Magnetite Ore Benification Process
The beneficiation of lithium minerals from hard rock ores: …
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 reserves. The lithium …
