Flotation of Oxide Copper and Copper Cobalt Ores 19 1 INTRODUCTION Flotation practice of oxide copper minerals dates back to almost 60 years ago and has been applied in Central Africa (Congo) by Union Miniere (Belgium) The process involves two basic flotation methods (a) fatty acid flotation of oxide copper minerals from siliceous ore Get price


12 3 Primary Copper Smelting

Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining 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 Get price


A Copper Oxide Ore Treatment by Flotation

The ore containing 0 77%copper the main metal minerals in the ore are hemesite pyrite bornite covellite malachite the main gangue minerals in the ore are quartzite dolomite plagioclase Chlorite calcite And the copper oxidation ratio of the ore is 45 5% According several flotation tests finally found that the optimum reagents dosage are butyl xanthate 90g/t as collector pine oil Get price



Copper-Cobalt ores Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals Cobalt depression can be enhanced by small cyanide dosages If the cobalt is found with chalcopyrite bulk flotation can be carried out with xanthate at pH 10 and separation madeGet price


COPPER Copper production

Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery for example heap leaching In Zambia and Zaire however siliceous copper oxide ores are floated with fatty acid collectors and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated [48] Get price


Copper Oxide

Flotation of Oxide Copper–Gold Ores Oxide copper–gold ores are usually accompanied by iron hydroxide slimes and various clay minerals There are several deposits of this ore type around the world some of which are located in Australia (Red Dome) Brazil (Igarape Bahia) and the Soviet Union (Kalima) Get price



Differential flotation sequence A differential copper-cobalt flotation separation which begins with selective copper flotation by raising the slurry pH to 10 with lime and using a dithiophosphate copper collector The tails produced in the first differential flotation step is followed by a pyrite and pyrrhotite flotation stage using xanthate Get price


Copper ore processing

Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation Also for some copper ore it is combined by both oxide copper ore and sulfide copper ore after processing test combined processing technologies can also be adopted to extract copper Get price


MEI Blog Challenges in copper flotation

Sep 10 2011There are a number of papers on copper flotation scheduled for Flotation '11 but two of particular interest to those involved with oxidised and oxide copper minerals will be given by workers from Australia who have found encouraging flotation response of malachite and chrysocolla using hydroxamate reagents Get price


Applications Copper Compounds

The metal industry uses large quantities of copper sulphate as an electrolyte in copper refining for copper coating steel wire prior to wire drawing and in various copper plating processes The mining industry employs it as an activator in the concentration by froth flotation Get price



improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged The flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a bench-scale testing regime TheGet price


Copper Mining and Processing Processing of Copper Ores

The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different chemistries of the ore Copper oxides are more abundant near the surface but are considered low-grade ore with a lower concentration of copper Get price


1 Froth Flotation – Fundamental Principles

For example if 20% of the water entering a flotation cell is carried into the froth then up to 20% of the fine particles entering the cell will be entrained The entrainment of coarser particles will be less than 20% due to their greater ability to drain from the froth Get price


oxide copper flotation

copper oxide ore flotation separation machine processing line Nov 07 20180183 32 Flotation is main method of copper ore beneficiation some are also using natural copper ore can be divided into sulfide ore (containing copper oxide smelting combined method or separation and flotation combined processing Get price


Studies of contact angles on oxidized copper minerals

In the concentration of copper ores by flotation the major loss of unrecovered mineral in the tailings is caused by the ineffective floata bility and recovery of the oxide copper minerals That the industry would benefit greatly ifmore of the oxide minerals were recovered is Get price


v117n8a11 The role of pulp potential and the

on flotation When oxide copper minerals are hosted in a matrix of acid-consuming gangue such as calcite acid leaching becomes an uneconomic processing option and froth flotation is the preferred process Where the oxides are chemically well defined as in theGet price


Response Surface Methodology for Optimization of Copper

The main copper oxide minerals in flotation tailings are malachite and chrysocolla and the main gangue minerals quartz and biotite are wrapped around the copper oxide minerals They are symbiotic with each other The proportion of copper oxide is relatively high (93 41%) Get price


Collahuasi Copper Mine

Sulphide ore is treated by flotation to produce concentrates for export The oxide circuit flowsheet involves both leaching to recover the contained copper and electro-winning to produce copper cathodes Handling copper cathodes in the electro-winning plant High-purity copper cathodes awaiting shipment at the electro-winning plant Get price

Water Requirements of the Copper Industry

About 41 percent of the water used was saline 70 percent of this saline water was surface water and the remaining 30 percent was ground water The total amount of water supplied to each flotation mill and the total production of copper during 1955 was obtained for each mill Get price


A Copper Oxide Ore Treatment by Flotation

The ore is the oxide ore of Copper lead and zinc The ore has high Oxidation rate of Pb nearly 50% which contains 3 56% of Pb 3 86% of Zn 0 209% of Cu The flotation flowsheet consisting of the scene is "Part of the mixed flotation—inhibitor Zn and Pb-Cu mix flotation—Zn flotationGet price


Cobalt processing

Cobalt oxide In the proportion of about 454 grams (1 pound) per ton of dry clay cobalt oxide is also employed to neutralize the iron colour in pottery sanitary ware and tiles and in larger quantities to add blue colour A rich blue is obtained by adding 5 percent cobalt oxide to a glaze of high lead content Get price
