A kind of silver concentrate in Henan Province has the associated lead therein with an average grade around 7%, lower than the grade for pricing. A classification test was conducted with a hydrocyclone for the silver concentrate, and effects of parameters, including cone angle, underflow orifice diameter, and angle-cone ratio, on the classification and concentration of silver concentrate were explored. It is found that by adopting a 100 model hydrocyclone with cone angle of 60°, feed in a mass fraction of 13.89% to be fed at the pressure of 0.2 MPa, overflow pipe of 22 mm in diameter, and the underflow orifice of 12 mm in diameter, a high-lead silver concentrate grading 6316.29 g/t Ag and 12.39% Pb can be obtained at corresponding recoveries of 79.06% Ag and 79.45% Pb, with a yield of 49.25%; meanwhile, a low-lead silver concentrate with silver grade of 1 623.36 g/t can be obtained. This processing technique can obtain both high-and low-lead silver concentrate at the same time, leading to the economic value of the silver concentrate improved by 687.96 Yuan per ton.
