Yunnan Copper Co., Ltd. (000878.SZ): How It Works

• Primary product: copper cathode production from smelting and electrolytic refining-sold domestically and exported to downstream fabricators and traders.
• By-product recovery: extraction and sale of gold, silver, and sulfuric acid produced during hydrometallurgical and smelting processes.
• Precious/rare metals: recovery and sale of platinum-group elements and rare elements (platinum, palladium, selenium, tellurium, rhenium) recovered from anode slimes and flue dust.
• Recycling: purchase and processing of copper scrap and other non-ferrous scrap to produce refined metal for sale (reduces feed costs, diversifies feedstock).
• Trading & logistics: import/export of concentrates, cathodes, and chemical products to capture margin opportunities and balance raw-material supply.
• Strategic investments: equity stakes in mining companies and joint ventures to secure long-term concentrate supply (e.g., planned acquisition of 40% of Liangshan Mining Co., Ltd.).

• Feed sourcing: purchase of copper concentrates from domestic mines and imports; recycled scrap inputs; proprietary mine output from invested assets.
• Processing steps: smelting → converting → electrorefining; recovery circuits for precious metals and sulfuric acid production from SO2 capture.
• Product mix pricing: copper cathode prices follow LME benchmarks with domestic premiums; by-product revenues indexed to precious metal quotations and sulfuric acid contract prices.
• Cost structure: energy (coal/electricity/gas), anode/cathode processing costs, reagent consumption, labor, environmental compliance and emissions control costs.
• Revenue diversification: trading and recycling margins, and equity income from invested mining assets buffer volatile copper cycles.

• Copper cathode production (tonnes/year) - drives core revenue.
• Average realized copper price (RMB/kg or USD/tonne) - determines topline sensitivity to market.
• By-product sales (RMB mln) - diversifies margins and improves cash flow.
• Production costs (cash cost per tonne of cathode) - energy, smelting/refining, and raw-material costs.
• Utilization rates of smelters and refineries (%) - impacts fixed-cost absorption and unit economics.

• Resource acquisitions and joint ventures (e.g., the planned 40% acquisition of Liangshan Mining Co., Ltd.) are intended to secure concentrate supply and improve margins through upstream integration.
• Expansion of recycling capacity to increase feed flexibility and reduce exposure to concentrate price volatility.
• Optimization of recovery rates for precious and rare metals to lift by-product revenue per tonne of copper processed.
