A purity of 99.5% lithium carbonate is required for battery grade lithium carbonate.
As the purity level rises, more potential product applications become available and possible pricing rises.
Conventional methods of extraction utilised
A 0.8 kilogram sample of lithium carbonate was produced by Prospect Resources at the company’s laboratory in Zimbabwe
In conjunction with CSIRO Australia’s Bentley laboratory in Perth the material was purified to 99.8% lithium carbonate.
The test work process was based on conventional methods of extraction of lithium from petalite concentrate.
Prospect Resources is establishing a lithium carbonate pilot plant in Zimbabwe using the same production techniques used to generate these results.
Prefeasibility study to be completed in the first quarter of 2018
The company is preparing a pre-feasibility study for a lithium carbonate and hydroxide plant fed by the entire lithium mineral concentrate production of the Arcadia mine.
It was only at the start of December that Prospect Resources delivered a significant increase in the ore reserve at Arcadia, and it now stands at 26.9 million tonnes at 1.31% lithium.
Prospect Resources aims to be the first ASX listed lithium company to produce its own battery grade lithium carbonate from its hard rock resources.
