Cy alkaline pretreatment for refractory gold floatation concentrate of anidation tailings under normal temperature and pressure 难浸氰化尾渣浮选精矿的常温常压碱浸预处理
The floatation concentrate of anthracite ( ant ) was heat - treated with different maximum heat treatment temperature ( httmax ) . the microstructures of the samples heat - treated with different httmax were characterized by their densities and xrd spectra 将无烟煤( ant )的浮选精矿进行不同最高热处理温度( htt _ ( max ) )的热处理,用密度和xrd图谱来表征热处理后ant试样的微观结构。
