what do they do at metallic ore mills


Posted on November 19, 2018



Mineral processing - WikipediaBefore the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling". Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973. They were also in use in medieval Persia. By the 11th century, stamp.what do they do at metallic ore mills,Rod Mills - 911 MetallurgistJan 25, 2018 . Rod Mill Grinding.

Sometimes these gangue minerals are of a metallic character like pyrite, but most have a non-metallic character, like quartz. Miners are interested in the minerals that carry the values worth extracting, and often have little interest in those worthless gangue minerals—but as I have noted, they can tell us quite a bit of useful.
