| Abstract Scope |
For the rational and efficient comprehensive utilization of an Ag-Mn mine in Mexico. Chemical analysis, scanning electron microscopy, BPMA, and other methods were used to conduct mineralogical research on ore processes. The grade of Ag is 372.3 g/t, which mainly exists in the isomorphic or adsorbed state in psilomelane and other minerals (71.69%). Secondly, it exists in the form of the independent mineral argentite (22.11%). The Mn content is 8.13%, mainly distributed in psilomelane, coronadite, and pyrolusite, accounting for 83%. The process of "high-intensity magnetic separation-regrinding floatation-high intensity magnetic separation" is determined through experimental research. A silver concentrate can be obtained with 869.90 g/t Ag, 25.22% Mn, 62.14% Ag recovery, and 82.92% Mn recovery. The research results have guiding significance in further improving the beneficiation index of this type of ore and exploring and optimizing on-site production. |
