| Abstract: | The process principle and main influence factors of separating Mn-Ag oxidation ores with low molecule hydrocarbon were investigated.When controlling leaching rate of Mn to 96%,the leaching loss rate of Ag is less than 2%.Cyanidation is employed for Ag extraction in leaching Mn residues and the leaching rate of Ag is more than 93.41% when the dosage of NaCN is 1 kg/t residues and leaching time 3 h.The recovery of Ag leached by two-step of leaching Mn-cyanidation is more than 91.54%,Mn and Ag are effectively ... |
