Using optical microscope, manual artificial heavy concentrate, electron microprobe and scanning electron microscopy, we tested major gold- bearing minerals in Zhaishang deposit. Pyrite and scheelite are the most important gold-bearing minerals. Quartz, limonite, and chalcocite are the secondary gold-bearing minerals. Calcite, siderite, barite and other minerals do not contain any gold.

通过光学显微镜、人工重砂、电子探针、扫描电镜等显微测试手段对寨上矿区主要载金矿物进行分析测试得出：黄铁矿、白钨矿是最主要的载金矿物之一，石英、褐铁矿、辉铜矿是次要的载金矿物，方解石、菱铁矿、重晶石等不含金。

At the same time, the SEM study shows that gibbsite occurs on the sample surface. At 200 ℃, as dawsonite sandstone is being dissolved authigenic siderite forms. At 300℃, chlorite deposit on parts of the sample surface. The weak solution of dawsonite sandstone at 100℃ and the formation of siderite at 200℃ illuminate that CO2 being in carbonates in the strata can not be released when CO2 phase is adding to the system.

同时，各温度下样品表面均有一水软铝石放射状集合体沉淀。200℃时，随着片钠铝石的溶解有自生菱铁矿生成，300℃时样品局部有绿泥石沉淀。100℃下片钠铝石的微弱溶解及200℃下菱铁矿的形成表明，在地层条件下以碳酸盐矿物形式捕获的CO2，不会由于CO2的二次注入而重新释放。

The proven iron ore reserves of 140 million tons, ore varieties have hematite, limonite, red limonite and siderite, the type of deposit for the Shanxi-style iron.

铁矿的探明储量为1.4亿吨，矿石品种有赤铁矿、褐铁矿、赤褐铁矿和菱铁矿，矿床的类型为山西式铁矿。

The study on magnetizing reduction thermodymatics of high intensity magnetic separation concentrates of Daye Mine proved: because of there are high siderite in this type iron ore, CO and CO2 emitting out after siderite decomposing influenced on magnetic reaction heavily.

大冶铁矿尾矿难选红铁矿磁化焙烧热力学分析表明，因为该类矿石菱铁矿含量高，分解后产生CO和CO2对磁化焙烧反应影响较大，在CO含量大于1%的情况下，磁化焙烧即能完成。

It provided us with technology and theory basement on industry furnace research and design.The study on magnetizing reduction thermodymatics of high intensity magnetic separation concentrates of Daye Mine proved:because of there are high siderite in this type iron ore,CO and CO_2 emitting out after siderite decomposing influenced on magnetic reaction heavily.

大冶铁矿尾矿难选红铁矿磁化焙烧热力学分析表明，因为该类矿石菱铁矿含量高，分解后产生CO和CO_2对磁化焙烧反应影响较大，在CO含量大于1%的情况下，磁化焙烧即能完成。

The result of studying is that the minerals of Fe in A layer clay-stone of kaolinite are hematite, goethite and siderite, but the most is hematite and goethite.

研究发现研究区A层高岭石粘土岩中铁质矿物主要是菱铁矿、针铁矿和赤铁矿，且以赤铁矿和针铁矿为主。

Balling and roasting experimental studies were carried out for siderite and limonite concentrate. The results showed that both green ball strength and bursting temperature increased when adding limonite and magnetite into siderite concentrate.

对菱铁矿和褐铁矿精矿进行了造球、焙烧试验研究，结果表明，在菱铁矿精矿中配加褐铁矿的同时配加磁铁矿，既可提高生球强度，又可提高爆裂温度。

Accordingly, want to realize Dong Anshan to contain the effective depart of content of the iron ore in carbonate iron ore and quartz, if where,the key is before turning over floatation, go out siderite depart beforehand, or the floatation drug that find can effective activation or restrains siderite.

因此，要实现东鞍山含碳酸盐铁矿石中铁矿物和石英的有效分离，关键是如何在反浮选之前预先将菱铁矿分离出去，或找到能有效活化或抑制菱铁矿的浮选药剂。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
