Barite-Fluorspar-Zinc Ore Grinding. The ore for treatment is of such a nature that conventional grinding to —65 mesh using a ball mill classifier circuit results in excessive overgrinding of the barite. To avoid this condition a rod mill is used instead of a ball mill for reducing the feed for flotation.
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 …
