Testing produced lithium carbonate with a purity of approximately 99.1% from the initial bench tests. This test program was conducted under the supervision of Dr.
The technical grade of Li2CO3 product and recovery of Li2O from flotation concentrates are considered excellent.
The success of this program has encouraged
Work to date continues to demonstrate a 'greener' process: lower temperatures, lower chemical needs, shorter processing times versus incumbent technologies point toward the environmental and CO2 impacts of high grade lithium salts production to be substantially reduced. Reagents and water consumption can be minimized by recycling the process streams such as filtrates, washes, evaporated water and crude products to the Li2CO3 precipitation, impurity removal, and water leaching stages.
When additional test work to convert spodumene concentrate into lithium carbonate is completed, a life cycle assessment for this innovative process is planned, and engineering data will be available to support decision making. A test program to optimize the calcination and roasting portions of the flowsheet to make them even more environmentally friendly is being designed by the company's President and CEO
'Test work to date has demonstrated that it is possible to modify traditional processes and shortcut lithium carbonate production using innovative out of the box thinking.
The detailed bench test work to develop a flowsheet was conceived and supervised by Dr.
