The test result shows:(1) Concentration after grind finely, multi product configuration, regrind and reconcentratipn of sulphide iron ore, and firstly recovering tin and removing sulfide ore as possible as are available metholds to improve the grade and recovery of tin concentrate, simplify technology flowsheet and reduce production cost;(2) Intensifying the recovery of single stage concentration table is the key to concentration to concentration after grind firely and improving index. The recovery of fine tin is sure to further improve index;(3) Regrind and reconcentration of ferro-sulphur ore may recovery some tin.

试验研究结果表明：(1)细磨入选，多产品结构，硫化铁矿物再磨再选，能拿早拿、能丢早丢，预先脱出硫化矿物是提高锡精矿品位和回收率，简化工艺流程，降低生产成本的有效途径；(2)强化一段摇床的回收是细磨入选，提高指标的关键，细粒锡石的回收是进一步提高指标的根本保证；(3)硫铁矿物再磨再选也可回收部分锡金属。

Test results indicate that adding 10 percent ultra-fine lime stone powder blending material can obviously improve the early compression strength of concrete,and that the bending strength of concrete will be improved along with increase of addition amount of lime stone powder when the addition amount is less than 30 percent.

结果表明，掺入10%的超磨细石灰石粉掺合料可显著提高混凝土的早期抗压强度，当石灰石粉掺量小于30%时，抗折强度随其掺量的增加而提高。

Design and optimize HSC of fine sand and pebbles with Dn-'s optimum design,explore the internal law between water-bond ratio,the amount of super fine slag powder,sand rate and properties of HSC,and build the corresponding mathematical model.

用Dn 最优设计的方法试验设计并优化配制了细砂、卵石高强混凝土，探索了细砂卵石混凝土中水胶比、磨细矿渣粉掺量、砂率与高强混凝土性能之间的内在规律，并建立了相应的数学模型。

Some trial and research results of slag concrete abroad are introduced.

0引，磨细的粒状高炉矿渣是混凝土的一种理想的胶结成分。

By original material comparing experiment, it confirms the various original materials of the high performance concrete and fine slag.

通过前期的原材料比选试验，确定了高性能混凝土的各项原材料以及磨细矿渣种类。

This article mainly studied under the marine environment to degrade insize the slag concrete the influence.

摘要翻译求助用翻译软件的请走开！~本文主要研究了海洋环境下对磨细矿渣混凝土的影响。

By this method,a sample of ground ore can be ascertained in the short time of a day whether it is refractory,whether it is necessary to be treated in the presence of acidic medium or alkaline medium and what oxidant should be employed.

在拿到磨细矿石后一天内就可判断出这种矿石是易处理矿，还是难处理矿，是需要在酸性介质中处理还是需要在碱性介质中处理，以及选择多大氧化能力的氧化剂。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
