Illinois Valley News, Thursday, March 11, 1940 ergency, but furnace processes proved so costly that efforts were abandoned after the war. The reduction by furnace, él ectric or otherwise, is practical only for ore that is from 48 per cent to 52 per cent chromite, met allurgists declare. Oregon chrom ite ores are of much lower grade. Schulein and his co-workers in the Oregon State college depart ment of chemical engineering, where he has been a special stu dent for almost a year, working on his process, now claim that pur er chromium than that produced from high-grade ore can be turned out electro-chemically from local low-grade ore. 'The furnace method requires ore of more than one-half inch mesh, which eliminates the Oregon beach sand. Schulein said. Some of the beach sand, he de clared, runs 4 per cent chromite. “By screening,” he said, “we got it up to 32 per cent.” In getting away from the fur- nace operation, Schulein said, he puts the chromite into a solution as chromates. First step is to grind the ore to ten mesh or smaller, or start with beach sand, The ore then is leached — that is, treated with chemicals which will dissolve it. The dissolved chromite then goes into a solution as chromate—a combination of chromite and oxy On the next day much people that were come to the feast, gen—and at the same time iron is precipitated out as iron salt. when they heard that Jesus was coming to Jerusalem, As a by-product, the iron salt Took branches of palm trees and went forth to meet him, and cried.

Schulein, ex-employe of the ( hromium Company of America, is a graduate of the University of V'isconsin. He lives at 3505 NE I’ancock street, Portland. He has b-?en working on his project in the Oregon State college laboratory at Corvallis for several months, with the backing of L. B. Haley, Hillsboro meat canner, and with the aid of Professor George Glee-, son and G. C. Ware of the college's chemical engineering department. Earl K. Nixon, director of the s'ate department of geology and mineral industries, took an early interest in Schulein’s experiments and provided ore samples and lab- < -atory assistance. “If he has perfected his proc- < ..s,” Nixon commented, “he has something that wil upset the vhole chromium industry.

The metallic chromium is melt ed down with pure iron to pro duce ferro-chromium, which has a wide variety of uses because of its hardness. Schulein said his product is without carbon, an additional ad vantage over the furnace product. “1 estimate that I can produce pure chromium from low-grade domestic ore at the cost of the lowest grade ferro-chrome,’’ said Schulein. “The United States im ports about one-half its chromium. With perfection of this new pro cess, the Pacific northwest could supply the entire domestic demand of this country. The American market demand for chromium is about 300 tons a year, Schulein said. The electro-chemical process requires about 40 killowat-hours of energy to produce a pound of chromium, Schulein said. Low- cost power from Bonneville will be an important factor in develop ing such an industry, he indicated. Schulein has set up the process es of his experiment on a labora tory basis for demonstration at the state college. Plans are being made for a re duction plant in Portland, he said.
