Abstract

Indonesia is one of the countries in Asia that has very abundant resources. Tin is one of the most abundant mineral resources in Indonesia. Shaking Table is a tool whose main part consists of a table consisting of a slightly inclined deck that works due to the shock force and wash water which can increase the tin ore content and can increase the grade up to 72-74%. The tin content that is suitable for smelting is Sn with levels of 72-74%. Discharge and rifle height are variables contained in the shaking table that can affect the results of the tin washing process. Therefore, based on this, research was conducted on the analysis of the increase in tin content to meet the smelter industry standards. The results of the analysis showed that the sample feed consisted of cassiterite, xenotite, ilmenite, limonite, and quartz minerals. The results of the analysis carried out can be seen that the Sn content is 23.66%. A large water discharge will cause a large water thrust. However, if the water discharge is too large it will cause fine particles and heavy particles to be directly pushed into the concentrate container. The results of the research on the effect of rifle height on grade acquisition and recovery, namely the higher the rifle, the better the grade and recovery. However, if the rifle is too high it will cause the rotating current to be unable to stir and transport particles that are under the lowest layer of the inter-rifle area. The best grade and recovery were obtained at 35L/m water discharge and 0.4mm rifle height where in these conditions the levels and recovery were 73.72% and 88.01%, respectively.
