以褐铁矿为主体的多金属低品位锡中矿,用煤气为热源在回转窑内进行氯化焙烧时,锡、铅、砷等均可彻底挥发脱除,其残量在所产含铁50％左右的焙球中皆符合炼铁要求,唯铜、锌较高且焙球强度过低,不能直接用作高炉原料,为使氯化焙球有一经济合理的利用途径,曾进行多方案研究。我们依据中矿氯化焙球的理化特性和铜、锌、银等选择氯化挥发的理论分析,以及所
The limonite as the main multi-metal low-grade tin in the mine, the use of gas as a heat source in the rotary kiln chlorination roasting, tin, lead, arsenic, etc. can be completely volatile removal of the remaining iron content in the production of iron About 50% of the baking balls are in line with the requirements of ironmaking, copper and zinc only, and the baking ball strength is too low, can not be directly used as a blast furnace raw material, in order to make the baking of chlorine ball has a reasonable and economical use of the route, the study. We based on the physical and chemical properties of chlorinated baking balls in the mine and copper, zinc, silver and other selected chlorinated volatile theoretical analysis, and
