When copper is being mined, both Native copper and copper ore are usually found. The highest grade of copper ore is pale silvery gray. Miners used to be always in danger in copper mines. Today, we have reduced a fair amount of these hazards. Miners wear hats made of iron or very hard plastic. This is to protect them from falling rocks.
