About Ores
- An ore may be referred to as a low grade ore which contains a small percentage of the mineral by mass or a high grade ore which contains a high percentage of the mineral by mass.
- The grade of an ore determines whether it is worth the cost and effort to extract the mineral.
- Low grade ores are usually extracted using phytomining or bioleaching which are cheap but take a long time.
