Copper extraction - Wikipedia

Secondary sulfides – those formed by supergene secondary enrichment – are resistant (refractory) to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits. Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate of chalc…

Copper-Nickel ores - Danafloat

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small amount of sodium cyanide. Elevating the slurry temperature to 30-35 degrees C may improve the separation. …

The flotation of copper oxide ore includes direct flotation and indirect flotation. Direct flotation is mainly used to treat copper oxide ores with simple mineral composition and uncomplicated properties; indirect flotation is to sulfide copper oxide ores by adding sulphide agent, and then flotation with common sulphide flotation agent.

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle…

Copper ore density separations by float/sink in a dry sand ...

10/06/2013· The separation of copper ores by density using float/sink in a dry sand fluidised bed dense medium is reported for the first time. The separation point density and efficiency (probable errors) of float/sink density separations in the dry sand fluidised bed dense medium may be controlled by varying the amount of sands with different density and the air fluidisation velocity. Copper ores can be …

Copper | Geoscience Australia

The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60% copper. The …

In the case of copper–molybdenum separation, chalcopyrite (CuFeS 2) and molybdenite (MoS 2) are the main copper and molybdenum minerals found in complex sulfide ores. The natural hydrophobicity of molybdenite results from its layered crystal structure. In the case of chalcopyrite, once the mineral is rendered hydrophobic by a xanthate collector, its depression can be effectively achieved by ...

The ‘mineral dressing' industry (i.e. the concentration of valuable ore materials out of its unavoidable mix with unwanted solids) is a good example of the employment of a very wide range of separation equipment, for use once the mined material has been comminuted to the state where the individual particles are each largely composed of one or other of the component materials. Where this ...

This concentration is usually accomplished by dissolution of the element by hot water (hydrothermal ore deposits - gold, silver, lead), preferential crystallization from magmas (chromite deposits or pegmatites), surface weathering and leaching (aluminum, nickel, copper), or gravity separation of minerals during erosion (gold, diamonds, titanium). In the majority of cases there are only one or ...
