Titano-magnetite sand deposit were discovered alongs the sounth coast of Java, between Progo and Bogowonto Rivers and to the sounth of Kutoarjo & Purworejo cities. The amounts of deposits were estimated to be 28,5 million tons of concentrate (59% Fe) and 86 million tons of concentrate (59% Fe) from the two above areas respectively. Samples of titano-magnetite sand were taken from the deposit near desa Bugel, Kecamatan Kulon Progo. By using magnetic separation process, the sand was able to be concentrated to 59% Fr. However, this iron content is still low as compared to the requirement of need materials for steel making, i.e 65-66%. This might be due to the high content of titanium oxide, i.e. 8-10% and other physical characteristic. Hence, in order to get higher Fe content, there should be futher study to improve the magnetic separation process or to investigate alternative processes.
