Structural Characterization and Adsorption Capability of …
In the process of gold leaching, the adsorption/complexation between carbonaceous matters and gold–cyanide complexes is called the "preg-robbing" phenomenon. Especially, studies have shown that the carbonaceous matters can trigger the "preg-robbing" phenomenon when the content in a gold ore exceeds 0.2% . In addition, …
