Abstract
This is provided a process for recovering metallic element including iron from a metallic iron-comprising derivative. The process comprises the steps of: (1) activating the metallic iron-comprising derivative comprising sponge iron with a gaseous processing agent comprising hydrogen sulphide and a carbonylating agent comprising carbon monoxide, (2) carbonylating the metallic iron-comprising derivative that has been activated to obtain a carbonyl, and (3) decomposing the carbonyl to obtain the metallic element.

A process for recovering metallic iron from sponge iron, comprising:
- carbonylating a metallic iron-comprising derivative material, which is derived from the sponge iron, with effect that iron carbonyl is obtained;
- and
- effecting decomposition of the iron carbonyl.
A process for recovering metallic iron from a metallic iron-comprising material includes at least 60 weight % iron, based on the total weight of the metallic iron-comprising material, comprising:
- carbonylating a metallic iron-comprising derivative material, which is derived from the metallic iron-comprising material, with effect that iron carbonyl is obtained;
- and
- effecting decomposition of the iron carbonyl.
A process for recovering a metallic element from a metallic element-comprising material, comprising:
- contacting the metallic element-comprising material with a gaseous processing agent, with effect that an activated metallic element-comprising material is obtained, wherein the gaseous processing agent includes gaseous hydrogen sulphide and a carbonylating agent;
- carbonylating a metallic element-comprising derivative material, which is derived from the activated metallic element-comprising material, with effect that a carbonyl, of the metallic element, is obtained;
- and
- effecting decomposition of the carbonyl of the metallic element.
A process for recovering a metallic element from a metallic element-comprising material, comprising:
- emplacing the metallic element comprising material within a contacting zone;
- evacuating the contacting zone;
- after the evacuating, contacting the metallic element-comprising material with a gaseous processing agent within the contacting zone, with effect that an activated metallic element-comprising material is obtained;
- carbonylating a metallic element-comprising derivative material, which is derived from the activated metallic element-comprising material, with effect that a carbonyl, of the metallic element, is obtained;
- and
- effecting decomposition of the carbonyl of the metallic element.
