Magnesium sulfate heptahydrate (molecular formula MgSO4.7H20), also known as bitter sulfur, bitter salt, Epsom salt, Epsom salt, is a white or colorless needle-shaped or oblique columnar crystal, odorless, cool and slightly bitter, molecular weight: 246.47, specific gravity 1.68, easily soluble in water, slightly soluble in ethanol or glycerol, soluble in its crystal water at 67.5 ℃. Decomposed by heat, 70/80 ℃ is to lose four molecules of crystal water. About 200 ℃ loses all crystal water to become anhydrous. It is easy to weather into powder in the air (dry) and gradually loses crystal water when heated to become anhydrous magnesium sulfate. This product does not contain any toxic substances. Because magnesium sulfate heptahydrate is not easy to decompose, it is easier to weigh than anhydrous magnesium sulfate, which is convenient for quantitative control in industry.

Leaching is a process in which ore is brought into contact with a chemical solution to dissolve valuable metals from the ore. Magnesium sulfate heptahydrate as a leaching agent has shown many advantages in the mining field:
1. Enhance metal leaching rate: Magnesium sulfate heptahydrate can significantly increase the leaching rate of certain metals. The magnesium ions and sulfate ions in the solution can form soluble complexes with the metal ions in the ore, making the metal easier to dissolve. Research shows that when magnesium sulfate heptahydrate is leaching copper, zinc and other metals, the leaching rate can be increased by 10-15%.
2. Improve the selectivity of the leaching process: Magnesium sulfate heptahydrate has good selectivity in the leaching process, and can effectively distinguish between valuable metals and priceless metals, reducing the leaching of impurities. This not only improves the purity of the metal, but also reduces the difficulty and cost of subsequent purification steps. For example, when leaching copper-containing ores, magnesium sulfate heptahydrate can effectively avoid the dissolution of priceless metals such as iron, thereby increasing the recovery rate of copper.
3. Increase the leaching speed: Magnesium sulfate heptahydrate can speed up the leaching reaction speed and shorten the leaching time. Its high solubility and good ionic activity promote the full contact between mineral particles and leaching agent and increase the reaction rate. According to experimental data, using magnesium sulfate heptahydrate as a leaching agent can shorten the leaching time by 20-30%.
4. Maintain the stability of the leachate: Magnesium sulfate heptahydrate can form a stable chemical environment in the solution and maintain the stability of the leachate. This is particularly important for long-term leaching processes, which can prevent the metal in the leach solution from re-precipitating and improve the metal recovery rate. Experiments show that magnesium sulfate heptahydrate can extend the stability time of the leach solution by 25-35%.
5. Environmental protection advantages: Magnesium sulfate heptahydrate has good environmental compatibility. Compared with other strong acid leaching agents, such as sulfuric acid and hydrochloric acid, magnesium sulfate heptahydrate has less impact on the environment. It is completely soluble in water, does not produce harmful gases, and its residues cause less pollution to soil and water bodies. This gives it significant advantages in environmental protection and is especially suitable for mining areas with high environmental protection requirements.
6. Economic benefits: Magnesium sulfate heptahydrate is relatively cheap, widely available and easy to purchase. Its high efficiency and low cost in leaching significantly reduce the overall leaching cost. Market research shows that using magnesium sulfate heptahydrate as a leaching agent can reduce the total cost of leaching by about 15-20%. In addition, due to its increased metal recovery rate and leaching speed, it indirectly increases economic benefits.
