The ore is METALLURGY. 199 first crushed rather fine, and then passed through a 5-footHuntington mill. [See Fig. 63.] The pulp passes through aconcentrating plant, having a capacity of from i to 2 tons perhour, depending upon the gangue. The plant consists of fivebumping-tables, the pulp going first to one table and from thisis divided over the four other bumping-tables. The tailingsare elevated and sized.
