Other lithium-bearing pegmatite silicates include lepidolite and petalite. Once the material has been decrepitated, or converted to beta-phase spodumene (-form), an additional calcination step is required. NOT FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES. This phenomenon made the complete conversion of the sample complicated. Here again, materials of construction must be highly resistant to the corrosive nature of the material being processed. The higher-value products from brines outweigh the higher cost and result in a forecast average 2019 margin of US$5,386/t LCE, almost twice that of their hard-rock counterparts.
