江西德兴铜厂斑岩铜矿为一超大型铜矿床,除含铜外,还伴生有金、银、钛、钼、硫、钴、镍及稀有分散元素铼、镓,硒、碲等。由于金的赋有状态不清,铜厂选矿厂在选铜、钼时只能回收部分金。经过岩矿鉴定、重砂分析、氢氟酸溶解、化学物相分析、光谱、电子探针、磨浮试验等工种密切配合,相互验证,对金的赋存状态基本查清,为综合评价提供了依据。此文仅在金的赋存状态研究结果及方面予以叙述。
Jiangxi Dexing copper plant porphyry copper deposit is a super-large copper deposit, in addition to copper, but also associated with gold, silver, titanium, molybdenum, sulfur, cobalt, nickel and rare dispersing elements rhenium, gallium, selenium, tellurium, etc. . As the endowment of gold is unclear, copper concentrator in the election of copper, molybdenum can only be recovered part of the gold. After rock and mine identification, heavy sand analysis, hydrofluoric acid dissolution, chemical phase analysis, spectroscopy, electron probe, grinding test and other work closely with each other, verify each other, the basic state of gold found, for comprehensive evaluation The basis. This article is only described in the findings and aspects of the state of the occurrence of gold.
