Magnesium hydroxide: a versatile tool in gold and silver smelting

In the field of precious metal processing, gold and silver smelting is a key step, and magnesium hydroxide plays a vital role in this process. This article takes an in-depth look at how magnesium hydroxide can optimize the gold and silver smelting process and improve the quality of the final product.

1. The smelting effect of magnesium hydroxide: Due to its unique chemical properties, magnesium hydroxide can effectively lower the melting point of gold and silver and accelerate the melting process. During smelting, magnesium hydroxide interacts with the metal melt to promote the melting of gold and silver, while neutralizing the acidic components in the melt and improving the smelting state of the metal.

2. Dual effects of impurity removal and protection: Magnesium hydroxide can not only react with impurities during gold and silver smelting to improve metal purity, but also act as a protective agent to prevent gold and silver from oxidizing. This dual role reduces metal loss, increases the recovery rate of gold and silver, and ensures the economic benefits of precious metals.

3. Application skills and process control: In actual operation, the amount, timing and furnace temperature of magnesium hydroxide added have a significant impact on the smelting effect. Reasonable addition amount and precise timing can maximize the effect of magnesium hydroxide, while appropriate furnace temperature ensures the activity of magnesium hydroxide and avoids adverse effects on gold and silver.

4. The latest progress in magnesium hydroxide preparation technology: With the development of technology, the preparation methods of magnesium hydroxide are also constantly improving. For example, by optimizing the design of an electric furnace and controlling the temperature distribution within the furnace, high-quality single crystal magnesium oxide can be produced. In addition, high-purity magnesium hydroxide prepared from salt lake resources can be used to produce high-purity magnesium oxide crystal materials through specific technological processes.

The application of magnesium hydroxide in gold and silver smelting not only improves smelting efficiency, but also improves the purity and recovery rate of gold and silver through impurity removal and protection. With the continuous innovation of preparation technology, magnesium hydroxide will be more widely used, bringing higher economic and environmental benefits to the precious metal processing industry.
