矿石

Live coals; tossd a live cigarette out the window; got a shock from a live wire; live ore is unmined ore; a live bomb; a live ball is one in play.

燃烧着的煤；把一根燃烧的香烟扔出窗外；被有电的电线打了一下；天然矿石就是没有开采的矿石；装有炸药的炸弹；活球就是正在打的球。

The center control building and transportation unit are control nerve centre. So,blasting should not cause yield accident.

由于大连港矿石码头中心控制楼和输送机组是矿石码头的控制中枢，所以在其附近的爆破不允许出现任何生产事故。

The experiments include the flotaion of the different types of the Yinshan ores with different kinds of the flotation reagents and different flowsheets. The authors consider that for the flotaion of the lead and zinc ores, the necessity of using cyanides as depressants depends chiefly on the amounts of pyrite present and its ...

作者认为，对于那些黄铁矿含量少或黄铁矿易被抑制的铅锌矿石，采用优先浮选而不用氰化物作抑制剂是可行的，但对于那些含量大且可浮性好的黄铁矿的矿石，如果完全不用氰化物则要从药方与流程等来考虑。

The sulphur in E'Kou Ironstone comes from sulphide (pyrite,pyrrhotite,chalcopyrite, binarite)and sporadically distributes in the ore or veined parallels/intercalates banded ferrosilicon formations.

峨口铁矿矿石中的硫来源于硫化物(黄铁矿、磁黄铁矿、黄铜矿、白铁矿)，呈星点状，散布于矿石中或呈脉体平行或穿切硅铁建造条带。

Study on the Effect of Slimes on Flotation of Zinc Oxide Mineral;2. The Determination for Eight Kinds of Elements in Wudalianchi Slime by Using Flame Atomic Absorption Spectrum;3. Test of reducing slime of oxidized zinc ore by using stirring mill has been carried out.

结果表明，搅拌磨能减少次生矿泥的产生，其原因主要是搅拌磨具有选择性破碎和自分级作用，粗粒级矿石受到的破碎作用力较强，而细粒级矿石受到较小的破碎作用力。

Various testings were conducted on the ore and the conclusions are as follows:Gold leaching rate is lower than 17% by all sliming cynidation;Gold leaching effect is poor by floatation and roasting cynidation;Bio preoxidizing cynidation and alkali soaking cynidation get the best results,the highest gold leading rate is up to 92 4%,and they are the effective meth...

通过各种选矿试验，该矿矿石用全泥氰化法金浸出率低于17％，浮选、焙烧氰化法浸出效果也不好，而用细菌预氧化、碱浸预氧化氰化法效果较好，金浸出率最高可达92.4％，是处理该类矿石较有效的选矿方法。

This reduction is made by subjecting the ore with coal to a hightemperature, either by the rapid and easy Catalan method, which has theadvantage of transforming the ore into iron in a single operation, or bythe blast furnace, which first smelts the ore, then changes it into iron,by carrying away the three to four per cent.

这个还原过程是用炭把矿石烧到温度很高的时候进行的，可以用迅速而简便的土法（它的优点是只通过一道工序，就能把铁矿石炼成铁），也可以用鼓风炉——第一步使铁矿石熔化，然后排除和矿石化合在一起的百分之三至四的炭，使它变成铁。

The leading products include whole set mine-selecting equipment and sandstone equipment such as ball mill, crusher, grinder, magnetic separator, flotation machine, classifier, drier, sand-maker, oscillating screen, sand washer, conveyor, block making machine, aac equipment, etc. Mine-selecting equipment is applicable to select non-ferrous metal ore such as iron, copper, gold, silver, lead, tungsten, molybdenum, manganese and non-metal ores such as fluorite and quartz.

主导产品包括一整套矿选设备和砂岩设备，如球磨机，破碎机，研磨机，磁选机，浮选机，分级机，烘干机，沙决策者，振荡画面中，沙洗浆机，输送机，砌块成型机，设备的AAC等矿选设备，是适用于选择非铁金属矿石，如铁，铜，金，银，铅，钨，钼，锰和非金属矿石，如萤石和石英。

A combined berth possess of functions of 70,OOODWT international trade bulk coal ship loading and 100,OOODWT international trade bulk ore ship unloading, which length is within the need of ship berthing tie length by measures of making loader and unloader in one set and a reversing belt conveyor system. In a relative low investment, the imminence problem, faced by LIANYUNGANG port, of how to deal with the reverse flow direction bulk international trade coal and ore handled in high handling efficiency, huge transport ship and relatively low individual freight volume may be solved.

本文运用&装卸船设备合一&的设想，在连云港港10万吨级散货泊位系统改造工程中，将7万吨级的外贸煤炭装船泊位和10万吨级的矿石卸船泊位合二为一，并通过采用装卸船二用机和可双向运行的皮带机输送系统，使泊位的长度保持在10万吨级船型带缆所需的要求之内，宽度也不增加，以较低的投资解决了港口迫切需要解决的外贸煤炭和矿石二个运输船型较大、流向相反的货种的高效率装卸船问题。

Gold ore contains only trace amount of valuable elements,and yielding much more tailings after pro- cessing and metallurgy than other metals ore.

黄金矿石有价元素含量很少，经选冶后产生比其它金属矿石更多的尾矿。
