Abstract
Method and apparatus are described for the controlled cooling of processed oxidic ores in a shaft furnace in order to produce an improved product. Means are provided in the cooling section of the furnace chamber that enable the chamber to be divided into separate regions within each of which the admission of low temperature reducing gas can be regulated in order to more effectively control the distribution of reducing gas across the furnace.
