CONTINUOUS FLOTATION TESTING TO RECOVER COBALT FROM MISSOURI lEAD ORES By W L Cornell,1 A M Wethington,2 D C Holtgrefe,3 and F H Sharp1 ABSTRACT The Missouri lead ores are the only domestic sources of cobalt presently being mined and processed for other materials They represent the best short-term solution for
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 .
Flotation of Oxide Copper and Copper Cobalt Ores 191 INTRODUCTION Flotation practice of oxide copper minerals dates back to almost 60 years ago, and has been applied in Central Africa (Congo) by Union Miniere (Belgium) The process involves two basic flotation methods: (a) fatty acid flotation of oxide copper minerals from siliceous ore.
These rather sudden ore feed grade changes can result in reduced flotation plant efficiency and hence losses in income The prime objective of the project, to selectively recover and concentrate cobalt oxi-dized minerals by froth flotation, was not fully achieved on the ores tested
A sequential flotation process for the recovery of high-grade concentrates of copper, lead and cobalt-nickel from sulfide ores is provided A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration, and the conditioned pulp subjected to sequential flotation, with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation step for copper
Laboratory batch flotation tests were conducted to determine the effect of two types of gasoil-rinkalore mixtures on the flotation response of a copper cobalt oxide ore sample
Froth flotation is considered to be the most widely used method for ore beneficiation 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

The major cobalt source in the ore is the mineral siegenite Separation and concentration of siegenite by froth flotation is complicated by the mineralogy of the ore The siegenite is often present as an intimate replacement intergrowth with chalcopyrite (fig 1), sphalerite, galena ,
Extraction of cobalt from complex ore flotation concentrates obtained from the Blackbird Mine Idaho USA is reviewed After flotation of a primary copper concentrate, a bulk concentrate is recovered containing major amounts of cobalt, arsenic, and iron, with minor amounts of copper and nickel

From the above, it can be concluded that sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide as sulphidising agent exhibits a good selectivity of copper and cobalt flotation towards the gangue minerals On the other hand, the use of ammonium sulphide induces higher metals recoveries with very low selectivity
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilicThis is used in mineral processing, paper recycling and waste-water treatment industri Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century
Sep 29, 2017· Copper-cobalt ores are primarily found in Zambia and the DRC, where the cobalt is recovered from copper flotation concentrates, using a roast-leach-electrowin (RLE) process The ore is roasted (for sulfides), followed by a sulfuric acid atmospheric leach, and direct electrowinning of copper
The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered – eg the Kolwezi Tailings Project
