The beneficiation of lithium minerals from hard rock

15/01/2019  In the early days of ore beneficiation, hand sorting was used to separate spodumene (Munson and Clarke, 1955) and gold ores (Barton and Peverett, 1980). However, the need to process a large tonnage of low grade ore, and the need for fine milling to improve mineral liberation led to the decline in the application of hand sorting in mineral processing ( Wills and Finch, 2016 ).
