Silver Ore Beneficiation : How to effectively separate silver-lead concentrate?
Silver-lead concentrate is an intermediate product obtained through beneficiation processes from lead ores containing silver or lead-silver co-occurring ores. It is an important raw material for the smelting of silver and lead. Among this type of minerals, silver mostly exists in the form of natural silver and silver sulfide, while lead is mostly found in galena. In ores with a higher degree of oxidation, it may also exist in the form of cerussite and anglesite. This article will introduce how to separate silver-lead concentrate....
