采用化学分析、电子能谱(EDS)、X射线衍射(XRD)和X光电子能谱(XPS)等方法，研究了高炉入炉焦和风口焦中矿物质元素种类、含量、化学形态及物种。研究表明：高炉风口焦与入炉焦相比，矿物质元素种类差别不大，但含量差别较大；风口焦中矿物质物种的区别在于增加了Si、Al、Fe单质和Ba2+的物种。
The chemical states and species of mineral in cokes from different blast furnaces were studied by chemical analysis, EDS, XRD and XPS. The experimental results showed that: Compared with skip coke, the kinds of mineral elements in tuyere coke have no obvious difference, but the contents of mineral elements are different; the chemical states and species of some minerals such as Si， Al， Fe， Ba2+ were also found in tuyere coke.
