作者 李永聪 王金良 《化工矿物与加工》 CAS 北大核心 2002年第7期6-8,11,共4页
旬阳镜铁矿原矿全铁品位在 5 7%左右 ,单一强磁选获得TFe 6 5 %以上的铁精矿 ,回收率大于 85 % ;用摇床或螺旋溜槽进行重选也能选出品位合格的铁精矿 ,但回收率显著低于强磁选。浮选可产出高纯镜铁矿 ,再细磨可制得油漆填料云母氧化铁。
关键词 深加工试验 镜铁矿 强磁选 摇床 螺旋溜槽 浮选 油漆填料

[ Objective] The aim was to discuss the optimum fermentation technology of kiwi wine. [Method] Effects of pH, SO2 concentration, fer- mentation temperature, yeast inoculums amount on the quality of kiwi wine were investigated by single factor experiment and orthogonal experiment. P, esult] The optimum conditions were as follows: fermentation temperature (22 ℃ ), yeast inoculums (0.20 g/L), SO2 concentration (60 mg/L) and pH (3.5). The kiwi wine produced under these conditions was yellowish green, transparent, moderately acidic with strong fruit flavor and aro- ma. [ Conclusion]The study provided a theoretical foundation for the development and production of deeply processed products of kiwifruit. 展开更多

According to the characteristics of deep engineering surrounding rock main shaft of No.3 mining district in Jinchuan, electron microscope scanning and rock mechanics test were adopted to analyze the damage features of rock. The software of FLAG3D and Burgers body (Kelvin-Maxwell model) were used to research on rheological theory, and rheological model was modified. The results indicate that the damage of rock mass is very serious, and the rheological characteristics also outstanding; rheological behavior of deep surrounding rocks of the shaft can be taken as superposition of transient and stable rheology; and there exist the most dangerous zone on 100 m higher than 1 063 m level, so it is necessity that works of monitor and corresponding reinforcement should strengthen. 展开更多
