Copied the below.

“Criticality also depends on time. Increasing global demand for renewable energy increases the value of critical minerals. Their use is extended from the manufacture of batteries to automobiles as well as manufacture of mineral refinery equipment and several others,” he added.

However, he said the minerals will no longer be critical when other minerals are discovered to replace them in the production of clean energy, noting that the concept of critical exists upon increasing demand.
