Abstract :In Japan we have various kinds of iron sands buried. Although many attempts have been made to utilise these iron sands as the source of both iron and TiO_2-pigment they didn't succeeded until 1949. In 1949 they have succeeded industrially to produce pig iron of low P-content and the slag containing 40 to 60% TiO_2, from the iron sand of 30 to 35% TiO_2-content. This investigation has been done to see whether these kinds of slags are suitable as the raw material of TiO_2-pigment production, principally from the standpoint of digestion yield and the quality of the pigment odtained therefrom. The results can be summarised as follows: 1. Digestion yield is somewhat lower than that of the ilmenite. 2. Slags with relatively high content of Fe_2O_3 give low digestion yields. 3. As to the quality of the TiO_2-pigment obtained, it can be said that among the basic constituents, Al, Mg and Ca has no appreciable bad influence on the quality of the pigment. 4. But, as already reported by some other
