therefore, both in-plant iron and carbon-containing dust and lime stone dust can improve the firing behavior of the brazilian specularite pellets.
因此,这两种物料都很好的改善了巴西镜铁矿的焙烧性能。
the main metallic mineral is specularite containing native gold and electrum. surbordinate minerals are pyrite, chalcopyrite siderite and a very small amount of sulfosalt.
金属矿物较简单,主要为镜铁矿含自然金和银金矿,次为黄铁矿、黄铜矿、菱铁矿和微量硫盐。
high pure specularite could be produced by flotation method. after fine grinding, it could be used to produce paint filler.
