矿床产于近地表处。矿石呈黑褐色,土状,主要由铁的氢氧化物、锰的氢氧化物、石英、粘土等矿物组成。矿石中含金、银、铜、铅、锌、镓、铟、锗、镉、碲等有用元素,其品位接近综合利用要求。它们的赋存状态如下: 金、银的赋存状态:除可见少量独立矿物外,金主要呈吸附状态,次为机械杂质(显微粒)包裹状态。银主要呈显微机械杂质包裹状态,次为吸附状态。金的主载体是铁的氢氧化物,银的主载体是锰的氢氧化物。铜、铅、锌的赋存状态:除可见独立矿物外,绝大多数的铅锌呈类质同象置换的方式存于铁、锰的氢氧化物中。绝大多数的铜呈吸附方式存于铁、锰氢氧化物中。镓、铟、锗、镉、碲的赋存状态:未见独立矿物,它们呈细分散状态,以吸附方式赋存于载体矿物中。镓的主要载体是粘土和铁的氢氧化物,铟、锗、碲的主要载体是铁的氢氧化物,镉的主要载体是锰的氢氧化物。综上所述,有用元素(除镓外),主要呈细分散状态载负于铁、锰的氢氧化物中,在选矿流程中上述伴生元素将随铁、锰矿物的富集而相对富集,但若从铁、锰矿物中分离出上述元素,则须采用化选或冶炼方法甚至更为复杂的方法,才能分别回收。
Deposits produced near the surface. Ore was dark brown, earthy, mainly by the iron hydroxide, manganese hydroxide, quartz, clay and other minerals. Ore contains gold, silver, copper, lead, zinc, gallium, indium, germanium, cadmium, tellurium and other useful elements, its grade close to the comprehensive utilization requirements. Their occurrence status is as follows: gold, silver occurrence state: in addition to visible a small number of independent minerals, the gold was mainly adsorbed, followed by the mechanical impurities (microparticles) wrapped state. Silver was mainly micro-mechanical impurities wrapped state, times for the adsorption state. The main carrier of gold is iron hydroxide, the main carrier of silver is manganese hydroxide. Copper, lead, zinc occurrence state: In addition to the visible independent minerals, the vast majority of lead and zinc were wasomorphic way stored in iron, manganese hydroxide. The vast majority of copper is adsorbed in iron, manganese hydroxide. Ga, Indium, Germanium, Cadmium, Tellurium Occurrence state: no independent minerals, they were finely dispersed state, the adsorption occurs in the carrier minerals. The main carriers of gallium are the hydroxides of clay and iron, indium, germanium, the main carrier of tellurium being iron hydroxides, and the major carrier of cadmium being manganese hydroxides. In summary, the useful elements (except gallium) are mainly supported in finely dispersed states in iron and manganese hydroxides. In the beneficiation process, the associated elements will be relatively enriched with the enrichment of iron and manganese minerals However, if the above elements are separated from iron and manganese minerals, they should be recovered separately by the selective or smelting method or even more complicated method.
