Method for producing high-grade ferro-nickel directly

When high-grade ferro-nickel is produced by selectively reducing and refining nickel from nickel containing oxide ores and retaining iron in the slag in an electric furnace, it is not satisfactory to merely lower the proportion of reducing agents to the ore to be charged in the furnace, because not only the amount of nickel which goes into the slag increases and the yield of nickel decreases, but also the
