Gold recovery refers to the process of extracting gold from various sources, including ores, electronic waste, and jewelry. This process can involve several methods, such as cyanide leaching, gravity separation, and smelting. Each method has its own advantages and is chosen based on the type of material being processed and the desired purity of the gold. In recent years, gold recovery has gained attention due to the increasing demand for recycled materials and the environmental impact of mining. Techniques like bioleaching and hydrometallurgy are being explored to make gold recovery more sustainable and efficient, reducing the need for traditional mining practices.
