Silver Lead Zinc Ore Processing Method using Flotation

The process consists of selective flotation to produce a mixed silverlead concentrate for maximum smelter return and a separate zinc concentrate. Overgrinding of silver minerals is detrimental to efficient flotation recovery, so the Flash Flotation UnitCell is used in the grinding circuit to recover a large part of the silver and lead values as soon as liberated.
