Zinc is obtained from complex ores containing 1–4 percent zinc in the form of a sulfide, as well as Cu, Pb, Ag, Au, Cd, and Bi. These ores are concentrated by selective flotation, yielding zinc concentrates containing 50–60 percent zinc, as well as lead, copper, and sometimes pyrite concentrates.

First there is a deduction from the contained metal assay to compensate the smelter for processing metal losses. If the concentrate grades around 50% lead and 20% zinc, then around 3% of the lead and 8% of the zinc will be deducted. This is effectively part of the treatment fee and is usually higher for lower grades.

Sulfides are generally fairly dense and heavy, so they can be recovered by simple gravity methods. Vibrating tables are sometimes used for this purpose and the sulfides will usually show up in the table middlings. However, in most commercial milling operations, sulfides are recovered by a method called flotation.
