对来自不同冶金工艺的垃圾填埋场矿渣样品进行了表征。根据渣中铬含量和碱度的不同，将渣分为电弧炉渣、氩氧脱碳/精炼工艺渣和真空氧脱碳渣。由于电弧渣的铁和铬含量较高，其金属回收潜力比其他两种渣高。铁铬镍合金颗粒的大小从几μm到几厘米不等。大金属颗粒和金属尖晶石集合体的回收有可能使从填埋炉渣中回收金属在经济上可行。
The slag samples taken from landfill, which originated from different metallurgical processes, have been characterized in this study. The slags were categorized as electric arc furnace (EAF) slag, argon oxygen decarburization/metal refining process slag and vacuum oxygen decarburization slag based on chromium content and basicity. EAF slags have higher potential in metal recovery than the other two slags due to its higher iron and chromium contents. The size of the iron-chromium-nickel alloy particles varies from a few μm up to several cm. The recoveries of large metal particles and metal-spinel aggregates have potential to make the metal recovery from landfilled slags economically viable.
