[0023] The specific process is as follows:
[0024] (1) Perform zinc roughing on the lead-selected tailings, add lime to adjust the pH of the pulp to 10.5, and the concentration of the pulp to 38%, add copper sulfate at 300g / t, stir for 5min, and adjust the potential of the pulp to 220-280mV (rel...
