Percolation leaching method Keyes, Harmon E.

A method of leaching ores comprising grinding the material, regulating the water content thereof so as to permit agglomeration of the smaller particles on the larger particles, agitating the mass so as to adhere the smaller particles to larger units to form individual agglomerates, then depositing on the charge of agglomerated material a layer

Extractive Metallurgy of Nickel, Cobalt and Platinum Group

The purpose of grinding is to produce particles that are "liberated," that is, small enough to consist mostly of one mineral. The liberated particles can then be separated by flotation into two streams—a nickelrich concentrate consisting of pentlandite and a nickellean waste stream, consisting of pyrrhotite and gangue rock.
