July, 1951 - Lean Ores Plant Being Built by Mining Company
Construction of a pilot plant by Western-Knapp Engineering Co. of San Francisco, and stripping of land preparatory to mining by the Bacco Construction company, of Iron Mountain, is in full swing at the old Groveland mine location, four miles east of Randville on highway M-69, where the Hanna Coal and Ore company's experimental plant for processing lowgrade iron is expected to be in operation by late fall. Concrete footings have been completed and upright construction has been started on the plant which, when completed, will be 113 feet long, 56 feet wide and 80 feet high. J. B. Richardson is superintendent of the job for Western-K n a p p, which has a branch office at Hibbing, Minn.
DOING OTHER WORK
The Western-Knapp company, specialists in construction of taconite plants, have other mining construction in progress throughout the nation. J. L. Prewett construction manager of the Eastern and North Central division of the company is here for several days inspecting the work here. Thirty-one men are employed on the pilot plant construction. According to Superintendent Richardson, the job is scheduled to be completed bv late October. Meanwhile, the Bacco Construction company, Iron Mountain, which has the contract for mining the ore to be used in the experiment, has a crew of 18 men and heavy equipment stripping the land and building roads. According to Joseph Rigom, president of the Bacco company, the contract calls for drilling, blasting and stock-piling 25,000 tons of low grade ore This supply, it is believed, will be sufficient to determine whether taconite can be produccd for commercial utilization.
ORE IS STOCKPILED ORE IS STOCKPILED
Rigom expects the 25,000 tons of ore will be stockpiled and ready for use in several months, or before the plant is ready for operation Superintendent Richardson said the pilot plant will have nine separate floors, on a staggered basis. There will be a difference of as little as one foot between the levels of some of the floors. The plant, he said, will have approxiamtely 100 pieces of processing equipment when the building is completed Western- Knapp also will install all the equipment. In April, when the Hanna company announced plans for the pilot plant at Randville. S. E. Quayle, of Iron River, superintendent of the Hanna operations in Michigan emphasized that the operation is purely experimental. The result of the experiment at Randville, he said, \vill determine whether production of taconite can be continued there on a commercial basis.
LEASED 2,560 ACRES
Before final plans for the Randville experimental plant were completed, the Hanna company obtained options for the lease of approximately 2,560 acres of land in the old Groveland mine area, The process of benftciation of low-grade ore consists principally of a series of grinding and washing operations by which iron ore is reduced to a fine powder, and the iron content segregated, by further washing and screening, and prepared for shipping to furnaces. The pilot plant at Randville will be the first of its kind in the Upper Peninsula.
