Result showed that DFOB could promote the release of REEs from goethite but increase the adsorption onto humic acid and montmorilonite. The increase in adsorption amount is attributed to the release of iron from these two minerals.

结果表明，DFOB能促进稀土元素从针铁矿表面的释放，但却提高了腐殖酸和蒙脱土对稀土的吸附，这种吸附量的增加是由于DFOB促进矿物中铁的释放而增加了矿物中吸附点位所造成的。

The results show that the maximum growth quantity of Nocardia can be achieved after culturing 120 h and obvious selective adsorption of Nocardia on the surface of pyrite and sphalerite can be detected. The maximum adsorption rate on the surface of pyrite is 96.99%, whereas it is less than 20% in the case of sphalerite. Adsorption equilibrium can be attained within 20 min on the surfaces of the two minerals. pH value is the key factor influencing upon selective adsorption, and the difference of adsorption quantity on the surfaces of two minerals is apparent when pH is between 4 and 10. Slurry concentration over 6 g/L is favorable to selective adsorption. Nocardia cell concentration, stirring speed and temperature have no obviously effect on selective adsorption.

结果表明：培养120 h后诺卡氏菌达到最大生长量；诺卡氏菌在黄铁矿和闪锌矿表面发生明显的选择性吸附，在黄铁矿表面的最大吸附率可达到96.99％，而在闪锌矿表面的吸附率大都在20％以下；诺卡氏菌在两种矿物表面于20 min内即可达到吸附平衡； pH值是影响诺卡氏菌在两种矿物表面发生选择性吸附的关键因素， pH在4～10之间时，选择性吸附现象明显；矿浆浓度超过6 g/L时有利于发生选择性吸附；细胞悬浊液浓度、搅拌速度和温度对吸附效果影响不大，均可产生选择性吸附。

For Ochrept,the total ofexchangeable and nonexchangeable can play as a standard for long time harvesting.Thecontribution of mineral potassium was larger in Ochrept than in Ustochrepts.

通过对不同形态钾素对植株吸钾的有效性分析，发现矿物钾对植株吸钾是有贡献的，但其贡献率因土壤不同而有很大的差异，褐土矿物钾的贡献率比潮土的要大。

In acid pulp, the depressing abilities of reagents on diaspore are in the order of hydroxamic acid starch＞dialdehyde starch＞carboxymethyl starch＞cationic starch＞primary starch. In addition, hydroxamic acid starch and carboxymethyl starch can activate kaolinite without influence on the recoveries of pyrophyllite and illite, so the two reagents have great potential and prospect to be the depressant of diaspore and the activator of kaolinite in bauxite reverse flotation.(3) By oximation of the copolymer of acrylamide and methyl acrylate, hydroxamic acid polyacrylamide is synthesized.
