Neutralize the treatment agent and adjust the pH value

The use of Brucite ore and its calcined product as a neutralizing treatment agent is the most widely used field of medium and low grade brucite. Due to the buffering properties of Magnesium Hydroxide or Magnesium Oxide, the pH value can be kept at around 9 during the operation, even if the pH value is not exceeded, and it is easy to grasp, it can be widely used in the petrochemical industry for acidic wastewater and waste. The treatment of the liquid regulates the acid-base balance of the soil (adjusts the pH) and adsorbs heavy metals.

The treatment of acidic liquids discharged from coal mines and metal mines is a serious environmental problem. Using magnesium hydroxide as a treatment agent, the acidity and dissolved heavy metal ions in AMD can be removed, the pH value is not more than 9.5, and the sedimentation object is dense, which is far superior to slaked lime and caustic soda, and the latter two are used as the treatment agent PH value. Both exceed 12, far exceeding the values specified by the US Environmental Protection Agency.
