Abstract
An improved process for the mechanical separation of complex, intergrown ores containing mineral of at least one of lead or zinc comprises a differential flotation process followed by an agglomeration process. The improved separation process is useful for bulk separation of mixed, intergrown minerals or for separation of one mineral from another, e.g., separation of lead-containing mineral from zinc-containing mineral.
