Problems solved by technology

[0002] Existing methods of processing metal feedstocks into ferrous and non-ferrous metal products are notoriously inefficient, polluting and very costly financially, operationally and maintenanceally
Second, there are issues involving health hazards that affect workers in these fields due to exposure to extremely high temperatures and inhalation of harmful dust and foul gases

Embodiment Construction

[0021] Before the present invention is described in detail, it is to be understood that the invention is not limited to the details or arrangement of parts illustrated in the drawings, for the invention may operate with other embodiments. It is also to be understood that the terminology contained herein is for the purpose of description and not limitation.

[0022] Referring to Fig. 1, numeral 10 denotes a reactor in which iron ore is treated with coal to produce an iron / carbon product; this treatment of ore is hereinafter referred to as "carbon treatment". Reference numeral 11 denotes a furnace / homogenizer in which the iron / carbon product is melted with an oxidizing agent to produce molten iron and slag, hereinafter referred to as "oxidative melting". A standpipe indicated at 12 is connected to the furnace / homogenizer 11. Metal containers, indicated at 13, are used to receive molten metal and slag. Referring to Figure 4, a storage system containing raw materials is indicate...

Abstract

An energy efficient, coal-based method and apparatus, a reactor (10) 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 molten metal is devoid of gangue material and possesses the inherent advantage of retaining the sensible heat for subsequent processing.

Description

technical field [0001] This invention relates to the production of metals from metal oxides using carbonaceous materials and is subject to the disclosure contained in pending application No. 09 / 241,649 filed by the applicant on February 1, 1999 and assigned to Technical Unit 1742 content promotion. In particular, the invention also includes further developments of the subject matter disclosed in this referenced application, especially with regard to the transport of raw materials, the heating of raw materials and the reaction of these raw materials with one another. Additional developments in melting and slagging operations are also disclosed herein in order to provide an efficient integrated process and equipment to perform these operations which are environmentally sound and cost competitive in the production of metals. Background technique [0002] It is well known that existing methods of processing metal feedstocks into ferrous and non-ferrous metal products are financ...
