Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal. Manganese ores are widespread, but most of the world's supply is from a small number of manganese mining districts. Most manganese ores are from extensive layers of manganese-rich sedimentary rocks that formed in ancient oceans under specialized conditions.
Thanks for the comment James. I think the chart mixes ore and metal based on how it's traded. As you point out the 20mt copper is metal produced, but no-one buys and sells copper ore.

Although the character of waste rock varies with the type of ore, many waste rocks contain sulfide minerals associated with metals, such as lead, zinc, copper, silver, or cadmium. An important sulfide mineral common in waste rock is pyrite, iron sulfide. When pyrite is exposed to air and water, it undergoes a chemical reaction called "oxidation."
