In recent years, with the rapid development of China’s economy, especially the rapid development of the lithium battery industry, the demand for cobalt has also increased. There are mainly iron, copper and nickel ore in cobalt. Metal cobalt and cobalt oxide processing techniques are high, the smelting process is complicated, with high energy consumption, and serious pollution.
Cobalt Mine smelting recycling process
The coppe-cobalt ore recycling process mainly has the re-selection process and the flotation process, but the floating process is the most used process at present.
(1) Re -selection process
The mineral selection technology of copper cobalt ore is mainly used for cobalt vulcanizing minerals and gallium arsenide cobalt minerals, or use it with a flotation method to form a heavy-duty combined process. Copper cobalt ore has a certain magnetism. Although the test is used for cobalt recycling, it has not been promoted during the production process.
(2) Floating process
The floating process is still the main method for the recycling cobalt recycling of copper and cobalt ore. Specifically, it is to separate cobalt and other metal sulfides through floating technology. Whether a cobalt-cobalt method is used or cobalt suppressing depends on the differences between minerals and pulse minerals.
At this stage, the industrial foundation of African countries is thin, and all industrial auxiliary materials must be imported. In order to save costs, local enterprises still use sodium carbonate to extract sodium carbonate. Because the cobalt carbonate impurities are proposed, it contains a large amount of salt. If it is directly discharged to the environment, it will cause great defective to the environment. With the implementation of local environmental protection regulations, various African companies have begun to study other refined cobalt production processes. Among them the magnesium oxide is a direction of research.
Zehui Magnesium mainly produces magnesium compounds, including R&D centers and manufacturing plants. Recently, Zehui Magnesium R&D personnel added magnesium oxide to cobalt to obtain the following results:Magnesium Hydroxide produced by magnesium oxide can produce 0H-. The 0H-reaction generated by the CO2+ in the solution will be removed from the magnesium hydroxide electricity, and the CO (OH)2 is precipitated to continuously dissolve the magnesium oxide, and the CO (OH)2 continuously precipitates.
After the Zehui Magnesium-based experimental test, the results showed that magnesium oxide as a cobalt sink is half less than the amount of carbonate. Therefore, the cost of the auxiliary materials can be greatly reduced, which can also save the cost of logistics and warehousing. It is also an environmentally friendly cobalt product plan.
