Design Of Magnetic Separator To Increase Tin Ore Content In Mining Laboratory Bangka Belitung University
Abstract
Magnetic separator testing uses two variables, namely the speed of the roller on the conveyor belt and
the feed speed. Due to the minimum number of variations that can be used in magnetic separator
testing, roller speed testing is used at 0.6 m / s and 0.7 m / s. the variation of figures at the feeding
speed of 0.21 kg / s and 0.35 kg / s so that 8 samples obtained from the processing of a magnetic
separator with 4 magnetic samples and 4 non-magnetic samples. The feed samples used were
prepared by drying and sifting into 3 size fractions to be used in the grain counting analysis process so
that the percentage of minerals contained in the sample were found: 15.82% Cassiterite, 63.95%
Ilmenite, 6.09% Monazite, 0.48% Pyrite / Marcasite, 1.61% Zircon, 1.44% Topaz, 0.65% Tourmaline
and 9.96% Quartz. The effect of roller speed on the increase tin ore content is still common, this is
because there are not many experiments carried out so that taking the trend of the influence of the
roller speed is too fast. The effect of feed speed, the greater the feed speed on the magnetic
separator, the smaller the tin ore content obtained.
