There are two economic sources of lithium; brines and hard rock ores. The majority of the global lithium production, greater than 60%, is produced from brines while lithium ores accounted for the remaining production (Ebensperger et al., 2005).Table 1 summarises the world's major lithium producers from ores and brines, and the total …
The application seeks to classify individual ore rocks based on the ratio of phosphorus to silicon wt.% content (actual P 2 O 5 /SiO 2 ratio) in real-time. Method development and testing was based on actual phosphate rock samples from Western Mining Corporation Resources Ltd., (WMC) Queensland, Australia.
Separation of refractory rock phosphate (P2O5 = 11.5%) from the Dalir area, Iran, containing quartz, calcite and other impurities, by calcination and flotation processes has been successfully used to upgrade the phosphate values.
