MINING COBALT In “The Real Cost of Batteries”, you learned about the hazards of mining cobalt. This element is found in small amounts combined with other elements in minerals , naturally occurring solid substances that make up rocks. Countries around the world mine these minerals to collect cobalt. The table below shows the top cobalt-producing countries. Use the data in the table to complete the skills sheet.
