本文提出复杂铜矿物相分析的修订方法。用硷性酒石酸盐溶液溶解孔雀石,用同一试剂及氧气溶解赤铜矿,用硫酸铁溶解辉铜矿之半,用硫酸银溶解另一半辉铜矿及斑铜矿,最后用王水溶解黄铜矿。本法除个别情形外,一般组份均直接测定而无须间接计算;避免反应程度不固定的反应;不用剧毒的氰化钾;亦解决象闪锌矿、方铅矿及黄铁矿等伴生矿物的干扰;而结果比现用方法可靠。
This paper presents a revised method for complex copper mineral phase analysis. Dissolve malachite with the same reagent and oxygen, dissolve half of the chalcocite with ferric sulfate, dissolve the other chalcocite and burkese with silver sulfate, and finally dissolve the malachite with aqua regia Copper mine. In addition to the individual cases of this Act, the general components are determined directly without indirect calculation; to avoid the reaction is not a fixed reaction; do not use toxic potassium cyanide; also solve like galena, galena and pyrite and other associated Mineral interference; and the results than the current method of reliable.
