The saturated solution can be directly recycled in distillation and turned into renewed solvent which has the same dissolving performance as the untapped one.After disparting from aluminum foil, the mixture of LiCoO_2 and acetylene black was lixiviated to extract cobalt ion. The leaching efficiency of cobalt was shown to be as high as 90% in the lixiviation experiments.

对钴锂膜上与铝箔脱离后的LiCoO_2、乙炔黑混合粉末，通过浸出钴的实验研究，确定了盐酸体系为合适的浸出体系，在盐酸浓度为6.67mol/L，反应温度80℃，反应时间50分钟的最优化浸出条件下，钴金属的浸出率可达90%以上。

The lixiviation ability of heavy metal in the ancient smelting residue has declined. Only a very small part of Zn lixiviated at a few locations, the amount of Pb leaching is below the detection limit, and only a small amount of Cr and Cd leaching occurs.

古冶炼废渣浸出能力减弱，废渣中Zn仅部分点位有极少量浸出，Pb的浸出量甚至在检出限以下，Cr和Cd也仅有少量浸出。

This subject is on the basis of a detail investigation of present utilization and recovery of pyrite cinder, and taking pyrite cinder from the Jinshandian vitriol factory of Wuhan Steel and Mining Industry Corporation as raw material. FeSO_4 is produced by adopting baking of pyrite cinder and vitriol lixiviation, and introducing the new high price ion during the course of making Poly ferric Sulphate to make Iron-modified flocculants.

本课题在对目前硫铁矿烧渣回收及利用现状进行深入综合考察的基础上，利用武钢矿业公司金山店铁矿硫酸厂的硫铁矿烧渣为原料，采用还原焙烧，酸浸工艺制取硫酸亚铁，在制取聚合硫酸铁的基础上引入新的高价离子，制取复合聚铁絮凝剂。

The results show that when the depth gradually reduces, pH values gradually increase, but conductivities and (superscript – subscript 3) content gradually reduce. There are also obvious differences between the groundwater in loess, alluvial deposit and acidity rock in the south of Chang'an, which relates to the depth, the characters of loess, the lixiviation and the evaporation. The element content of groundwater is high in the loess tableland, so it's fitter for drinking than the groundwater in the Cuihua mountains, which is of acidity and low element content.

结果表明，长安南部黄土塬随着层位的降低，pH值有逐渐增大趋势，电导率和HCO(上标–下标 3)含量有逐渐减少的趋势；黄土地下水、冲积层地下水和酸性岩石地下水的化学成分存在明显差异，这与其理深、地层性质、溶滤与蒸发作用不同有关；长安南部少陵源黄土地下水元素含量较高，比呈酸性、元素含量低的翠华山泉水更适于饮用。

Results: D-glucan is the main component of lentinan produced, its purity is 74.4％ and the recovery 79.6％. At the room temperature, the pH around lixiviation medium and 0.15～0.18 MPa, micropore filtration is better than centrifugal as pretreatment.

结果：在此实验范围内，用微滤作预处理较离心法效果好，超滤温度为25℃，pH值接近浸提介质的pH，超滤压力为0.15～0.18MPa，制得香菇多糖的纯度为74.4％，回收率79.6％，是以D-葡聚糖为主的混和多糖。
