The Flotation Process Until quite recently copper ore had to be handpicked if the extraction of the metal was to be economical In fact in the last century ores of 4 percent grade were regarded as almost valueless Today such ores which would be regarded as relatively rich in copper are scarce the great majority of mines contain

The copper minerals and waste rock are separated at the mill using froth flotation The copper ore slurry from the grinding mills is mixed with milk of lime simply water and groundup limestone to give a basic pH pine oil yes it comes from trees a byproduct of paper mills to make bubbles an alcohol to strengthen the bubbles
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday use
Various process chemicals are used in the frothflotation of metallic ore of uranium copper zinc lead and iron The flotation chemicals are mainly Isooctyl Acid Phosphate Sodium Isopropyl Xanthate and Potassium Amyl Xanthate as conditioner and collector MIBC as frothers and sodium cyanide and copper sulfate as depressors
The process uses the difference in the wetting characteristics of minerals and gangue Minerals are generally wetted by oil and gangue is wetted by water So they prepare a mixture of the crushed ore with water oil and other substances And rotating paddles will then agitate such mixture and introduce air
In ore beneficiation flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer Sulfide and nonsulfide minerals as well as native metals are recovered by froth flotation
Feb 16 2018 · This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the wat
Oxidic ore can be concentrated using flotation or if it has a low acid demand it may be economic to acid heap leach the stockpile The recovery of these copper minerals by flotation or hydrometallurgy from ores typically containing 05TCu open pit mines and 12TCu underground mines
After carrying out a froth flotation separation the products are as shown in Table 1 Using this data calculate a Ratio of concentration b Metal Recovery c Metal Loss d Weight Recovery or Yield e Enrichment Ratio Table 1 Graderecovery performance of a hypothetical copper ore flotation process
According to the differences of physical and chemical properties of copper ore surface copper ore flotation production line is treated by flotation reagents the copper deposits are selectively stick to the bubbles for the purpose of separation Copper flotation process is divided into several stages such as crushing grinding and flotation etc
Froth Flotation Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material 1734
Copper sulfide ore Forth flotation process introduction Copper sulfide is a compound of copper and sulfur chemical formula CuS exist in the deep blue covellite forms in nature It is a medium conductivity conductor Hydrogen sulfide gas inlet into copper salt solution to form copper
2 Extraction of Metallic Copper Concentration of the ore by froth floatation process Copper pyrites contains only 23 of copper The rest of the ore contains iron or sulphide silica silicious materials sulphur arsenic etc as impurities Froth flotation by Xanthate and pine oil
Commonly Used Froth Flotation Reagents Collectors Collectors commonly used in the flotation process of gold and silver ores include xanthate black powder and butylammonium black powder Kerosene and transformer oil can be used as auxiliary collectors Oleic acid can also be used as a collector for goldcopper oxide ores
refractory oxides and sulphide copper minerals with an average grade of 137 total copper TCu with the goal of optimising the froth flotation process of Chingola Refractory Ores Cupriferous mica chalcocite bornite chalcopyrite malachite and pseudomalachite were the significant copper minerals in the ore
the flotation recovery of Ni Cu and Co from a nickelcopper sulphide ore The effect on flotation performance of various parameters such as pH collector dosage solids and depressant dosage at different levels was investigated Therefore the main objective of the study was to optimize the process parameters for the flotation of base metals
Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings To prepare ore for the flotation process runofmine ore which may contain from about 2 to 5 percent water by weight when mined is
Feb 17 2018 · This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the wat
After carrying out a froth flotation separation the products are as shown in Table 1 Using this data calculate a Ratio of concentration b Metal Recovery c Metal Loss d Weight Recovery or Yield e Enrichment Ratio Table 1 Graderecovery performance of a hypothetical copper ore flotation process
Copper ore divides into ore sulfide ore oxide and mixing ore according to its oxide rate The main process for copper ore is flotation for refractory mixed copper ore and refractory oxide ore normally use hydrometallurgy process It is a high technological enterprise that integrated research manufacture sales and service The company has multiple subsidiaries such as Mineral
With a broad range of froth flotation solutions and concise performance control Nalco Water can help you navigate fluctuations in ore and operation conditions minimizing potential losses Download the following brochure on the phosphate beneficiation process to learn more
Flotation Concentration at the mill using froth flotation The copper ore slurry from the at the tail end of this process is called FROTH FLOTATION RECENT TRENDS Flotation of Flotation of Sulphide Ores HZL Experience process Key Words Froth flotation Sulphide ores are major sources of base metals like Copper Lead
Jul 23 2014 · Froth flotation is a method for separating hydrophobic materials which will not mix with water from hydrophilic materials which readily mix with water Since its discovery froth flotation has been a major component for the processing of sulfiderich ores including copper
