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。

The Ageenkov's acheme[1] of phase analysis of complicate copper ores hae the dieadvantages that (1) most components are not determined directly but calculated fxom a sezies of simultaneous equations, (2) some methods are based upon non-etoichiometric reactions,(3) it necessitates the use of potassium cyanide and (4) it neglects the interference of accompanying minerals, such as sphalerite,galena,pyrite etc.
