Refined nickel metal (Class 1); Primary production (pyro- and/or hydrometallurgy) to refinery gate; Production mix, CN

Upstream primary nickel supply chain aggregated to refined/electrolytic (Class 1) nickel at refinery gate, consistent with literature covering mine-to-refinery-gate nickel production routes and China-focused mainstream electrolytic nickel chains. Includes mining/beneficiation and downstream pyro- and/or hydrometallurgical processing and refining; co-product handling/allocation is route-dependent and not further specified in the flow context.
