Because of this close association of zinc and lead ores, it is necessary to consider them together in discussing their concentration. An earlier summary of practices and costs of concentrating lead and zinc ores was published by the Bureau of Mines in 1935. Most of the data in the present bulletin were abstracted from the earlier publication.

When, however, the lead mineral is the only one of importance—and such ores are not uncommon—it is usually extracted by gravity concentration in jigs and on tables, followed, after thickening and grinding if necessary, by the flotation of any middlings and tailings that are too high in lead values to be sent to waste; direct flotation is ...

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
