广东省西部新榕锰矿矿石中含银较高 ,平均达到 10 0× 10 - 6以上。利用电子探针等测试方法对锰矿石中伴生银的赋存状态进行研究 ,初步查明银主要是以脆银矿、溴角银矿、银锑黝铜矿、银金矿等矿物形式存在 ,呈微小颗粒状被包裹于铁锰矿物内或矿物间隙里。少部分的银可能以吸附离子形式存在于铁锰矿物中 The ore of Xinrong manganese ore in western Guangdong Province has a high content of silver, with an average of more than 10 × 10 - 6. The existence of associated silver in manganese ores was studied by using electronic probes and other test methods. The results showed that the silver mainly existed in the form of silver, bromocrotyl silver, silver antimony tetrahedrite, silver and gold minerals, Was tiny particles were wrapped in ferromanganese minerals or minerals in the gap. A small portion of the silver may exist as adsorbed ions in the ferromanganese
