Researchers of the Ural Federal university made a breakthrough in solving one of the most pressing problems in the mining industry. They have developed a unique technology that not only extracts valuable components from ore, but also completely neutralizes dangerous arsenic, converting it into a safe form.
The new technique is applicable to a wide variety of raw materials – from natural ores to industrial waste. This makes the development a universal tool for increasing environmental safety. The key advantage is solving two problems simultaneously: maximizing the extraction of useful elements and radically reducing harm to the environment.
The innovative method is based on the use of special photocatalysts. These materials, such as those based on zinc oxide, are activated by light. During the reaction, they create active particles that destroy harmful impurities. Toxic trivalent arsenic is oxidized and converted into a stable, non-toxic form suitable for reliable long-term storage.
The technology does not require the addition of large amounts of chemicals, which simplifies the process and makes it more economical. The development is especially relevant for enterprises extracting gold, copper, lead and zinc. Arsenic is often found in the ores of these metals, creating serious risks for the environment and human health. A patent application for the invention has already been filed. The next step for scientists will be to adapt technology for processing new types of raw materials. The implementation of this development will pave the way for the mining industry to cleaner and safer production, combining economic efficiency with environmental responsibility.
