摘要
摘要 本文介绍了对戈列夫卡矿床两块铅锌矿石样本物质构成的研究。由于方铅矿的细微散布及其与闪锌矿的复杂互生，这两个矿石样本是难找的矿石；其特点是硫化铅部分被角闪石和铈闪锌矿取代；含有柱状方铅矿。对最初的矿石样本进行了 X 射线相位、化学和粒度分析，并对目标元素进行了测定。根据铅回路中粒度品位的变化，在不同的试剂制度下对样品进行了选择性浮选试验，随后对产品进行了电子显微镜检查，证明了试验矿石的加工难度。
Mineralogical Features Associated with Material Constitution and Process Properties of Difficult Lead–Zinc Ore
Abstract
The article describes the studies on the material constitution of two lead–zinc ore samples from the Gorevka deposit. The samples are difficult ore because of fine dissemination of galena and its complex intergrowth with sphalerite; feature partial replacement of lead sulfide by anglesite and cerussite; contain colloform galena. The initial ore samples underwent the X-ray phase, chemical and grain-size analyses, with sizing of target elements. The tests of selective flotation of the samples, with variation of size grade in the lead circuit, in different reagent regimes and with the subsequent electron microscopy of the products proved the processing difficulty of the test ore.
