钖精矿所含大多数金(尸专)元素,在冶炼过程中都被还(厂元)成金(尸专),故所得冶炼产品是粗钖。粗钖中多数金(尸专)杂质(如Fe、Cu、Sb),很容易用大家熟悉的精炼工艺除掉。金(尸专)熔体离心分离技术的发展,使精炼效率大为提高,特别在除铁方(?)。但是铅和铋的分离,直到最近,仍 钖 concentrate contains most of the gold (necropsy) elements, in the smelting process have been (plant yuan) into gold (corpse), so the resulting smelting products are rough 钖. Most of the crude oil (corpse) impurities (such as Fe, Cu, Sb), it is easy to use the familiar refining process to get rid of. Gold (corpse) melt centrifugal separation technology, so refining efficiency greatly improved, especially in the iron side (?). But the separation of lead and bismuth until recently, still
