原矿

When it is crashed to -3 mm and is mixed uniformly it will become the sample for multi-elements analysis raw ore screening and elutriation raw ore mineralogy research and gravity concentration test.

试验矿样取自选矿生产现场，经破碎至-3毫米，均匀混样后作为本次试验的多元素分析样品、原矿筛分及水析样品、原矿矿物学研究样品和重选试验样品。

According to craft mineralogical research result, use raw ore to wait for sulfide via floatation eliminate realgar, gamboge first, soak of the cyaniding after floatation concentrate pretreatment, the plan of direct cyaniding soak undertakes floatation gangue experiment, total soak rate of gold is achieved 88.52%, relatively raw ore is direct soak of complete mud cyaniding increases 25.02 percent.

根据工艺矿物学探究结果，采用原矿先经浮选除去雄黄、雌黄等硫化物，浮选精矿预处理后氰化浸出，浮选尾矿直接氰化浸出的方案进行试验，金的总浸出率达到88.52%，较原矿直接全泥氰化浸出提高25.02个百分点。

Processing method: ore, ore crushing, washing, water mill, dry mill and so on.

加工方式：原矿、原矿破碎、水洗、水磨、干磨等。

But also should see, our country basically is hold the market with cheap raw ore, lump raw ore exports a quantity to occupy the 95 ％ above that always speaks a volume, the 1／ that average price is price of farinaceous product export only 2, under Moroccan export price, the price that compares Euramerican country is lower.

但是也应该看到，我国主要是以廉价的原矿占据市场，块状原矿出口量占总出口量的95％以上，平均价格只是粉状产品出口价格的1／2，低于摩洛哥的出口价格，比欧美国家的价格更低。

The physicochemistry properties of the raw ore and its meaning on geochemistry The earthy black weathered mineral has strong oxide-reducing and acid-base activites. When it reacts with hydroxylammine hydrochloride and inorganic acid, the large number of RE and pb in it can be dissolved in aqueous solution.

原矿的物理化学性质及地球化学意义黑色土状风化物具有较强的可还原性和酸碱活性，它对稀土和Pb等的吸持作用受环境pH值和氧化还原电势影响很大，其中的稀土和Pb可在原矿与还原性物质和酸性物质反应时被溶解出来。

Solid state reduction of raw titaniferous magnetic ore, its sinter , and pellets with H_2 and CO have been studied at various temperatures.

用CO和H_2为还原剂研究了钛磁铁矿原矿，烧結矿和球团矿的还原性。

The technological processes of raw ore direct acid-leaching,raw ore salt roasting-water leching or acid leaching and raw ore salt roasting-acid pelletizing curing-acid leaching,etc.

原矿加盐焙烧水浸或酸浸；原矿加盐焙烧一拌酸制粒熟化酸浸等工艺过程。

Research of minerals processing experiment suggested a flotation flowsheet,which consists of selective flotation of molybdenum sulfide using kerosene as collector,sodium-silicate as dispersant of slimes,then flotation of molybdenum oxide using modified sodium-silicate as depressant of gangue,Rt as collector.

研究表明，以水玻璃为矿泥分散剂、煤油为捕收剂浮选硫化矿，以改性水玻璃为脉石抑制剂、RT为氧化钼矿捕收剂优先浮选硫化矿再浮氧化矿，可从含Mo 0.34%原矿中，获得品位46.41%的硫化钼精矿，品位27.65%的氧化钼精矿；钼总回收率78.01%。

The strain JXF-1 had the maximum efficacy of releasing silicon in the tested strains from different resources, it can release respectively silcon 50.4% and 65.3% from raw bauxites and artificial mixed chlorites, but for strain B.

其中JXF-1菌株脱硅效果最好，可以浸出铝土矿原矿、绿泥石人工混合矿样中50.4%与65.3%的硅，而B.C菌株对该两种矿样的脱硅率仅分别为35.3%，48.2%。

This kind of sulfide ore is relatively refractory and it is difficult to improve production ibexes, with high cost and low benefit. During 1988 to 2000, the per-product ability is 157.5 ton per day, primitive mineral tin grade is 1.89% and obtained 52~54% tin concentrated, with 51.06% recovery. Tin grade of 1.5% make mining and processing keep equal.

这种硫化矿比较难选，生产指标一直难以提高，处理该类型矿石生产指标低，成本高，效益差。1998年至2000年的三年间，平均生产能力157.5吨／日，原矿锡品位1.89％，产出的锡精矿含锡52～54％，锡回收率51.06％，原矿采选持平锡品位为1.5％。
