Advantages of grate kiln

Jan 22, 2020 The Humboldt and its Grate-Kiln System Operation on crude ore is a mixture of cherty specular hematite and magnetite, with minor amounts of martite and sericite. Mineralization varies from coarse to extremely fine grained. The overburden varies from zero to 50 ft. The ore body is approximately 1300 ft. long and varies in thickness from 250-400′
