Primary Smelting & Refining of Nonferrous Metals

Primary Smelting & Refining of Nonferrous Metals

The Primary Smelting & Refining of Nonferrous Metals sector (SIC 3330) produces aluminum, copper, zinc, nickel, and precious metal ingots, cathodes, and alloys for automakers, aerospace and electronics OEMs, construction suppliers, battery makers, and renewable energy projects. Core services span ore and concentrate processing, anode/cathode casting, toll refining, and recycling of scrap and industrial residues. Operators face volatile metal and power prices, tightening EPA emissions and tailings rules, carbon reporting requirements, permitting delays, and geopolitical supply shocks, alongside strict worker-safety obligations. In 2024-2025, investment is flowing to low-carbon smelting technologies, electrified furnaces, AI-driven process control, and traceable recycled feedstocks to capture green premiums, while demand is buoyed by EVs, grid expansion, and data center build-outs and tempered by high energy costs and selective capacity restarts.
