查询词典 flotation

The flotation mechanism of MG reverse-floating dolomite was studied by measuring the Zeta-potential of collophanite and dolomite, Infrared Absorptions Spectra analysing the adsorption of MG onto the minerals surface, ultraviolet- visible light absorbing spectrum calculating the amount of MG which was adsorbed onto the minerals surface. These researches showed that MG was more easyly adsorded onto the surface of dolomite in feeble acidic solution because of pure dolomite charges positive as well as pure collophanite charges negative. Therefore, a lot of MG negative ions was adsorded onto dolomite, and that MG negative ions contained hydrophobic group, the hydrophobicity of dolomite was modified, the grains of dolomite were adhered to air bubble and float with them.

对白云石和胶磷矿的Zeta-电位测定、红外光谱分析MG药剂在矿物上面的吸附情况、紫外-可见吸收光谱测定矿物上MG的吸附量等，研究了MG药剂反浮选白云石的浮选作用机理，表明在弱酸性条件下，由于白云石表面荷正电而胶磷矿表面荷负电，带有羧基和羟基官能团的MG药剂更容易吸附在白云石上，使其周围吸附有大量的MG负离子，而MG负离子的另一端为烃基，这就改变了白云石的疏水性，使其矿粒容易附着于气泡上浮。

Fixing flash flotation test scenarios by examine grindstone process and unite stone nature.

通过对磨矿流程的考查，结合矿石的性质，确立了快速浮选的试验方案。

The paper gives an account of the influence of oxidized coal slime on its floatability and the way to improve the performance of flotation treating such slime.

This article has summed up the current researches on separating quartz from feldspar through flotation with no-fluoride, and analyzed the mechanism that causes the differences of floatability between quartz and feldspar in these several processes.

对国内外石英—长石无氟浮选分离的现行工艺进行了系统总结，并对在这几种工艺条件下导致两种矿物可浮性产生差异的内在机理做了具体分析。

This paper attempts to explain floatability classification parameters of coals through the theoretical data of float and sink in comparison with flotation efficiency.

本文嘗試利用煤在重液中分離所得的理論指標與煤的浮選效率的比較關係來探討煤的浮選性分類指標。

Due to its linear chain structure, polyacrylamide, combined with DDA, tends to form the high molecular collector with more surface activities. In addition, with the high molecular weight, polyacrylamides (with the exception of hydroxamic acid polyacrylamide) can strongly flocculate kaolinite, which can increase the adsorptive density of collector and activate the kaolinite flotation.

由于分子的直链结构，聚丙烯酰胺药剂易与捕收剂十二胺形成表面活性更高的高分子捕收剂，同时由于聚丙烯酰胺具有较高的分子量，对高岭石显示很好的絮凝作用，增加了捕收剂的吸附密度，活化了高岭石的浮选。

The beheviour of four low-molecule weight organic acid lactic acid,hydroxy-acetic acid,mercapto-acetic acid,glyconic acid as iron-containing silicate-aegirines depressants on the hematite direct flotation is investigated in this paper.The results of flota

本文研究了四种小分子有机酸抑制剂乳酸、羟基乙酸、巯基乙酸、葡糖酸在赤铁矿正浮选中对含铁硅酸盐脉石霓石的抑制行为，纯矿物、人工混合矿与实际矿石浮选实验均证明了它们具有良好的选择性抑制作用，可以成功地实现赤铁矿与霓石的浮选分离。
