    摘要: 【課題】低品位の二酸化チタン鉱石から、二酸化チタンが高濃度に濃縮された高品位精鉱を低コストに製造する。
    【解決手段】粉状の二酸化チタン鉱石に逆浮遊選鉱(A)と浮遊選鉱(B)を順に施すに当たり、逆浮遊選鉱(A)では、陽イオン捕集剤と澱粉が添加されるとともに、pHが10以上に調整された水溶液中で精鉱を沈降分離し、浮遊選鉱(B)では、陰イオン捕集剤とフッ酸と気泡剤が添加されるとともに、pHが2〜3に調整された水溶液中で精鉱を浮遊分離する。 好ましくは、逆浮遊選鉱(A)−浮遊選鉱(B)の前工程として、粒度調整(F)を経て得られた粉状の二酸化チタン鉱石に比重選鉱(G)と磁力選鉱(H)を順に施し、逆浮遊選鉱(A)−浮遊選鉱(B)の後工程として、浮遊選鉱(B)において浮遊分離された精鉱に比重選鉱(C)と乾燥処理(D)と磁力選鉱(E)を順に施す。
