For instance, if an ore has a copper grade of 1%, it means that in every 100 kilograms of the ore, there is 1 kilogram of copper. Grams per Tonne (g/t): Precious metals like gold and silver are typically measured in grams per tonne. If a gold ore has a grade of 5g/t, it means there are 5 grams of gold in every tonne of that ore. Types of Grade:
At the end of this step, copper ore concentrate levels are typically between 24 and 40 percent. After concentration, the next phase in creating market-ready copper is refining.
