Based on the characteristics of potash mine in Vientiane of Laos,the author proposes to extract potassium chloride with directional drilling communicated method and selective solution mining method.

作者就老挝万象钾盐矿的特点,提出采用定向钻进连通法,选择性溶解开采工艺开采氯化钾。

The selective dissolution of zinc in brass Cu 32 Zn in acidic sodium sulphate and dilute nitric acid solutions was investigated by galvanostatic polarization and RRDE methods.

采用恒电流Ｅ－ｔ曲线与旋转盘环电极方法研究了α黄铜（Ｃｕ３２Ｚｎ）在酸性Ｎａ２ＳＯ４和ＨＮＯ３稀溶液中的阳极溶解行为，得到的典型Ｅ－ｔ曲线上存在几个特征区，证明在较低电流密度条件下的初始阶段只存在Ｚｎ的选择性溶解。

Thus,it is provedthat the selective dissolution of zinc in brass is controlled by a solid-state diffusion process.

结果表明，在黄铜阳极溶解的初始阶段测得的ｉ－ｔ曲线遵循抛物线定律，求得ｉ－ｔ为一通过坐标原点的直线，证明了黄铜中锌的选择性溶解受固相扩散控制，计算出在上述溶液中黄铜中锌的扩散系数值在１０－１５～１０－１３ｃｍ２·ｓ－１数量级，介质成分和微量合金元素砷对扩散系数值有明显的影响。
