补充资料:冶金熔剂
在火法冶金过程中能与矿石中所含的脉石氧化物、有害杂质氧化物作用,形成低熔点渣层,从而把要提取(精炼)的金属分离开来的物质。熔剂按冶炼过程和阶段可分为熔炼熔剂和精炼熔剂;按熔剂性质可分为碱性熔剂(石灰、石灰石、白云石等)、酸性熔剂(石英、含硅高的有价金属矿石等)、中性熔剂(铝矾土、矾土质有价金属矿石等)和助熔剂(降低炉渣粘度的萤石、熔解Al2O3的冰晶石等)。一般要求熔剂中的有效成分尽可能高,有害杂质含量尽可能低(如炼钢熔剂要求含硫和磷低等),强度和块度(粒度)能满足冶炼工艺要求(如高炉炼铁要求熔剂强度好,大高炉适用块度为20~75毫米,小高炉块度为10~30毫米,有色金属硫化物精矿闪速熔炼要用粉状熔剂等)。
熔剂的选择同要提炼的金属和矿石成分有关。钢铁冶炼常用CaO-Al2O3-SiO2系渣,而铁矿石和焦炭的灰分大多是酸性氧化物(SiO2等),因此主要用碱性熔剂(石灰石或白云石等)。个别情况下冶炼含碱性脉石的铁矿,也用酸性熔剂(石英或含酸性脉石的贫矿)。有色金属冶炼常用FeO-SiO2、FeO-CaO-SiO2和FeO-Al2O3-SiO2系渣,而有色金属矿石和精矿中常伴生有碱性铁矿物、方解石等,因此主要用石英或低品位石英砂金矿为熔剂。如果冶炼含酸性脉石的矿石和精矿,应配加石灰石、铁矿石或含碱性脉石的有色金属矿作熔剂。
