Based on the gold recovery and mineral processing techniques required, gold ores are commonly classifi ed into two major categories: free-milling and refractory ores. Typically, free-milling ores are defi ned as those where over 90% of gold can be recovered by conventional cyanide leaching. Refrac-tory ores give low gold recoveries or
These technologies are the basic technologies for mineral processing plants to extract gold from different types and grades of gold deposits. Of course, there are other Mineral processing technology. Reasonable gold ore beneficiation technology needs to be determined based on the type, form and other factors of the ore.
Chrome ore refers to natural deposits containing chromium in its original form. A hard, shiny, and corrosion-resistant metal, chrome ore is usually found in the earth's crust in the form of chromite.
