The Humboldt Mill is a historic brownfield site built by Cleveland Cliffs Iron Company in the 1950's for milling of iron ore from their adjacent open pit mine. Cleveland Cliffs ceased operations in the early 1980's and the pit began to naturally fill with water. The property was sold to Callahan Mining Company who began milling.
Mills for ores and minerals. Loesche grinding technology is a dry milling process which offers significant advantages over conventional crushing and grinding technologies in ore beneficiation. Advantages include: Low specific energy consumption; Steep product particle size curve; Reduced product overgrinding; In-bed.
