Abstract
Combination method for the gasification of coal and the reduction of metal ores involving hydrogenation gasification of coal to produce hydrocarbons and a coke component. The coke is subjected to steam gasification and the gas therefrom used to reduce ores. Spent gas from the reduction is treated to convert CO in the gas to H.sub.2 and CO.sub.2. The CO.sub.2 is scrubbed out and the H.sub.2 is sent to the hydrogenation gasification to hydrogenate the coal.
