Resource recovery from two metallurgical residues by flotation was investigated applying an electrostatic model to select initial conditions. The first, a sulphation roast/water leach residue, was processed to float lead sulphate, comparing dodecylamine and xanthate collectors. From the second, a neutralization residue, gypsum, was recovered by reverse flotation of ferric hydroxide, comparing oleate and sulphonate collectors. In both cases, further upgrading by acid leaching was considered.
通过应用静电模型来选择初始条件，研究了采用浮选法从两种冶金残渣中回收资源的情况。第一种是硫酸化焙烧/水浸残渣，通过比较十二胺和黄药捕收剂来浮选硫酸铅。第二种是中和残渣，通过反浮选氢氧化铁来回收石膏，比较油酸盐和磺酸盐捕收剂。在这两种情况下，都考虑了通过酸浸进一步提纯。
