查询词典 leached

The activated or leached process and their influence elements are studied by 1DREACT software package of coupled mass/heat transfer and chemical reaction dynamics of water-rock interaction, according to the geological and geochemical characters of fine disseminated gold deposits.(1) Water-rock reaction time is not the important influence element of activating gold;(2) At first, activating capability of hydrothermal solution increases with the increasing of total sulfur activity; after lga〓≥-4, the content of activated gold in solution is mainly related to original content of gold in wall rock, and does not visibly dependent on total sulfur activity.(3) It is a complicated nonlinear process of influence of activating gold capacity of hydrothermal solution with the change of temperature, in general, 220 ℃ is most favorable to gold activation.(4) The influence of oxygen fugacity on gold activation has a multiple functions coupling nonlinear effect, in general, Igfo〓=-41 is most favorable to gold activation.(5) Solubility of gold in fluid decreases with the increasing of velocity of flow, the product of velocity and aurous solubility reaches maximum when velocity is 0.2～0.5m〓m〓. yr〓, i. e. this scope of velocity is most favorable to gold activation.

It is convenient for sinter to be leached, and the secondary reaction appears little. The slurry after sinter leaching is transferred into autoclave for desilicification at about 170℃, and the siliceous modulus of solution reaches more than 200. Then some lime is added for deep-desilication at normal pressure, the siliceous modulus of solution increases more than 600 even if the Al2O3 content is more than 200g/L.The SiO2 coefficient in hydrate garnet from deep-desilication is more than 0.28. Under conditions of the addition of seed and application of novel technology of carbonization, the contents of Na2O and SiO2 in product are less than 0.37% and 0.025%, respectively.

The chemical weathering index, K/Na ratio, eluvial coefficientand A-CN-K diagram , can availably indicate the evolution of pedogenic environment. The A-CN-K and CIA-K/Na diagram showed that the Holocene paleosol was in the primary stage of weathering, which K-feldspar went through weak weathering and K was less leached with much leach of Ca and Na. The intensity of weathering went stronger gradually from west to east in the Weihe Valley.

对化学风化指数、K/Na比值、残积系数等化学综合参数的研究结果显示，各项地球化学参数可有效指示成壤环境与成壤强度；从A-CN-K风化趋势图和CIA-K/Na比较图中可知，渭河流域三个剖面风化程度最高的全新世古土壤基本处于同一风化阶段，即脱Ca、Na，尚未到达脱K的阶段，还是风化较弱的初级阶段，但三者的风化程度是存在差异的，风化程度XJN剖面最低，JYC-N剖面最高，ETC剖面介于其中，说明渭河流域自西北向东南风化程度逐渐增强。
