The best known hectorite deposit with 0.7% Li is found in Hector, California (Foshag, and Woodford, 1936). Jadarite (LiNaSiB 3 O 7 (OH)) is a lithium-boron containing mineral found in Serbia (Mohr et al., 2012). ... Studies conducted on the use of automated sorting methods in lithium ore beneficiation are scarce. However, this technique is ...
The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …
