A study was conducted on the process mineralogy of an oxidized silver-bearing ore in Henan Province.The results showed that the ore had a silver grade of 211.00 g/t,a lead grade of 0.34 %,and a sulfur grade of 0.18 %;the silver minerals were mainly silver-bearing tetrahedrite,freibergite,and native silver,followed by argentite,with a particle size mainly distributed in the range of 0.010-0.074 mm and mainly embedded in fissures and inter-granular spaces of vein minerals;the lead minerals were mainly galena and lead oxide,with a lead oxidation rate of 38.24 % and a higher degree of oxidation,and the particle size was mainly distributed in the range of 0.010-0.053 mm.This ore belongs to a refractory oxidized lead-bearing silver ore with low sulfide content.
