摘要
本文叙述我国岩浆型硫化铜镍矿床中伴生金银含量、赋存状态和地质特征。铜镍矿石中一般Ag高于Au、Au和Ag主要呈独立矿物产出 ,形成自然元素。金属互化物、蹄化物和硫铋化物。共发现24种金和银的独立矿物。(?)(?)(?)金银矿物。矿物颗粒一般为15—60μm。一般来说,铜镍富矿石,特别富铜矿石的AuAg含量要比贫矿石高;晚期热液作用的铜镍矿床其AuAg含量要比单一熔离矿床高。
The contents, occurring state and geological characters of the associated gold and silver in the magmatic type of copper and nickel sulfide deposits in China are discussed in this paper. The content of silver is usually higher than that of gold in copper-nickel ores. Both of them occur as independent mineral, which form native elements, mutual metal compounds, tellurides and sulfobism uthides, twenty kinds of independent gold and silver minerals and seven kinds of gold-and silver-bearing minerals were discovered. The granularity of the minerals is generally 15-60um. Generally speaking, the contents of gold and silver in rich ores of copper and nickel, especially in copper-riched ores is higher than that in copper-nickel-poor ores, and being higher in later hvdrothermal copper-nickel deposits than in simple liquation deposits. The copper-nickel sulfide deposit is an important type deposit with associated gold and silver.
