在我省文山州富宁县普听河等河流的河沙中含有钛铁矿砂,初步地质勘探查明,每立方米河砂含钛铁矿37公斤,该矿易采易选,含硫、磷、钙、镁等杂质低,在国内各矿中属于质量较好者,富宁选厂的实践与我们的实验表明,经手淘洗将 TiO_2含量富集到40%左右,再用摇床重选而后经磁选可把 TiO_2含量提高到51.3%,S、P 量分别为0.012%与0.018%。显然,从该矿可以选出符合生产部门 Ilmenite sand is contained in rivers and streams of Pu’ning River in Funing County, Wenshan Prefecture. According to the preliminary geological exploration, 37 kilos of ilmenite ore per cubic meter of river sand is found, The phosphorus, calcium, magnesium and other impurities are low, which belong to the better quality in all the mines in China. The practice of Fu-Ning selection plant and our experiments show that the content of TiO_2 is enriched to 40% After selection, the content of TiO 2 can be increased to 51.3% by magnetic separation, and the contents of S and P are 0.012% and 0.018% respectively. Obviously, from the mine can be selected in line with the production sector
