Abstract
An energy efficient, coal-based method and apparatus that are environmentally friendly which produce under pressure metallized/carbon product and molten metal directly from abundant coal or other carbonaceous material, and low cost fines (or ore concentrate) wherein the metal is devoid of gangue material and possesses the inherent advantage of retaining the heat for subsequent processing. This method and apparatus which are modular and highly integrated significantly reduce capital and operating costs; they also provide the capability selective placement of the reductant for the delivery of high levels of thermal energy input which leads to ease of desulflurization and high productivity. The technology herein disclosed is entirely closed and is applicable to various ores including ferrous and non-ferrous.
