Leaching ore is a process by which valuable metals are extracted from ore by dissolving them in a solvent such as water or acid. The process involves the use of chemical reagents that react with the valuable metal in the ore, causing it to dissolve and then be extracted from the solution. The leaching process can be used for a variety of ores, including gold, silver, copper, and uranium. It is often used in mining operations to extract the maximum amount of metal from the ore while minimizing environmental impacts.
