Hebei Meixi Biotechnology Co., Ltd. said that magnesium oxide has a wide range of application scenarios in the nickel and cobalt industry, which not only improves the recovery efficiency and product purity of cobalt and nickel, but also reduces production costs and environmental pollution risks. With the continuous progress of technology and the promotion of environmental protection policies, the application prospect of magnesium oxide in the nickel and cobalt industry will be broader.
As a cobalt immersant:
In the extraction process of nickel and cobalt, magnesium oxide acts as an efficient cobalt president, which can quickly react with cobalt ions in solution to form a stable cobalt hydroxide precipitate. This reaction increases the efficiency of cobalt recovery and ensures the purity of the final product. For example, activated magnesium oxide can produce cobalt hydroxide with a cobalt content of about 33% and a cobalt recovery rate of more than 94% when processing low-cobalt liquids.
Improve product quality:
The high purity of magnesium oxide allows it to minimize the introduction of impurities during the reaction, thus guaranteeing the purity and stability of the final product. This high-purity cobalt-nickel product has a wide range of application prospects in stainless steel, battery, petrochemical and other industries.
Reduced production costs:
Compared with the traditional sodium carbonate cobalt immersion process, the use of magnesium oxide as a cobalt immersion agent can significantly reduce the production cost. On the one hand, magnesium oxide has a higher reaction efficiency, which can reduce energy consumption and material waste; On the other hand, the magnesium sulfate waste liquid formed is easier to dispose of, further reducing the cost of wastewater treatment.
Environmental Advantages:
The environmental advantages of magnesium oxide in the extraction of nickel and cobalt cannot be ignored. The magnesium sulfate waste liquid formed is easy to recycle and reuse, reducing the risk of environmental pollution. In the current environment of increasingly strict environmental protection policies, this environmental advantage is particularly important.
Special Process Applications:
Magnesium oxide also plays a key role in some special processes, such as the hydrometallurgy of laterite nickel ore. The magnesium oxide slurry was obtained by wet grinding of low-activity magnesium oxide, and then reacted with nickel sulfate solution to obtain nickel hydroxide and cobalt hydroxide precipitates. This process not only improves the recovery rate of nickel and cobalt, but also reduces production costs.
Market Demand & Forecast:
With the maturity of magnesium oxide cobalt technology and the promotion of environmental protection policies, the application of magnesium oxide in the nickel and cobalt industry will continue to grow. Especially in large cobalt consuming countries such as China, the ratio of magnesium oxide export volume to use will become an important data to predict its application in the market.
