簡介:"礦物硫化物及硫鹽黃銅礦Chalcopyrite Sulfides and SulfosaltsChalocoprite consists of three elements: copper, iron, and sulfur and usually a small amount of silver, gold, manganese,arsen (As),selenium (Se) and tellurium(Te). Pure chalcopyrite has the brass yellow color, readily tarnishing to copper green when exposed to the air and weathering. Chalcopyrite and pyrite are much alike, but chalocoprite is more yellowish and lower in hardness. The black-green streak can be used for identification. Chalocopyrite is one of the widely distributed minerals; meanwhile, it is an important source for refining copper.主要由銅、鐵、硫三種元素所構成,並常含有少量的銀、金、錳、砷(As)、硒(Se)和碲(Te)。新鮮表面呈銅黃色,若暴露潮濕空氣過久,會風化變為青銅色。 黃銅礦與黃鐵礦十分相似,但顏色偏黃,硬度稍低,條痕為帶綠的黑色可相互區別。黃銅礦是含銅礦物中分布較廣的一種礦物,同時,也是提煉銅的重要來源。"
