistry in the flotation recovery

Cobalt ore is mined from the open pit at a grade of 1.30-1.80% Cu and 0.20-0.80% Co. The copper ore is a complex mixture of sulphide and oxide minerals and processing consists of sulphide flotation followed by sulphidisation and an oxide flotation step. The work reported in this study involves that ofthe underground copper ore only.

Mining Industry Copper Sulfide Ore and

3 Summary of the copper mineral flotation process (1) Copper minerals (such as chalcopyrite and covellite) that do not contain iron are similar in floatability. Cyanide and lime have weaker inhibition on them, so a large amount of lime can be added to inhibit pyrite in the separation of copper and sulfur without seriously affecting the floatability of copper minerals.

Chapter 6 Copper Production Technology

Froth flo- tation is the prevalent concentration method in the copper industry; it separates the pulverized ore (containing around 0.6 to 2.0 percent cop- per) into concentrates (with 20 to 30 percent cop- per) plus tailings (wastes of 0.05 to 0.1 percent copper) .40.

Palabora Mining Company Ltd

Secondary milling has been applied since 2003 by reconfiguring existing equipment. This is to improve liberation and recovery of copper on higher grade underground ore. Chemicals are added to allow the copper sulphide particles to separate from the fine ore particles through a process of 'froth flotation'.

Conditions Contributing to Underground Copper

Mitigating the Underground Corrosion of Copper. The underground corrosion of copper can be effectively mitigated by a number of techniques. These include: cathodic protection, improved drainage, avoidance of nonhomogeneous and cinder backfills, judicious use of selective nonaggressive backf ills, proper system design and industry standard workmanship, and

Top 10 active copper mines in Canada Mining &

Using autogenous and semi-autogenous grinding and flotation methods, the Highland Valley Copper Mine is the largest open-pit facility of its kind in Canada (and one of the largest in the world). According to the Teck website, plans are in the works to further explore this area in hopes of extending the life of the mine by finding more mineral deposits.

How to Prevent Corrosion of Copper Tube in

Other factors that could promote underground corrosion of copper include: Oxygen differential concentration cells. Preferential corrosion is sometimes found on the underside of copper tubes because they are in contact with undisturbed soil where the oxygen content is reduced, in contrast to the upper portion of the tube which may be exposed to aerated backfill where oxygen content is high.

Froth flotation Wikipedia

The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded (purified) by flotation technology. [citation needed] Prior to 1907, nearly all the copper mined in the US came from underground vein deposits, averaging 2.5 percent copper.

Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine.
