Abstract: Provided herein are processes for the synthesis of hydrogen gas (H 2 ) in a reactor under mild hydrothermal conditions, at a temperature between 120° C and 240° C and a pressure below 70 bar. The processes comprise contacting metallic iron (Fe 0 ) or a Fe(ll) containing compound with an aqueous composition comprising carbonate ions; and letting the metallic iron or Fe(ll) containing compound react with water, thereby obtaining magnetite and hydrogen gas.

Abstract: Process for recovering non-ferrous metals from industrial mineral residues Process for recovering a non-ferrous metal from a first solid residue (11) comprising iron. The first solid residue (11) is mixed (10) with a second solid residue (12) comprising sulphur thereby obtaining a particulate mixture (13). The particulate mixture is subjected to a roasting (20) step at a temperature of at least 650°C to obtain a roasted mixture (21), and the roasted mixture is subjected to leaching (30) in a liquid (31) at a pH of at least 5.5 to obtain a solution (41) enriched with the non-ferrous metal.

Abstract: A method of making a composite compact or briquette comprises mixing a first particulate material with at most 15% by weight of a powder coating material to obtain a mixture, and compacting the mixture into a compact. Either the first particulate material, the powder coating material, or both are advantageously waste materials. The first particulate material has a metal content of at least 50% by weight. The compact can be cured at temperatures between 50°C and 300°C to obtain the composite briquette. The composite briquette comprises a binding phase formed of the cured waste powder coating material, and a dispersed phase formed of the first particulate. The composite briquettes can be used as a secondary ore material.
