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 orMore Details
Is there a way for flotation of copper oxide? Is it possible to recovery up to 75 percent achieved? I have sample that about 45% of copper oxide and about 40% recovery was achieved with the SIPX and Sodium Mercaptobenzothiazole Dithiophoishate collector. I need to know how to increase copper …More Details
Oxide copper ore flotation with 800 g/ton sodium oleate at pH 9 yielded 14.4% Cu with 83.3% recovery in a rougher circuit. To enhance the flotation performance, in terms of %Cu, optimum dosages of sodium silicate, quebracho, and pine oil were examined. At the optimum dosages, the grade increased to 20.1% Cu with 76.4% recoveryMore Details
Flotation of Copper oxide ore. The floatability of copper oxide ores is generally worse than that of copper sulfide ores, and is greatly influenced by the existing form of copper in minerals and gangue composition. For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica malachite) is …More Details
Jan 01, 2019 · The flotation of copper oxide can be mainly divided into direct flotation and sulphidizing flotation. The collectors for direct flotation are fatty acids, fatty amine, petroleum sulfonate and hydroximic acids [10,11]More Details
Oct 27, 2020 · Flotation is one of the commonly used mineral processing techniques for copper oxide ores. According to the different properties of copper oxide ores, there are sulphidizing flotation, fatty acid flotation, amine flotation, emulsion flotation and chelating agent-neutral oil flotation method. Flotation method of copper oxide ore 1More Details
According to the nature of the copper oxide ore and the nature of the collector used, the copper oxide ore flotation method is divided into direct flotation and stage vulcanization-flotation. Copper exists mainly in the form of sulfide ore and oxidized ore in nature, the most important of which is sulfide ore, which is formed by the slow oxidative deterioration of sulfide oreMore Details
Sep 27, 2019 · In the copper oxide flotation, direct flotation method usually can not achieve better results. Sulfuration flotation method is the main flotation method for treating copper oxide ore and mixed ore at home and abroad. For malachite, azurite, and red copper. Mine-based copper oxide ore can get better indicatorsMore Details
Jul 01, 2019 · Of the total copper content, 38% can be found in copper oxide minerals and in the oxide flotation stage the maximum increase in copper recovery is 20%. Assuming that oxides are only recovered during the oxide flotation stage, Cu-oxide minerals recovery can be …More Details
Education Resources. Copper Mining and Extraction: Oxide Ores. Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of …More Details
Nov 09, 2020 · These copper oxide ores are usually leached using sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate solutionMore Details
The copper flotation circuits upgrade copper content by a factor of 80-160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed (remaining gold is recovered both as a gravity product within the primary grinding circuit and also via leaching of a gold-containing pyrite concentrate)More Details
Sep 10, 2011 · Flotation of difficult-to-float copper porphyry ores indicates that the primary reasons for the problems are mineralogical diversity, metallurgical factors, and process limitations. A detailed analysis of these factors indicates that, most often, difficulties in the flotation of copper porphyry ores arise due to mineralogy and metallurgy interrelated factorsMore Details
