Process to produce lithium carbonate from spodumene ore concentrates.

Summary of the technology

Process to produce lithium carbonate or other lithium chemicals from spodumene ore concentrates.
⇒ Replaces sulfuric acid with ferrous sulfate which is abundant, lower cost, and easier to transport and handle.
⇒ Process is easier to operate, since in traditional processes with sulfuric acid the acid pulp is very complex to handle.
⇒ Does not generate liquid effluents.
⇒ Generates two by-products with market value: lithium carbonate and red hematite

Laboratory prototypes

Proof of concept tests carried out in the University laboratories have focused on corroborating the chemical processes. The main product obtained from the process is lithium carbonate. Although there is still a need to carry out technical validation phases on a pilot scale, it is possible to estimate that for each ton of spodumene ore, the process allows the production of:

• Lithium carbonate: between 600 and 650 kg

• Red hematite and magnetite: between 400 and 350 kg

Desired business relationship

Joint ventures

Technology development

We are looking preferrably for a partnership with a company that is interested in collaborating with the University to continue maturing this development.

We are available for scheduling a virtual meeting with Dr. Igor Wilkomirsky Fuica, lead inventor of this technology, who will be able to tell in much greater detail what this technology is about and clarify any questions regarding the proposed process and its applications.
