Levels of exposure were estimated for the following operations: milling, mixing, machine line, sawing, and grinding. Asbestos concentrations ranged from – f/mL in 1956, to – f/mL in 1969, and to – f/mL in 1975. In all three time periods, the highest concentrations were observed in the milling and grinding operations.
Mar 06, 2019 About 99% of manganese ore was exported to China in 2017–2018. The import of manganese ore is much higher than export in terms of quantity and value.
