Cyanide leaching is a process used in mining to extract precious metals, primarily gold and silver, from ore. In this method, a cyanide solution is applied to crushed ore, allowing the metals to dissolve into the liquid. The resulting solution is then collected for further processing to recover the metals. This technique is favored for its efficiency and effectiveness, especially for low-grade ores. However, it raises environmental concerns due to the toxicity of cyanide, which can pose risks to wildlife and water sources if not managed properly. Safe practices and regulations are essential to minimize these risks.
