Abstract
- Phase analysis of silver in ores refers to the determination of the content of silver in various host minerals. Through experimental analysis, it is established that the main silver phases in the ore include 6 types: silver in smithsonite, silver in minerals bearing iron and manganese, native silver, silver sulfide, silver in iron oxides, and silver in silicates. Acetic acid is used to leach silver from smithsonite, sodium chloride - hydroxylamine hydrochloride is used to leach silver from minerals bearing iron and manganese, ferric nitrate solution is used to leach native silver, thiourea - sulfuric acid solution is used to leach silver sulfide, hydrochloric acid - stannous chloride is used to leach silver from iron oxides, and the remaining residue is measured for silver in silicates. The relative standard deviation of this method for determining each silver phase ranges from 0.22% to 5.36%. The sum of the silver content from each phase closely matches the total silver content measured, indicating that the phase separation method is correct and the test results are accurate.
