用酸能快速分解试样,所以分析含锌矿物时,通常采用王水或先用盐酸后用硝酸分解试样,而含硫高的矿物试样,则采取先灼烧后再用碱熔,手续较繁。由以往试验结果表明,即使用碱分解含铅锌量高的方铅矿试样,仍有部份硫化锌析出,严重影响测定结果。本文对单矿物和含硫高的多金属矿物试样中测定锌的
Acid can quickly decompose the sample, so the analysis of zinc minerals, usually using aqua regia or hydrochloric acid with nitric acid after the first decomposition of the sample, and high sulfur mineral samples, then take the first burning after alkali melting, More complicated procedures. The results of the previous tests show that even if alkali is used to decompose galena samples containing high amounts of lead and zinc, some zinc sulfide is still precipitated, seriously affecting the determination results. In this paper, the determination of zinc in single-mineral and high sulfur-containing polymetallic mineral samples
