SGS has experience with lithium mineralogy, metallurgy and processing in support of the recovery of high-grade lithium products from hard rock lithium-bearing minerals such as spodumene.

SGS offers a multi-disciplinary team that can be involved from the initial stages of the characterisation of the lithium deposit right to the production of a market sample of a high-grade lithium product.

SGS provides the comprehensive range of testwork capabilities required to extract lithium. These capabilities include:

  • Comprehensive high definition mineralogy 
  • Comprehensive grindability tests
  • Mineral separation (gravity, heavy liquid and heavy media)
  • Flotation
  • Pyrometallury (concentrate roasting and acid roasting)
  • Hydrometallurgy
  • Pilot plant testing
  • Environmental testing

Lithium is a strategic metal that presents processing challenges due to its low specific gravity, inert nature and poor flotation response. SGS has the expertise, technologies and experience to help you overcome these and generate an effective processing solution for your project.
