In the present study, the flotation behavior of oxidized zinc ore from Angooran deposit, Iran was studied using several cationic, anionic and mixed (cationic/anionic) collectors by means of bench scale flotation studies. 2. Materials and Methods The oxidized zinc ore .
1). Flotation is a selective process and can be used to achieve specific separation from complex ores such as leadzinc, copperzinc, etc. Initially developed to treat the sulphides of copper, lead, and zinc, the field of flotation has now expanded to include the oxidized minerals, nonmetallic ores and fine coal. 2).
Laboratory batch flotation tests were conducted to determine the effect of two types of gasoilrinkalore mixtures on the flotation response of a copper cobalt oxide ore sample. The head assay conducted on the initial ore sample showed that it contained about % of Cu, % of Co.
This paper reviews uses of sodium sulfide in the flotation of oxide minerals of copper, lead, and zinc. The activation and depression effects of sodium sulfide are of particular importance because of their applications with oxidized lead and copper ores.
collectors. Selective flotation needs very careful control of conditions. Some examples are given below. (For more details see Gaudin "Flotation") Cu/Pb/Zn oxidised ores Ores contain Oxides, carbonates and even sulphates Treatment Problems Associated with the gangue minerals Oxidised and partially oxidised copper ores generally leached
May 24, 2019· The use of flotation conditioners process can increase the selectivity of the flotation process, enhance the effect of the collectors, and improve the conditions of the ore pulp. 1. Sulfurizing Reagent. Oxidized ore is generally formed by ionic bonding, and is highly hydrophilic. It is not easy to float oxidized ore with xanthate collector.
In this paper, the flotation behaviour of nickelcopper ores processed in the Sudbury area is discussed with emphasis on the effect of oxidation on individual minerals, primarily pyrrhotite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.
Apr 23, 2011· When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit. Supergene ores rich .
Dec 20, 2018· The vast majority of polymetallic sulphide ores containing gold and silver are treated by this method. When flotation of such ores, gold and silver enter into the copper concentrate or lead concentrate closely associated with them. The products are called copper, gold and silver concentrate or lead, gold and silver concentrate, etc.

The ores typically contain low percentages of copper and have to be concentrated by, for example, froth flotation before refining. Note: You will find a brief description of froth flotation on the introduction to metal extraction page.
Where oxidized minerals are a discernable issue, treatment options include flotation collector changes and sulphidization with either metabisulphide or SO2. Sulphide flotation of actual oxide copper minerals (such as malachite, azurite) is not possible with sulfhydryl mineral flotation collectors and either other oxide type collectors are required or alternative mineral beneficiation routes must be considered.
Sulfide minerals are oxidized at the surface and produce sulfuric acid, and acidified rainwater then carries the copper, as copper sulfate, down to the water table. Below the water table, where sulfide minerals remain unoxidized, any iron sulfide grains present will react with the copper sulfate solution, putting iron into solution and precipitating a copper mineral.
This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.

In this study, flotation of oxidised ores rich in copper and cobalt from Mupine deposit in the Democratic Republic of Congo had been investigated. This ore contains % copper, % cobalt. The recovery of copper and cobalt was performed using flotation to increase the concentration of copper and cobalt.

The effects of xanthates, dithiophosphates, dithiocarbamates and mixtures of these collectors on the froth flotation performance of partially oxidised and oxidised copper .
The recovery of oxide copper minerals from a complex copper ore by sulphidisation. Two potential ranges were investigated in this study; −300 to −400 mV and −400 to −500 mV. Optimum flotation performance was observed in the potential range of −300 to .
