Replenishment of mineral resources, especially gold and rare metals, is critical for progress in the mining and metallurgical industry of Eastern Kazakhstan. To substantiate the scientific background for mineral exploration, we study microinclusions in minerals from gold and rare-metal fields, as well as trace-element patterns in ores and their hosts that may mark gold and rare-metal mineralization. The revealed compositions of gold-bearing sulfide ores and a number of typical minerals (magnetite, goethite, arsenopyrite, antimonite, gold and silver) and elements (Fe, Mn, Cu, Pb, Zn, As, and Sb) can serve as exploration guides. The analyzed samples contain rare micrometer lead (alamosite, kentrolite, melanotekite, cotunnite) and nickel (bunsenite, trevorite, gersdorffite) phases and accessory cassiterite, wolframite, scheelite, and microlite. The ores bear native gold (with Ag and Pt impurities) amenable to concentration by gravity and flotation methods. Multistage rare-metal pegmatite mineralization can be predicted from the presence of mineral assemblages including cleavelandite, muscovite, lepidolite, spodumene, pollucite, tantalite, microlite, etc. and such elements as Ta, Nb, Be, Li, Cs, and Sn. Pegmatite veins bear diverse Ta minerals (columbite, tantalite-columbite, manganotantalite, ixiolite, and microlite) that accumulated rare metals late during the evolution of the pegmatite magmatic system. The discovered mineralogical and geochemical criteria are useful for exploration purposes.

哈萨克斯坦东部金和稀有金属矿化的矿物示踪剂

补充矿产资源,特别是黄金和稀有金属,对于哈萨克斯坦东部采矿和冶金工业的进步至关重要。为了证实矿物勘探的科学背景,我们研究了金矿和稀有金属矿产中的微量元素夹杂物,以及矿石和其宿主中可能标记金矿和稀有金属矿化的痕量元素形态。所揭示的含金硫化物矿石和许多典型矿物(磁铁矿,针铁矿,毒砂,锑矿,锑矿,金和银)和元素(铁,锰,铜,铅,锌,砷和锑)的组成可作勘探指南。分析的样品包含稀有的微米级铅(铝铁矿,方铁矿,黑铁矿,白云母)和镍(铜锌矿,钙钛矿,硅镁铁矿)相以及附属的锡石,黑钨矿,白钨矿和微晶。矿石带有天然金(含Ag和Pt杂质),可通过重力和浮选法浓缩。可以从矿物组合物的存在来预测多级稀有金属伟晶岩的矿化作用,这些矿物组合物包括裂解石,白云母,锂云母,锂辉石,钙铝石,钽铁矿,微晶石等,以及诸如Ta,Nb,Be,Li,Cs和Sn等元素。伟晶岩脉中携带着多种钽矿物质(钴矿,钽铁矿,钴锰矿,锰锰矿,硅镁矿和微岩),这些矿物在伟晶岩岩浆系统演化的后期积累了稀有金属。发现的矿物学和地球化学标准可用于勘探目的。可以从矿物组合物的存在来预测多级稀有金属伟晶岩的矿化作用,这些矿物组合物包括裂解石,白云母,锂云母,锂辉石,钙铝石,钽铁矿,微晶石等,以及诸如Ta,Nb,Be,Li,Cs和Sn等元素。伟晶岩脉中携带着多种钽矿物质(钴矿,钽铁矿,钴锰矿,锰锰矿,硅镁矿和微岩),这些矿物在伟晶岩岩浆系统演化的后期积累了稀有金属。发现的矿物学和地球化学标准可用于勘探目的。可以从矿物组合物的存在来预测多级稀有金属伟晶岩的矿化作用,这些矿物组合物包括裂解石,白云母,锂云母,锂辉石,钙铝石,钽铁矿,微晶石等,以及诸如Ta,Nb,Be,Li,Cs和Sn等元素。伟晶岩脉中携带着多种钽矿物(钴矿,钽铁矿,钴锰矿,锰锰矿,异辉石和微岩),这些矿物在伟晶岩岩浆系统演化的后期积累了稀有金属。发现的矿物学和地球化学标准可用于勘探目的。和微岩)在伟晶岩岩浆系统演化的后期积累了稀有金属。发现的矿物学和地球化学标准可用于勘探目的。和微岩)在伟晶岩岩浆系统演化的后期积累了稀有金属。发现的矿物学和地球化学标准可用于勘探目的。
