1. the method that silver is reclaimed in chemical activation flotation from the navajoite of argentiferous, it is characterised in that comprise the following steps:

  • (1) by broken for the navajoite of argentiferous, fine grinding, particle diameter is made to account for more than 60% at below 0.074mm;

    (2) adding appropriate sodium carbonate, waterglass, fatty acid and water in the navajoite of the argentiferous after fine grinding and carry out pulp, flotation removes calcium mineral, obtains silver vanadium concentrate;

    (3) silver vanadium concentrate mixes with sulphuric acid and carries out sulfuric acid activated process, obtains modifiying slag;

    (4) modified slag is added water and dispersant to carry out dispersion and size mixing, and add activator, collecting agent, foaming agent carry out floating and enriching silver, obtain silver preparation concentrate.
