The primary manufacture of lead involves three stages: a) ore concentration b) smelting c) refining (a) Ore concentration. Lead and zinc ores (usually sphalerite, ZnS) often occur together and may also contain silver, copper and gold. The ore has first to be separated from clays and other silicates ('gangue') after which the lead ore and the zinc ore are separated.
