1、假象赤铁矿(齐大山、司家营)与赤铁矿(海南石碌铁矿)在PH 2～12的广泛范围内,对烷基磺酸盐均有三个吸附峰,且位置十分相近。这将归因于赤铁矿与假象赤铁矿虽然成因不同,但晶格结构都基本一致。 2.海南赤铁矿与假象赤铁矿对烷基磺酸盐的吸附能力存有较大差异。值得注意的是在零电点附近,形成化学吸附的趋势不同,表现在浮游行为上,具有明显差异。经分析,这将归因于尽管两者晶格结构基本相同,但由于成因不同,两者在矿物晶体完整程度上有明显差别,另外两类矿粒的几何特性、解理面特性等表面性质的差异也是造成吸附及可浮性差别的重要因素。 3、使用烷基磺酸盐,假象赤铁矿在 PH 3～4及零电点处,均有较好的可浮性。但对海南赤铁矿则不同,在PH 3～4有较好的可浮性,而在零电点附近,用十二烷基磺酸盐表现为基本不浮,用十六烷基磺酸盐亦只有很弱的可浮性。
In the wide range of PH 2 ~ 12, there are three adsorption peaks for alkanesulfonates and the positions are very close similar. This is due to the fact that the hematite and the artifact hematite have different causal factors, but the lattice structures are basically the same. 2. Hainan hematite and artifact hematite alkyl sulfonate adsorption capacity there is a big difference. It is noteworthy that in the vicinity of the zero point, the formation of chemical adsorption trends are different, the performance of the floating behavior, with significant differences. The analysis shows that this is due to the fact that although the crystal lattice structures of the two are basically the same, due to the different causes, the two crystal minerals have significant differences in the degree of completeness. The other two types of mineral particles have different surface properties The difference is also an important factor in the difference between adsorption and floatability. 3, the use of alkyl sulfonate, illusion of hematite at PH 3 ~ 4 and zero point, have better floatability. However, it is different from Hainan hematite, and has good floatability at PH 3 ~ 4. In the vicinity of the zero point, the performance of hematite is basically not floating, with cetyl sulfonic acid Salt is also very weak floatability.
