Over the years, people have come up with some ingenious ways to extract gold from ore, or the solid substance (like rocks or minerals) that contain valuable metals or minerals. People can crush the rocks, heat the rocks and even treat the rocks with chemicals. This lesson will explore the third option, focusing on how sodium cyanide is used to remove gold from ore in a process called gold cyanidation, or when cyanide i
