Democratic Sentinel, Volume 15, Number 42, Rensselaer, Jasper County, 6 November 1891 — Magnetic Concentrator. [ARTICLE]
Magnetic Concentrator.
A new ore concentrator has been devised, which operates by crushing the material to about a quarter of an inch in size, and which, exposed to the action of powerful magnets, separates the particles of iron ore. These articles of ore are again crushed to a finer state, and again exposed to magnetic action, resulting in a concentrated condition of the iron. The older a man grows the wiser he usually becomes, unless he happens to marry a young wife.- Hew York Benorder.
