Milling of Amenable Gold Ores | SpringerLink

Abstract. The objective of milling gold ores is to extract the gold for the highest financial return. To recover the maximum amount of gold, the ore must be finely ground in order to liberate the gold particles for gravity separation and/or chemical extraction. Ores yielding acceptable gold recovery (more than 88%) when "normally ground ...

This mill pulverized the large chunks of ore that came directly from the mine. Edison planned to process 1200 tons of iron ore every twenty hours. The plant had three magnetic separators that could produce a total of 530 tons of refined ore. There was other equipment to rerefine what was left over to extract even more ore.

Special bacteria are sometimes used as part of this process. After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal. William Andrew Hustrulid

A runofmine (ROM) ore milling circuit is primarily used to grind mined ore containing valuable metals into a very ne product. The ne material is sent to a downstream process after grinding to separate the valuable metal from the gangue material. The separation process results in a concentrate of valuable metals, and a tailings stream of waste.
