And wrt to natural gas usage…from du pleasis…
“Even though this is hard-rock mining, the process involves creating a material called Zinnwaldite - named after the area it comes from - is less energy-intensive than other lithium processes, such as spodumene, as it requires one less pyrometallurgical step than other processes," he said.

"Other ways of saving on emissions is the use of natural gases in kilns as opposed to the coal-firing used in a majority of lithium plants," he added. "While we may not be as environmentally friendly as brine producers in the Atacama - who often use solar energy for evaporation - we have the advantage of not also not having water supply or pollution issues."
