铁的

A new preparation method of high efficient flocculant polysilicate ferrite with iron mud and water glass was studied,and the reasonable production process and operation conditions were determined.

研究了以铁泥、硅酸钠为原料，制备高效絮凝剂聚硅酸铁的方法，确定了合理的生产工艺和操作条件。

A coarser grade of iron will lower the yield of ferrocene.

粗粒的铁将降低二茂铁的产量。

So, it is better to control the iron reduction degree to be 60%. Correspondingly, the leaching rate of nickel and iron is about 85% and not over 30%, respectively.

因此铁还原度控制在60%为宜，相应的镍浸出率约为85%，而铁的浸出率不超过30%。

The experimental result shows that under the condition of lixiviating time being 2.5~3 hours, lixiviating temperature being 110℃, sulphuric acid thickness being 6 mol/L, hydrochloric acid thickness being 3 mol/L, liquid-to-solid quality ratio being 4∶1, the extraction rate of iron will reach 95.7%~96.3% in mass fraction.

丁文武 淮海工学院，连云港 222005通过正交实验研究了用盐酸、硫酸、褐铁矿和硅酸钠制备聚硅氯化硫酸铁絮凝剂的工艺条件。实验结果表明，浸取时间为2.5～3 h，浸取温度为110℃，硫酸浓度为6 mol/L，盐酸浓度为3 mol/L，质量液固比为4∶1，铁的浸出率可达95.7%～96.3%。

Leaching sulphate concentration was increased when inoculation concentrations superinduced, difference between 25% and 50% inoculation was not obviously after several days of bioleaching.

该菌在培养过程中pH先上升后下降最后稳定在2.0左右，60h培养后溶液中的亚铁离子浓度降至检测范围以下，同时生成含有三价铁的褐色沉淀。

Various Iron-removing technologies by producing copper sulfate with copper-smelting smoke dust have been studied and compared.

炼铜烟灰含有大量有价金属，由于其铁含量较高，在回收过程中，除铁的好坏直接影响产品的质量。

His legs of iron, his feet part of iron and part of clay.

2：33 腿是铁的，脚是半铁半泥的。

And the legs of iron, the feet part of iron and part of clay.

胫是铁的，脚一部份是铁，一部份是泥的。

Its legs of iron, its feet partly of iron and partly of clay.

2：33 腿是铁的，脚是半铁半泥的。

Its legs of iron, its feet partly of iron and partly of baked clay.

02：33 腿是铁的，脚是半铁半泥的。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
