DESCRIPTION
Electrolytic manganese production is a process that involves the electrolysis of a solution containing manganese sulfate and sulfuric acid. The process is used to produce high-purity manganese metal and dioxide, which are used in a variety of applications, such as steel production, battery production, and chemical synthesis.
The electrolytic manganese production process can be summarized as follows:
Preparation of the electrolyte: Manganese sulfate and sulfuric acid are dissolved in water to create an electrolyte solution with a specific concentration.
Preparation of the anodes and cathodes: The anodes are made of lead or lead alloy, while the cathodes are made of stainless steel. The anodes are coated with manganese dioxide to improve their electrochemical performance.
Electrolysis: The anodes and cathodes are immersed in the electrolyte solution and connected to a direct current (DC) power supply. The current causes the manganese ions to migrate from the electrolyte solution to the cathodes, where they are reduced to metallic manganese. Meanwhile, the anodes release oxygen, which reacts with the manganese ions in the electrolyte solution to form manganese dioxide.
Manganese recovery: The manganese metal deposited on the cathodes is harvested and further processed to remove impurities and create high-purity manganese metal. The manganese dioxide produced at the anodes is harvested and sold as a product.
Regeneration of the electrolyte: The spent electrolyte solution is collected and treated to remove impurities, such as iron and aluminum, before being recycled back into the process.
