The material flow in the titanium industry is shown in Fig. 5.1.The ilmenite of <58% TiO 2 can be used for producing TiO 2 slag or TiO 2 pigment through the sulfate route The TiO 2 content will largely determine the relative values of titaniferous feedstocks, and the more TiO 2 there is in the material the greater its value. For comparison, the …
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 …
