Magnesium oxide acts as an osmotic laxative, drawing water into the intestines to soften stool and relieve constipation. Studies confirm its efficacy in treating chronic constipation, with doses of 1.5 grams/day showing significant improvement in bowel movement frequency and stool quality.
Research highlights magnesium oxide's role in reducing migraine frequency and severity. A daily dose of 400–500 mg helps regulate neurotransmitters and improve cerebral blood flow, offering a safer alternative to conventional medications.
Magnesium oxide supports cardiovascular health by relaxing blood vessels and enhancing insulin sensitivity. Higher doses (600+ mg/day) are effective in lowering blood pressure and improving glycemic control in diabetic patients.
As a magnesium supplement, it aids bone mineral density (BMD) development, particularly in adolescents and postmenopausal women. Magnesium oxide ensures adequate mineral intake for skeletal strength.
Supplementation may alleviate stress by modulating the nervous system. Clinical trials show reduced anxiety levels in patients taking 500 mg/day of magnesium oxide.

MgO functions by participating in a replacement reaction within a cobalt-containing solution. This reaction leverages the higher reactivity of magnesium to reduce cobalt ions (Co²⁺) to their metallic form (Co), while MgO is transformed into magnesium hydroxide (Mg(OH)₂).
The core chemical equation illustrating this process is:
Co²⁺ + MgO + H₂O → Co + Mg(OH)₂
This reaction allows for the selective precipitation of cobalt metal, facilitating its separation from the remaining solution.
Cobalt Extraction from Ores: MgO is widely used to extract cobalt from cobalt-containing ores through hydrometallurgical leaching and subsequent precipitation.
Waste Lithium-ion Battery Recycling: As the demand for batteries grows, so does the need for recycling. MgO plays a crucial role in the selective recovery of cobalt from spent lithium-ion batteries, contributing to a circular economy.
The effectiveness of MgO in hydrometallurgy is greatly influenced by its properties. The following characteristics are highly desirable:
High Purity: High-purity MgO ensures minimal interference from impurities, leading to a cleaner and more efficient replacement reaction.
Uniform Particle Size: Consistent particle size promotes uniform reactivity, preventing localized over-reactions or incomplete metal precipitation.
High Reaction Activity: A high surface area and porous structure enhance the reactivity of MgO, leading to a faster and more complete cobalt recovery.

Safety First: Always prioritize safety when handling MgO. Wear appropriate personal protective equipment (PPE), including dust masks, gloves, and eye protection, to minimize the risk of inhalation or skin contact.
Dust Control: Minimize dust generation during handling and storage to prevent respiratory irritation. Work in well-ventilated areas.
Proper Storage: Store MgO in a dry, cool, and well-ventilated environment. Avoid exposure to moisture, as it can lead to caking or degradation.
Waste Disposal: Dispose of any waste materials containing MgO in accordance with local environmental regulations.
Specialized MgO for hydrometallurgical applications is available from numerous chemical companies both domestically and internationally. Key factors influencing the price of MgO include:
Purity: Higher purity grades typically command a premium price.
Particle Size Distribution: Uniform and optimized particle size ranges may also increase the cost.
Quantity Purchased: Bulk purchases often result in lower unit prices.
Research and comparison of different suppliers are recommended to secure the most cost-effective and suitable product for specific application needs.
Environmentally Responsible: The reaction products, such as magnesium hydroxide, can be recycled or utilized in other applications, contributing to a more sustainable process and minimizing environmental impact.
Safety Compliance: Ensure that the MgO used complies with relevant safety standards and regulations. Implement proper handling procedures to minimize risks associated with dust exposure and chemical reactions.
The field of hydrometallurgy is continuously evolving. Future research and development efforts are focused on:
Improving MgO Activity and Selectivity: Developing MgO with higher surface areas, optimized pore structures, and surface modifications to enhance reactivity and selectively target specific metal ions.
Expanding Applications: Exploring the use of MgO in the extraction and recovery of other valuable metals beyond cobalt, such as nickel, lithium, and rare earth elements.
Optimizing Process Parameters: Investigating and optimizing reaction conditions (temperature, pH, MgO dosage) to maximize metal recovery and minimize reagent consumption.
Innovative MgO Production Methods: Developing more sustainable and cost-effective methods for producing high-quality MgO from various sources, including seawater and industrial byproducts.
