| 1 | Explaining surface interactions for common associated gangues of rare earth minerals in response to the oxalic acid显示文摘In the flotation of rare earth minerals(REMs), oxalic acid is reportedly acting both as a depressant and p H modifier. Although results of testing have established the significance of oxalic acid in the flotation process, its specific role in either the recovery or selectivity of REMs over their common gangue minerals is not well understood. Pulp p H reduction trials with alternative acids have not shown the same effect on the REMs recovery or the depression of gangue phases. This work studies the effect of oxalic acid on the surface of common REMs gangue minerals(quartz and carbonates(dolomite and calcite)) in a series of conditioning tests. Gangue surface analyses by time of flight secondary ion mass spectroscopy(TOFSIMS) indicate that oxalic acid inhibits the transfer of secondary ions generated during the conditioning process from one mineral to another. In this regard, the oxalate anion acts to fix ions in solution through chelation, limiting their participation in surface adsorption. | Saeed Chehreh Chelgani Brian Hart | 2018 | International Journal of Mining Science and Technology2018，28，2： | 6 |
| 2 | 球磨介质及尺寸对铜锌矿矿浆化学性质及矿物表面化学性质的影响显示文摘采用飞行时间二次离子质谱仪和改良球磨机研究了磨矿环境对铜锌矿矿浆的化学性质和闪锌矿的表面化学性质的影响。通过采用改良后的球磨机实现磨矿过程中溶液p H、矿浆电位、电导率、溶解氧含量及离子浓度等矿浆化学性质的实时监测。随着磨矿时间的延长,矿浆p H值缓慢升高,矿浆电位和溶解氧含量迅速下降。结果表明:球形磨矿介质的直径越小,矿浆中溶解氧消耗越快,磨矿后矿浆静电位越低,矿浆的离子浓度也越低。飞行时间二次离子质谱仪对磨矿后闪锌矿的表面化学分析表明,磨矿后铁氧化物和氢氧化物会附着于闪锌矿表面,球磨介质的材料与尺寸大小对矿物表面存在的二次离子有较大影响。分别与不锈钢球或者2.54 cm的大球相比,铸铁球或1.27 cm的小球可为矿浆提供更多的铁离子,促进磨矿环境下的电化学反应,从而在闪锌矿表面累积更多的铁氧化物或氢氧化物,降低铜离子的吸附。因此,矿浆化学性质和闪锌矿的表面化学性质受磨矿介质的材料与介质的尺寸控制。 | 陈哲 夏柳荫 Brian HART 池汝安 余军霞 | 2017 | 中国有色金属学报2017，27，8： | 4 |
