In the course of groundwater towards the center of the depression cone, not only the dissolution of calcite, dolomite and hematite, the precipitation of siderite and melanterite may occur, but also the cation exchange between Na+ and Ca2+, Fe oxidation- reduction of Fe may occur.

地下水在向降落漏斗中心区的径流过程中，不但发生了方解石、白云石和赤铁矿的溶解作用以及菱铁矿和水绿矾的沉淀作用，而且发生了Na+与Ca2+的交换、铁氧化-还原反应等一系列复杂的水-岩作用。

In the course of groundwater towards the center of the depression cone, not only the dissolution of calcite, dolomite and hematite, the precipitation of siderite and melanterite may occur, but also the cation exchange between Na(superscript +) and Ca(superscript 2+), Fe oxidation-reduction of Fe may occur.

地下水在向降落漏斗中心区的径流过程中，不但发生了方解石、白云石和赤铁矿的溶解作用以及菱铁矿和水绿矾的沉淀作用，而且发生了Na与Ca(上标 2+)的交换、铁氧化－还原反应等一系列复杂的水－岩作用。

The result makes clear, can be restrained on certain level by starch but the siderite with weaker inhibition in hematite and quartz exterior adsorption overspreads a lid, it is the main reason that causes Dong Anshan to contain carbonate iron ore to turn over floatation difficulty.

结果表明，可在一定程度上受到淀粉抑制但抑制功能较弱的菱铁矿在赤铁矿和石英表面的吸附罩盖，是引起东鞍山含碳酸盐铁矿石反浮选困难的主要原因。

"It occurs rarely as a free metal, occasionally in natural alloys, and in hundred s of minerals and ores, including hematite, magnetite, limonite, and siderite."

地壳中游离铁很少见，而通常存在于合金及数百种矿物中，包括赤铁矿、磁铁矿、褐铁矿和菱铁矿。

The depressive behavior of (NH4)2 SiF6 on iron-containing silicate gangue, aegirine, in hematite flotation with sodium oleate as collector was studied.

研究了油酸钠为捕收剂的赤铁矿浮选中，水玻璃与氟化物等抑制剂对含铁矽酸盐脉石矿物霓石(NaFe2 SiO6)的浮选抑制行为。

It demonstrated that the hydroxy organic acids substituted with-OH,-SH at α—C such as lactic acid, Hydroxy-acetic acid, mercapto-acetic acid, glyconic acid have good selectivity for separation of hematite and aegirine pka values of organic acids fall down because of the-I inductive effect of-OH or-SH, and lie at the pH range between two minerals point-zero-charge. As a result, the depression ability of them was enhanced, and a cyclo-pentyl chelate was formed when this organic acids acted with Fe〓 on the minerals surface.

发现在α位具有-OH、-SH等取代基的短链一元羧酸（乳酸、羟基乙酸、巯基乙酸，葡萄糖酸）对赤铁矿与钠辉石的浮选分离具有优良的选择性抑制作用，-OH、-SH的-I诱导效应导致有机酸的pKa值下降并落在两种矿物零电点之间，使其抑制性能增强，并与矿物表面的Fe〓形成稳定的五元螯合环。

The A and B components remanent magnetization were loaded by goethite and maghemite respectively, the C component remanent magnetization was carried by the magnetite in the sandstones and were loaded conjunctly by the magnetite and hematite in the mudstones and muddy sandstones.

它们的存在并不影响岩石原生剩磁的分离，也不影响原生剩磁信号的稳定性和获得的古地磁数据的可靠性。16个砂岩采点中不能分离出C分量，是由于后生的赤铁矿彻底改变了由磁铁矿携带的原生剩磁组分，在高密度采样的情况下剔除这些采点并不影响古地磁极性柱的构建和解释。

It sense d a min eral called hematite that offen forms under wet conditions.

它还发现了被称为赤铁矿的矿石的存在，这种矿石通常是在潮湿条件下形成。
