| 2 | 从沃萨奇烟煤中选择性浮选化石树脂显示文摘前言许多烟煤中贮存着少量的天然树脂。在美国西部煤田,特别是犹他州沃萨奇高原煤田发现了高树脂原煤,有些煤层的树脂含量平均为5%以上。怀俄明州南部中心地区的汗纳煤田和新墨西哥的圣胡安也发现了这种树脂质煤,含量为1~3%。沃萨奇高原煤田自1929年就开始采用重力方法或浮选方法回收树脂,生产树脂的规模极小,该煤田有4座选煤厂,其中仅1座选煤厂回收这种有价值的资源,其产量甚低。通常树脂精矿的生产是采用溶剂萃取方法精炼并经沉淀析出。标准纯树脂1克分子约重730,熔点约170℃,含碘数约145。 | J.D.Miller 王道温 | 1989 | 煤炭加工与综合利用1989，，5： | 0 |
| 3 | Dispersion of ultrafine alumina in modifier solution ——the role of polar interfacial interaction显示文摘Dispersion of ultrafine alumina suspension is examined by using particle size analyzer. The zeta potential and contact angle measurements were used to discuss the electrokinetic behavior and surface wettability of alumina in modifier solution, and to calculate the electrostatic interaction forces and interfacial interaction forces between alumina particles. The aggregation of ultrafine alumina occurs near its PZC. Addition of modifier increases the zeta potential of alumina and its surface hydrophilicity, resulting in increase of electrostatic and hydration repulsion. It makes the suspension of ultrafine alumina completely dispersed. The average particle size of the suspension is decreased from 1.73 μm in absence of modifier to 0.8 μm in the presence of tripolyphosphate. According to polar interfacial interaction approach, the hydration forces responsible for the stability of alumina suspension in the presence of modifier have also been obtained. The extended DLVO theory is successful to describe the dispersion behavior of ultrafine alumina in modifier solution. | HU Yue hua 1,QIU Guan zhou 1,J.D.Miller 2 (1.Department of Mineral Engineering, Central South University, Changsha 410083, China 2.Department of Metallurgical Engineering, University of Utah, 412 WBB, Salt Lake City, UT 84112, USA) | 2001 | Journal of Central South University of Technology2001，8，1： | 0 |
| 4 | 用烷基磷酸酯从碱性氰化物溶液中选择性溶剂化萃取金显示文摘研究结果表明,烷基磷酸醋可从碱性氰化物溶液中溶剂化萃取金。看来磷酸三丁酯(TBP)和丁基膦酸二丁酯似乎都是金的有效萃取剂,且其饱和容量都高于30g/L。在一定条件下,从碱性氰化物溶液中萃取金的选择性系数比其它的含氰阴离子高1000倍。根据萃取化学原理(其中还包括M^+…Au(CN)_(2^-)离子对的溶剂化作用),讨论了诸如离子强度、温度和萃取剂结构等参数对萃取选择性的影响。 | J.D.Miller 王德荫 | 1989 | 湿法冶金1989，8，1： | 0 |
