Vol. 4, No. 2. A New Application For Flotation Of Oxidized Copper Ore 69 RESULTS AND DISCUSSION The Flotation of Oxidized Copper Ore: This study was carried out under the conditions indicated in table 1. Flotation time was 3 minutes. In the first test with a run of mine ore sample, it was determined that the
In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur.
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.
In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant. It was established that recovery of copper and cobalt
Pneumatic flotation is already fully established in a number of places and the results in comparison with the other and older schemes fully justify the opinion of your correspondent that it constitutes the most distinct advance in flotation in recent years. The first pneumatic-flotation plant in this country was erected by me in February 1914 for the National Copper Company at Mullan, Idaho, a
Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. 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 ground-up limestone) to
The increasing complexity of ore deposits, declining ore grades and higher global demand for copper has resulted in increased ore processing by flotation plants around the world.
W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001. 1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral

A new method, staged flotation for effectively increasing the recovery of ultra-fine copper oxide ore with a new type of collector (ZH-1, C3-5 carbon chain xanthate) is proposed for the first time. The flotation process and mechanism were examined by flotation tests, entrainment rate analysis, laser particle size experiments and microscopic imagery as well as economic feasibility analysis.

Table II. Contribution of each mineralogical class to the copper losses in the final tails.
Poor floatability of oxidized copper ores has been widely known for a number of years (e.g. [6-10]. Generally, for the processing of oxide copper ores, two methods are used: 1) hydrometallurgical, and; 2) flotation, but for a long time the hydrometallurgical method (SX-EW) has dominated the technique of processing oxidized and mixed copper ores
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
The flotation machine with other names of flotation cell and flotation separator, made by the famous Chinese flotation machine manufacturer Fote Heavy Machinery, is mainly used not only to separate non-ferrous metals such as copper (usually using the copper ore flotation machine), zinc, lead, nickel and gold, but also to realize the rougher or

Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation-high-gradient magnetic separation-leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide as a vulcanizing agent and butyl xanthate as a collector.
the flotation recovery of Ni, Cu and Co from a nickel-copper 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

The flotation response of sulfide minerals in the Kansanshi mixed oxide-sulfide copper ore is superior compared to oxide minerals, for the given flotation conditions. The grade-recovery profiles and the flotation kinetics show improved results for copper sulfide minerals than oxide minerals.
Flotation of copper sulphides assisted by high intensity conditioning (HIC) crease in the grade and the increase of complex ores. Under actual conditions, a great deal of fine minerals is discarded as 1998), oxidized copper ores and copper and molybdenum sulphides (Rubio et al., 2003) and nickel ore (Chen et al., 1999).
