Flotation of mixed oxide sulphide copper-cobalt minerals,Jul 01, 2019· Bulk flotation experiments with Zambian copper-cobalt sulphide ore showed superior flotation performance, with improved kinetics, when using Sodium Ethyl Xanthate (SEX) as a collector instead of a blend of alkyl dithiophosphate and thionocarbamate collectors, with copper sulphides floating more rapidly than cobalt sulphides (Mainza et al., 1999).
Mineralogical Prediction of Flotation Performance for a,As part of a study investigating the influence of mineralogical variability in a sediment hosted copper–cobalt deposit in the Democratic Republic of Congo on flotation performance, the flotation of nine sulphide ore samples was investigated through laboratory batch kinetics tests and quantitative mineral analyses. Using a range of ore samples from the same deposit the influence of mineralogy
Copper-Cobalt ores Danafloat,Bulk flotation sequence: Under the bulk flotation process, a bulk Cu-Co flotation concentrate is produced at natural pH with xanthate, dithiophosphate and/or MBT, particularly if the copper mineralization is chalcocite. Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt

Improving the efficiency of oxide copper–cobalt ores,Abstract Sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide used as sulphidising agent is common practice in Katanga, Democratic Republic of Congo. From laboratory investigations, sodium hydrosulphide proved to enhance flotation selectivity of copper and cobalt towards the gangue minerals, while ammonium sulphide emerged as a strong non-selective sulphidiser.
A New Application For Flotation Of Oxidized Copper Ore,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.
Application of Knelson Concentrator for Beneficiation of,The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity concentration
cobalt processing Uses, Supply, & Facts Britannica,Cobalt processing, preparation of the metal for use in various products. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal close-packed crystal structure. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face-centred cubic. The metal has 12
Cobalt and Nickel Recovery From Missouri Lead Belt,100 million pounds of cobalt and 150 million pounds of nicke 1 (1., .§.)3 is of enhanced importance because the cobalt and nickel content can be upgraded as a result of mill-ing operations. Although the ore contains an average of less than 0.04 pct Co plus Ni, 50 to 55 pct of this content is concentrated

Introduction of cobalt flotation : The flotation machine impeller rotates by triangle belt of the motor, with produces centrifugal function and causes negative pressure.On one hand it draws in enough air mixed with ore magma on the other hand it agitates to mix ore magma with chemical medicines.
Improving the efficiency of oxide copper–cobalt ores,Abstract Sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide used as sulphidising agent is common practice in Katanga, Democratic Republic of Congo. From laboratory investigations, sodium hydrosulphide proved to enhance flotation selectivity of copper and cobalt towards the gangue minerals, while ammonium sulphide emerged as a strong non-selective sulphidiser.
(PDF) Mineralogical Prediction of Flotation Performance,The latter, including a sulphide flotation stage at neutral pH and a carbonate flotation stage at acid-pH allowed to increase the overall copper and cobalt recoveries.
