Separating Pyrite & Blende Magnetism
At The Yak Mill, Leadville, Colorado, International separators are employed to separate magnetic blende. The ores treated at this mill carry blende, pyrite and pyrrhotite and, as nearly as can be learned, carry from 20 to 30 per cent. zinc. The ore is treated raw, the blende being recovered as a magnetic product.
