TACKLING IMPURITIES IN COPPER CONCENTRATES

Friedberg et. al. 2014). However, our interest is not limited to arsenic but extends to other impurities found in copper and nickel concentrates as well. One considers a “typical” copper concentrate as having about 25+% copper and some minor quantity of impurities, preferably rich in precious metals.

Copper extraction - Wikipedia

The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat. All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachatesolution, but this is a m

Copper extraction - Wikipedia

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite ...

Copper and the Copper-Base Alloys 16.10 Copper was undoubtedly the first useful metal to be employed by Man. In many countries it is found in small quantities in the metallic state and, being soft, it was readily shaped into ornaments and utensils. Moreover, many of the ores of copper can easily be reduced to the metal,

Copper processing - Roasting, smelting, and converting ...

Copper processing - Copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...

Energy and Environmental Profile of the U.S. Mining

The roasted ore leaves through the bottom brick hearth and sulfur dioxide (2-6 percent) exits through the top. Smelting – Smelting involves the application of heat to a charge of copper ore concentrate, scrap, and flux to fuse the ore and allow the separation of copper from iron and other impurities. The smelter furnace produces two separate ...

Lead ores are generally found as oxides or sulphides. Other impurities present in the ores are iron, copper and zinc etc. The prepared ore concentrate, together with the flux (lime and silica), is fed into a small blast furnace, where the temperature is raised to about 10100C. The lead is melted and a liquid slag formed of the impurities.

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
