“…Batch smelting tests on Mount, Montana, and Coquille, Oregon, chromite concentrates have been described by Wessel and Rasmussen (5). The practicability of using hogged fuel in electric smelting charges when smelting Pacific Northwest ores was pointed out by Rasmussen (6). Cremer's report oil nickel smelting investigations at the Northwest Electrodevelopment Laboratory was released in January 1954 (7).…”

A dry-top, arc-resistance, electric smelting technique for recovering strategic nmtals from off-grade ores is described. Advantages of using a bulky form of reductant such as hogged wood waste in the furnace charge are pointed out. Smelting test data on nickel ores, a siliceous manganese ore, off-grade chromite concentrates, a fine grained chromite ore, and aluminmn silicates are presented. The relationship between a theoretical smelting efficiency and slag-to-metal ratio is shown. The possibility of applying this drytop, arc-resistance, electric smelting technique to other ores is indicated.

“…After a discussion of constructional details in connection with air blast, the author draws the conclusion that, provided reliable air blast conditions exist and a straight run of the same briquet are used, the total cost of air blast practice remains less than those incurred by electric smelting. Rasmussen (208) described a cooperative research program on the production of ferronickel from nickel silicates that provides data for the planning of a production smelter in southwestern Oregon. It was found that the ratio of nickel to iron in the ore is high enough to produce alloy pig iron of about 15% nickel grade without recourse to selective reduction smelting.…”
