Lithium-boron extraction discovery

ASX-listed Global Geoscience has made an ‘ industry first’ lithium-boron extraction discovery at its Rhyolite Ridge project in Nevada.

Recent test work at the project found that lithium and boron could be readily extracted by simple heap leach processing with high recoveries of between 88 and 92 per cent.

Global Geoscience said heap leach processing provided significantly lower operating and capital costs compared to other forms of acid-leach processing as grinding, flotation, filtration and leach tanks are not required.

“This is a very significant breakthrough as we are not aware of any other lithium deposit where heap leach processing has been successfully demonstrated,” Global Geoscience managing director Bernard Rowe said.
