广东某金矿矿床的金矿石中的金往往存在于复合矿石中,不仅黄金具有工业价值,其伴生金属元素也有综合利用可能。通过选矿试验表明,不仅金、银得到回收;铅、锌、镉、硫等伴生金属也可以综合回收利用。该矿床为蚀变破碎带类型金矿、花岗变质,中低温热液充填硫化矿床。其中主要金属矿物有银金矿、方铅矿、闪锌矿、黄铁矿等;此外还有微量黄铜矿、辉银矿等。脉石矿物有石英、绢云母等。金的原矿品位一般为0.6—5克/吨,伴生铅、锌较高,各个矿体中往往又分别达到工业指标,因此具有综合利用价值。
The gold in the gold ore of a gold deposit in Guangdong is often found in composite ores. Not only gold has industrial value, but also its associated metal elements may be used in a comprehensive manner. Beneficiation tests show that not only gold and silver are recovered, but also associated metals such as lead, zinc, cadmium and sulfur can also be recycled comprehensively. The deposit is alteration crushing zone type gold deposit, granite metamorphism, medium and low temperature hydrothermal filling sulfide ore deposits. One of the main metal minerals are silver gold, galena, sphalerite, pyrite, etc .; in addition to trace chalcopyrite, glitter and so on. Gangue minerals quartz, sericite and so on. Gold ore grade is generally 0.6-5 g / t, accompanied by lead, zinc higher, often in various ore bodies respectively to achieve industrial targets, and therefore has the value of comprehensive utilization.
