Optimization on the purification of cassiterite from low-grade cassiterite concentrate
IOP Conference Series: Earth and Environmental Science, 2020 Abstract Optimization on the purification of cassiterite from low-grade cassiterite concentrate has been successfully done. The concentrate used came from the mine site in the Delas area, Bangka Island with an element content of Sn was 31.60% wt and the impurity phases including zircon, ilmenite, quartz, hematite, and monazite.
