The average copper content is 0.3 per cent, gold 0.8 g/t, silver 2.4 g/t and sulphur 12.7 per cent. The flotation tailings pond is located nearby Bor city centre and has great environmental impact.
1. Introduction. For copper–gold ores, it is a common practice to float copper sulphide minerals and the majority of gold to a concentrate. A review of large porphyry/skarn copper–gold deposits by Zheng and Manton (2010) highlighted that average gold recovery over four years of operation was 15% lower than that of copper. This was attributed, in part, to flotation operating …
The cyanidation of copper flotation tailings containing sulfides for gold recovery is an example of the formation of cyanide complexes with copper and silver during the leaching process [11,12]. Figure 4 shows the MLA Automated Minerology image of an ore sample from a copper mine in Mexico, containing chalcopyrite and bornite as copper sulfide ...
Copper–gold ores. Copper–gold ores are significant contributors to the overall world gold production. Flotation is the principal process for pre-concentration of the copper–gold minerals for subsequent smelting treatment. Gold recovery, although important, is not always considered when optimizing the copper circuit.
Key Words: Sulfurization, flotation, copper, gold, silver 1. INTRODUCTION Flotation has been utilized in the mineral processing industry to concentrate base metals and gold from sulphide ores since the beginning of the century. Many novel applications and fundamental studies have been produced to date to gain a more thorough
Mining & Processing methods. Upper zone: underground mining + flotation. The Čukaru Peki Copper-Gold Mine is a massive copper-gold mine in Serbia, with an Upper Zone and a Lower Zone. The Upper Zone has an ultra-high grade orebody and is scheduled to begin producing at the end of June 2021. On average, it is expected to produce 91,400 tonnes ...

The authors present the data on the substance analysis of gold–copper–arsenic flotation concentrate. Gold and copper recovery by autoclave leaching of the concentrate has been studied. It is found that maximum gold and copper recovery under optimum conditions reaches 96 and 92%, respectively. The profitability of the proposed process flowsheet is …
GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed …
In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process, flotation was adopted based on mineralogical analysis. Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite. The paper describes the effects of ratios …
Flotation tests were conducted on a sample of Boddington's copper–gold sulfide ores. Eucalyptus oil compositions were determined by gas chromatography–mass spectrometry. Gold association of flotation products was investigated by Mineral Liberation Analyzer.
Flowsheet for treatment of Copper Sulfide ores rich inminerals such as chalcopyrite with gold and silver as well as arsenopyrite. The above flowsheet is …
The CK Gold Project would be an open-pit mine, employing froth flotation to extract the valuable minerals. About two trucks per day of copper and gold rich concentrate would be shipped to existing, offsite facilities for final processing. While cyanide heap leaching is safely utilized in gold mining, the current CK Gold Project plan uses froth ...
Gold extraction involving flotation can be separated into four categories, free milling gold ores, copper gold ores, refractory gold ores and partially refractory gold ores (35). In this time ...
Advances in Coarse Particle Flotation - Copper and Gold. To achieve an efficient separation in the flotation process, valuable particles need to be selectively segregated from the gangue while utilising a minimum number of flotation stages. Today's existing flotation technologies are effective for fine particle size classes; however ...
17.7 Flotation of Gold-Containing Copper Ores. The floatability of gold from gold-containing copper gold ores depends on the nature and occurrence of gold in these ores, and its association with iron sulphides. Gold in the porphyry copper ore may appear as native gold, electrum, cuproaurid and sulphosalts associated with silver. During the ...
Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold ...

Flotation machine for gold orecopper ore processing. Introduction of Flotation Machine Flotation machine is widely used for flotation separation of metal ores such as gold ore copper ore lead ore zinc ore etc The flotation machine is driven by the motor Vbelt to rotate the impeller to generate centrifugal force to form a negative pressure
The copper flotation tailings were cyanided for 4 hours; 28.9 percent of the total gold and 35.8 percent, of the total silver were extracted, giving overall recoveries of 91.2 percent of the Gold and 97.0 percent of the silver. Cyanide consumption was 4.7 pounds per ton of original ore.

HAVING held for some months, in 1913, the position of metallurgist in charge of the flotation department at Mount Morgan, it occurred to the writer that a description of the research work that he carried out on that ore would be of interest to members of the Institute. The Mount Morgan ore is virtually a mixture of iron pyrites, copper pyrites, and gold in a quartzose gangue.
