Flotation Of Cobalt Ore

Cobalt Flotation Recovery

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 (fig. …

19 - Flotation of Oxide Copper and Copper Cobalt Ores

Flotation of Oxide Copper and Copper Cobalt Ores 19.1 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,

Copper-Cobalt ores - Danafloat

Copper-Cobalt ores. The tails produced in the first differential flotation step is followed by a pyrite and pyrrhotite flotation stage using xanthate and MBT, leaving the cobalt minerals in the flotation cell tails. The cobalt minerals are then floated by using sulphuric acid to decrease the pulp pH to 4. Sodium sulphide is conditioned in the pulp.

Processing of Cobalt-Copper-Arsenic Complex Ore ...

Apr 06, 2007 · 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. This concentrate can be upgraded during flotation by removing iron, but with considerable cobalt loss.

Cobalt extraction - Wikipedia

The ore is comminuted and the cobalt rich oxides are separated by froth flotation. The cobalt-bearing concentrate is then mixed with lime and coal, and then melted in a reducing atmosphere. Iron and lighter impurities float to the surface as solid dross or are expelled from the melt as gas.

The ore is comminuted and the cobalt rich oxides are separated by froth flotation. The cobalt-bearing concentrate is then mixed with lime and coal, and then melted in a reducing atmosphere. Get Price

Cobalt processing | Britannica

The most important sulfide sources, the copper-cobalt ores of Congo (Kinshasa) and Zambia, are processed in the conventional manner to produce a copper-cobalt concentrate. This is then treated by flotation to separate a cobalt-rich concentrate for treatment in the cobalt circuit.

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.

Recovery of cobalt and copper through reprocessing of ...

In the Katanga province of the Democratic Republic of Congo (DRC), effluents from flotation of oxidised ores of copper and cobalt are stored in settling ponds in view separation of tailings and the mill wastewaters, which are sent in the rivers.

Nickel and Cobalt Ores: Flotation - ResearchGate

Flotation of cobalt sulfide ores can be best achieved at acidic pH (~. 4) with xanthate collectors and at pH of about 7.5 for oxide ores with nitrosonaphthol chelating reagents, while their mixture...

Improving the efficiency of oxide copper–cobalt ores ...

Flotation activators Sulphidising flotation of oxide copper–cobalt ores has found widespread application at Gécamines, a state owned mining company operating in southern Katanga, Democratic Republic of Congo. Copper mineralisation in this area is mainly composed of malachite, sometimes with the presence of pseudomalachite and chrysocolla.

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

differential flotation of copper cobalt ores | Solution ...

Oct 22, 2012 · flotation of oxide copper-cobalt ores, using sodium hydrosulphide as the sulphidising agent, has been practiced in Katanga, Democratic Republic of Congo. Electrochemistry Encyclopedia — Extracting metals from sulfide ores

SOME ASPECTS OF LABORATORY FLOTATION OF Co-Cu …

The RC 1 concentrate value for cobalt for this ore was invariably lower than the second and third etc concentrate values for repeat tests indicating an initial sluggishness of the cobalt minerals to flotation. This was in complete contrast to the behaviour of the copper
