is protected by inert gas with certain pressure and discharged through the collecting system, and then is quenched by water, thereby magnetically roasted sample is obtained. Magnetic-tube concentrator... is separated with the magnetic-tube concentrator first, and then is subjected to chemical analysis and calculation to determine the content of mediumly and strongly magnetic minerals so......
capacity of each concentrator is 2 000 t/d. Since July 2004, the improvement achieved by the adoption of the Potential Control Flotation technology, is compared with the traditional technology. Fig.1 PCF process in concentrator of Mengzi lead-silver-zinc ore It can be seen from Table 3 that Pb, Zn flotation recovery and the grade of the concentrate are improved obviously by PCF technology......

,当ρ(Cu2+)0为25 mg/L时,除钴效果降低.因此,对于添加Cu2+和Cd2+用于锑盐净化除钴在85 ℃时的最佳条件为:ρ(Cu2+)0 15 mg/L和ρ(Cd2+)0 15 mg/L.超过此范围的ρ(Cu2+)0和ρ(Cd2+)0,除钴效果不明显或变差.这是因为,对于特定的锌粉和添加剂组合而言,锌粉表面的活化区域数量存在一个最大值[15].Nelson等[14]假定钴的置换沉积与能吸附在... electrolyte using the copper-antimony process[D].

两层产生烧结,否则就会产生分层,导致成形强度和精度变差,甚至无法成形.因此,对烧结深度的影响因素进行研究,通过合理选择工艺参数来控制烧结深度,具有十分重要的意义. 美国的Bourell等[5]以PMMA包覆的铜粉为成形材料,Nelson等[6]以聚碳酸脂包覆的陶瓷粉为成形材料,对上述材料的激光烧结成形工艺进行了实验,研究了激光能量参数与铺粉工艺参数对烧结深度的影响规律,但并未根据实验结果进行工艺...
