Crusher machines break the ore down into nine millimetre rock sizes, then grinding mills further reduce it to 45 microns – just big enough for the eye to see. After crushing and grinding, the saleable zinc-lead product is separated from waste rock through a …

Zinc processing

Zinc processing - Ores, Refining, Alloying: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world's output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a …

RecoDust—An Efficient Way of Processing Steel Mill Dusts

As a reusable secondary raw material resource, the steel mill dust contains a high amount of iron and zinc. Nowadays, most of the steel mill dusts are processed under the Waelz-Process. However, this process is limited or impossible without additional dust treatment and can only be operated economically with zinc contents over 20 wt%.
