选矿

In some cases, when the ore dressing machinery factory the size of large ore blocks is also a great degree, in order to reduce the paragraphs broken ratio, or the product in order to get a finer granularity, can also be broken processes, Sec.

在个别情况下，当选矿机械厂的规模很大，原矿块度也很大，为了减少各段破碎比，或者为了得到更细的产品粒度，也可用四段破碎流程。

Silicon dioxide content of the multitudinous samples in the ore dressing test was assayed.

But I suppose you have to go to out-of-the-way places to tap likely spots.

但是我想你们也经常到很偏僻的地方去选矿。

Through research of mineral processing and purification to one pegmatite in Xinjiang province ,our laboratory had successfully discovered one feasible method on economy and technology.

我实验室通过对新疆某伟晶岩矿石的选矿提纯研究，成功发现了一个经济技术都可行的方法，精矿电气石回收率达到80%以上，品位90%。

Henan Seiko Machinery Co., Ltd., formerly known as China First Tractor Plant equipment, the early nineties the focus of development and production of waste powder Raymond Mill Series, Series beneficiation equipment, crushing equipment, stone cutting line and its ancillary equipment.

河南精工机械设备有限公司，前身为中国一拖配套设备厂，九十年代初重点开发生产废雷蒙磨粉机系列、系列选矿设备、破碎设备、石材切割系列及其附属设备。

Produce the BF gas mud 100, OOOt every year. The raw mineral of puddling is the magnetite containing vanadium and titanium. The grade of iron is only 53%. The grade of sinter mineral is only 47-48%. So the percentage composition of iron is relatively low, only 29.70%. The grade of zinc is relatively high, reach 9.92%. And the percentage composition of carbon is relatively high, reach 16. 80%. In the next place, the BF gas mud is the production through sinter in high temperature.

攀钢炼铁的原矿物为钒钛磁铁矿，铁品位仅为53％，烧结矿品位为47％～48％，所以攀钢高炉瓦斯泥的铁品位也相对较低，仅为29.70％，并且含锌量高，达到了9.92％，含碳则高达16.80％；其次高炉瓦斯泥是高炉冶炼过程中的产物，SiO_2、Al_2O_3和铁部分熔融在一起，选矿难度增加。

Sludge of Pan Steel were firstly disposed by mineral seperation and then the mill tailings of sludge were reduced by pyrometallurgy process to reclaim zinc, and iron in the slag tails were reclaimed by magnetic seperation.
