Abstract

In an effort to look for more efficient energy resources, we now see a re-emergence of lithium as a viable energy alternative. Lithium has become a major contributor in the energy storage industry, providing longer lasting, smaller batteries that are more powerful and more reliable for consumers. This research project adds to the existing knowledge in the exploration of new ways to extract lithium. Parameters such as collector dosage and type, activator usage, feed size and pH level have been reported to have dramatically influenced the flotation recoveries of lithium. These parameters are investigated in this project.

The aim of this research project was to improve the recovery of hard rock lithium bearing minerals by flotation. This aim was achieved through a series of objectives that targeted collector type and dosage, feed size, activator usage and pH. The project was separated into a series of stages, leading to the eventual flotation of spodumene.

It was found that both feed size and pH level had significant impacts on the recovery of spodumene. When compared to baseline tests, an approximate increase in recovery by 30% was achieved. It was found that when both spodumene and lepidolite were floated at the same conditions, both minerals were able to attain a similar grade and recovery.
