The concentration of pyrite is 17.2% and the concentration of non-sulphides is 10.6%. First, let's define our variables: Let x = mass of chalcopyrite (CuFeS₂) Let y = mass of pyrite (FeS₂) Let z = mass of non-sulphides. We know that the total mass is (or 1 if we're using decimal form), so: x + y + z = 1. Now, let's consider the Cu ...

Thereafter, the specified concentration of collectors (SIBX, DTC and MDPE) and frother were added in sequence for 2 min and 1 min. ... The sample preparation method measured by XPS measurements was ...
Understanding Copper Pyrites: Copper pyrites, also known as chalcopyrite, has the formula CuFeS 2. It contains copper, iron, and sulfur. 2. Concentration of Ore: ... The method is based on the principle that copper has a lower affinity for oxygen than for sulfur at high temperatures. This allows for the selective reduction of copper from its ...
The extraction of copper from copper pyrites involves several steps. First, the ore must be crushed into a fine powder to increase surface area and allow for easier extraction of the metal. Once this has been accomplished, …
Copper pyrite (Cu 2 S) is the ore of copper in the sulphide form so here method of froth-floatation should be used for concentration. 2 S) is the ore of copper in the sulphide form so here method of froth-floatation should be used for concentration.
Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method …
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of …
(i) froth floatation: This method is commonly used to concentrate sulphide ores such as galena (PbS), zinc blende (ZnS) etc. In this method, the metallic ore particles which are preferentially wetted by oil can be separated from gangue. In this method, the crushed ore is suspended in water and mixed with frothing agent such as pine oil, eucalyptus oil etc. A small quantity of …
The fact that the amount of iron dissolved is 5.4% (Fig. 2) indicates that approximately 1.1 g of pyrite reacted during the exothermic reaction (the mass corresponding …
Which of the following method used for the concentration of copper pyrites?
Extraction of copper from copper pyrite (C u F e S 2) involves : crushing followed by concentration of the ore by froth-flotation; removal of iron as slag; self-reduction step to produce 'blister copper' following evolution of S O 2; …
Why is froth-floatation used as the method of concentration for copper-pyrites ore? Q. Froth floatation process used for the concentration of sulphide ore: Q. Froth floatation process is used for the concentration of the ore of: Q.
Magnetic separation is used in the concentration of: Copper pyrites, Chromite, Bauxite, Cinnabar. ... Find th number of ores, which can be concentrated by magnetic separation method. Galena, Copper pyrites,Haematite,Siderate. View Solution. Leaching is a process of concentration of ores. Explain the leaching of alumina from bauxite.
Copper is extracted from its principle ore Copper pyrites C u F e S 2 . The ore is concentrated by froth flotation process. The ore is concentrated by froth flotation process. The concentrated ore is then roasted in a furnace where reactions remove sulphur and Arsenic gases-

The principle ore of copper is copper pyrite and copper is extracted from this ore. ... Crushing and Concentration: The ore ... It is mostly purified by electrolytic method.
Example.—Twenty grams of copper pyrites, known to contain 27.6 per cent, of copper, gave by the method first described 5.22 grams of copper, equalling 26 1/8- per cent. ... In the method of concentration by …
The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and concentration: The ore …
This study evaluated the effectiveness of using high pH to depress high-concentration pyrite in copper flotation with the performance compared to the depression of …
Chemical leaching is useful in the concentration of bauxite. Froth floatation method is used for copper pyrites. Hydraulic Separation method depends upon the differences in the gravity of mineral and gangue. This method is used for separating cassiterite from gangue.
Raising pulp pH is a common method for pyrite depression when pyrite concentration in flotation feeds is low. Whether raising pulp pH can effectively depress high-concentration pyrite in copper flotation remained unanswered. Hence, this research examined the effect of grinding and flotation pH on copper flotation with a high pyrite concentration.
