<![CDATA[The tailings produced from the previous processing are known to still contain valuable minerals such as cassiterite (SnO2), as well as associated minerals such as Fe, ilmenite, and zircon. Therefore, a beneficiation process is needed to optimize tin recovery and minimize the loss of valuable minerals. The beneficiation process includes sampling, sample reduction, grinding using a rod mill, and separation of valuable minerals using a shaking table and wet magnetic separator, as well as X-ray fluorescence (XRF) analysis. The XRF results of primary tin concentrate beneficiation using a shaking table increased the Sn content from 0.736-1.259% to 20-18.99% with a recovery of 1.779-7.456%. Magnetic separation of 40 kg of feed produced magnetic fractions of 5.7 kg and 18 kg, with Fe grades of 8.96–8.99% and Sn up to 4.90%. The grade increase was achieved, but Fe separation was still not optimal because some magnetic minerals were carried over to the non-magnetic fraction.]]>
