Trout manganese mill

The Trout Manganese mill, built under the supervision of Roy Hamilton in the early 1950's, was burned down by vandals, or else carelessly, by partiers, last week. Here's a Lee Silliman picture taken just a few weeks ago. The mill processed manganese dioxide ore into several products, using both gravity concentration (jigging) and dry magnetic separation. High grade concentrates were shipped to battery companies because the manganese dioxide was battery active. Philipsburg was the only US district to produce this high grade material. Lower grade material was shipped to the Bunker Hill smelter to use in zinc refining. The mill produced into the 1960s.
