铁矿

This study was to find a new cationic collector with better selectivity and collectability than alkyl amine to realize the selective flotation of silica from the iron ore.

本文对新型CS系列阳离子药剂及常规阳离子药剂对石英、磁铁矿和镜铁矿三种矿物浮选行为的影响规律进行了系统的研究。

Because Zhaokou mine of Jinling iron mine of Shandong make use of strata pressure controlling theory to do reasonable dividing for declinate ore body room and pillar ,the calculated recovery ratio η is up to 73 6% and maintaining the stability of mining field at the same time.

山东金岭铁矿召口分矿运用地压控制理论，对倾斜矿体房柱进行合理划分，计算回采率η达73。

In the batch incubation with addition of Asadsorbing ferrihydrite, the presence of arsenicresistant denitrificator caused an increase in concentrations of Fe and Mn, a decrease in concentrations of NO-3 and As, and a high ratio of As to the total As.

在吸附有砷的水铁矿体系中，反硝化菌所产生的反硝化作用可导致溶液中NO-3含量的降低、Fe含量的升高、As含量降低，且As所占比例增加。

This indicates that both the reductive dissolution of ferrihydrite and the reductive desorption of As occurred in the batches incubated with arsenicresistant denitrificator and Asadsorbing ferrihydrite.

这说明，体系中水铁矿的还原性溶解和As的还原性解吸已经发生。

Based on the research, founded on existing production conditions, production capability and technical natures of KISC, especially its own development requirements, linked with the development trend of the iron and steel industry, fully considering the continuity of equipment upgrade and technical optimization of KISC, guided under principles of validity and benefit, the writer analyses and argues that in current conditions. KISC shall not adopt the hot metal pretreatment of desiliconization, dephosphorization and desulphurization, but the end-point converter process to improve the dephosphorization effect. But according to the development plan of KISC, with its scale development, upgradeof equipment and technical conditions and implementation of a plan to use high-phosphorus ironstone, its more suitable to adopt the converter-shaped pretreatment of desiliconization, dephosphorization and desulphurization.

在此研究基础上，立足昆钢当前生产条件、生产能力和工艺特点，特别是昆钢自身发展需要，结合钢铁工业发展趋势，充分考虑昆钢现行装备改造和工艺优化的延续性，以有效性和经济性原则为指导，分析讨论了在昆钢当前条件下，不适宜采用铁水&三脱&预处理工艺，而宜考虑采用转炉复吹技术以达到改善转炉吹炼过程脱磷效果的目的；而根据昆钢的发展规划，随着昆钢的规模化发展，生产装备及工艺条件的更新改善及利用高磷铁矿计划的实施，则适宜采用转炉型&三脱&预处理技术。

So some researches on the microbial pretreatment and floatation desulphurization in coal are carried out.

为此，我们借助燃煤微生物预处理与浮选相结合的工艺来进行脱除煤中黄铁矿硫的研究。

The giant Bayan Obo REE-Nb-Fe deposit is the world's largest REE deposit,which is hosted mainly by Middle Proterozoic Na-rich rocks,dolomitic rock and K-rich slate.

白云鄂博稀土-铌-铁矿是世界最大的稀土多金属矿床之一，主要产于中元古界富钠岩石、白云岩和富钾板岩中。

Discussion of productive technology of continuity in developing emulsive explosive

在论述KYS-1乳化剂研制原理的基础上，介绍了其研制过程及在大孤山铁矿的工业试验情况，分析了利用KYS-1乳化剂生产的乳化炸药的爆破效果。

Polymeric ferric sulfate was prepared by pyrite cinder in this paper.

本文进行了用硫铁矿烧渣制备聚合硫酸铁的实验研究。

We have tested several terrestrial samples, such as Mo, Ti, Ni, ilmenite, titanite, rutile, pyrite, forsterite and melilite. We have also attempted to analyze our first meteorite sample.

我们已经测试了许多地球标本，包含了钼、钛、镍与钛铁矿、楔石、金红石、黄铁矿、镁橄榄石和方柱石，同时也尝试了我们第一个陨石的标本。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
