摘要
针对商洛某低品位金红石精矿,探究磷酸二氢铵体系下焙烧条件对金红石精矿品位的影响,通过进行不同焙烧温度试验、磷酸二铵用量试验和焙烧时间试验,获得提升金红石精矿品质的适宜制备条件。试验结果表明,最佳反应条件为焙烧温度为1100℃,磷酸二氢铵用量为金红石质量的30%,焙烧时间为90 min。在此条件下浸出液中各种杂质的含量最多,得到的金红石品质最好,TiO_(2)含量为95.78%,提高了12.38个百分点。
Based on a low-grade rutile concentrate in Shangluo City,the effects of roasting conditions on the grade of rutile concentrate in a ammonium dihydrogen phosphate system are investigated.Experiments on different roasting temperatures,diammonium hydrogen phosphate dosage and roasting time are conducted,the suitable preparation conditions for improving the quality of rutile concentrate are obtained.The experimental results show that the optimal reaction conditions are a roasting temperature of 1100℃,a dosage of ammonium dihydrogen phosphate as per 30% of the mass of rutile,and a roasting time of 90 minutes.Under these conditions,the content of various impurities in the leaching solution is the highest,and the quality of the obtained rutile is the best.The TiO_(2) content is 95.78%,which is up by 12.38 percentage points.
