Basicity and acidity of slag is a quantity that characterizes the strength of the basicity and acidity of slag The basicity of slag is generally expressed by the ratio of basic oxide content to acidic oxide content in slag The reciprocal of basicity R=frac{sum mathrm{basic} mathrm{oxide}}{sum mathrm{acidic} mathrm{oxide}} is
1 Introduction Converter steelmaking slag CSS is a by product discharged by the converter steelmaking process which brings the leaching risks of heavy metals [1] CSS is mainly stored in artificial dam because only minority CSS is utilized by the current research methods [2] However this storage pathway of CSS not only occupies many land but also
