About slag, ash and residues; (not from the manufacture of iron or steel) containing metals, arsenic or their compounds

HS code 2620 covers a diverse range of slag, ash, and residues that contain metals, arsenic, or their compounds. These materials are generated from various industrial processes, excluding those related to the manufacture of iron or steel. This industry plays a crucial role in the broader economy, as it enables the recovery and recycling of valuable materials that would otherwise be considered waste. By extracting and repurposing these resources, the industry contributes to sustainable resource management and the circular economy.

Production process

The production techniques used in this industry typically involve a combination of physical and chemical processes. The initial step often involves the collection and sorting of the slag, ash, and residues based on their chemical composition and metal content. This is followed by various separation and concentration methods, such as gravity separation, magnetic separation, or leaching, to extract the desired metals and compounds. The refined materials are then further processed, depending on their intended use, which may include smelting, refining, or chemical treatment.

Production inputs

The main inputs required for this industry include the slag, ash, and residues generated from a wide range of industrial activities, such as non-ferrous metal production, waste incineration, and various chemical processes. Additionally, the industry relies on specialized equipment and machinery for the collection, sorting, and processing of these materials. Energy sources, such as electricity or fuel, are also necessary for the various stages of production.

Production outputs

The primary outputs of this industry are the recovered metals, metal compounds, and other valuable materials extracted from the slag, ash, and residues. These outputs can be used as feedstock for 2804 Hydrogen, rare gases and other non-metals, 2805 Alkali or alkaline-earth metals; rare-earth metals, scandium and yttrium, whether or not intermixed or interalloyed, 2811 Other inorganic acids and other inorganic oxygen compounds of non-metals, and other related industries. The industry also generates secondary products, such as slag or ash that can be used in construction materials or as soil amendments.
