The cumulative zinc recovery increased rapidly in the first 50 s followed by a relatively slow improvement. About 90% of zinc was recovered after 4 min of flotation while about 80% recovery was achieved in the first 75 s, with the zinc grade above 40%. Based on the flotation rate test results, a staged roughing flotation strategy was proposed.
