Learn more about Bischofite

Bischofite is a mineral with multiple industrial, environmental, and commercial applications.

Main uses of Bischofite

​​Thanks to its unique chemical properties, it has become an efficient solution for:

• Dust control and suppression on unpaved roads: used in surface irrigation or stabilization, Bischofite reduces water use on mining roads by more than 90%, making it a sustainable and economical alternative to traditional irrigation.
• Road ice prevention and control: its use in winter seasons prevents ice formation, ensuring safer driving on high mountain routes or in areas with low temperatures.
• Industrial and food applications: Bischofite is also used as a raw material in the chemical, agricultural, and food industries, especially for the production of Magnesium Chloride.

Key benefits of using Bischofite

• Water savings: significantly reduces consumption in dust control processes.
• Greater road durability: roads treated with Bischofite show less dust formation, calamine, and loss of material.
• Proven experience: in Chile, more than 6,000 kilometers have been stabilized with this technology.
• Environmental commitment: the use of Bischofite helps mitigate the environmental impact of mining operations and rural areas.
