Commercial Lithium Production and Mining of Lithium

 · In contrast to salar brine sources, extraction of lithium from spodumene, lepidolite, petalite, amblygonite, and eucryptite requires a wide range of processes. Because of the amount of energy consumption and materials required, lithium production from mining is a much more costly process than brine extraction, even though these minerals have a ...

The Missing Ethics of Mining : Ethics & International Affairs

A sane mining ethic would establish limits on prolonging extraction once the grade reaches an unsustainable level in an area, rather than continuing to expand as if the resource were infinite. Setting these limits would require interfering, as Dr. Keenleyside suggested more than sixty years ago, "with the free play of a market that is ...
