Comparing the extent of the dissolution of copper-cobalt ...

leaching of copper-cobalt oxide ores from the Central African Copperbelt by organic acids. In the present work, preliminary studies have been conducted to establish the feasibility of leaching using an organic acid. The leaching behaviour of a copper-cobalt oxide ore in an organic acid environment (tartaric acid) was compared with that in an inorganic

Bioleaching of cobalt from Cu/Co-rich sulfidic mine ...

01/11/2020· Bioleaching tests with a tailings flotation concentrate (Co 0.06%; Cu 0.57%) showed a recovery of 66% cobalt and 33% copper. In addition, mineralogical analysis showed that cobalt occurred on the surface of framboidal pyrite and was mainly leached by microbial attack. Attached cells were microscopically observed on the surface of solid particles of the bulk tailings and tailings flotation concentrate. The amount of sulfides (mainly pyrite) in the tailings …

Selective reductive leaching of cobalt and lithium from ...

In this article, the sulfuric acid leaching of industrially produced waste LIBs scraps with 23.6% cobalt (Co), 3.6% lithium (Li) and 6.2% copper (Cu) was investigated. The industrially produced LIBs scraps were shown to provide higher Li and Co leaching extractions compared to dissolution of corresponding amount of pure LiCoO2.

Leaching of Copper, Cobalt, and Nickel from Complex Ore ...

24/01/2020· The paper focuses on leaching of complex copper–cobalt–nickel ore from Mwinilunga district in Zambia, containing 0.6% Cu, 0.21% Co, 2.6% Fe, and 0.13% Ni. Mineralogical examination of the ore using scanning electron microscope (SEM) showed that copper, cobalt, and nickel exist in fine particles of heterogenite and limonite mineral phases. The effects of leaching …

01/11/2020· Bioleaching was more effective compared to chemical leaching. • Cobalt was efficiently bioleached from framboidal pyrite structures. • Biofilms on the tailings were characterized. Abstract. A microbial consortium of mesophilic and acidophilic bacteria and archaea was applied in shake flasks as well as in 2 L stirred tank reactors (STR) to bioleach cobalt, copper…

Flowsheet considerations for copper cobalt projects

Copper and cobalt production from oxide ore types in the African Copperbelt by agitation leaching followed by solvent extraction (SX) and electrowinning (EW) has been practiced for many years. The Tailings Leach Plant at Nchanga in Zambia was commissioned in 1974 and is still in operation today1. In recent years, more of these types of plants have been constructed …

13/11/2017· Cobalt is similar to copper in this respect. It's an essential mineral--B12 has it at its core. It's used in endoprosthetics, and loads of medical applications. Unless you're in the industrial abrasives business or live near a toxic waste dump, (or you're a Quebecois/Belgian alcoholic living in 1964), you're probably not getting cobalt poisoning.
