The copper industry chain encompasses the entire lifecycle of copper, including upstream mining and beneficiation of copper ore, midstream smelting of copper (from mined ore and recycled copper scrap), processing into copper products, application in end-use industries, and recycling of scrap copper for reprocessing.
• Mining Stage: Copper mining is carried out through open-pit mining, underground mining, and leaching methods.
• Concentration Stage: Copper ore undergoes flotation beneficiation to produce copper concentrate with relatively low copper content.
• Smelting Stage: Copper concentrate and scrap copper are refined through pyrometallurgy or hydrometallurgy to produce refined copper, which serves as raw material for downstream industries.
• Processing Stage: Refined copper is further processed into various products, including copper rods, tubes, plates, wires, ingots, strips, and foils.
• End-Use Stage: These products are widely applied in power electronics, construction, and transportation industries.
Upstream — Copper Ore to Copper Concentrate
Copper ore is diverse and can be classified into several geological-industrial types, including:
1. Porphyry Copper
2. Sandstone-Shale Copper
3. Copper-Nickel Sulfide
4. Pyrite-Type Copper
5. Copper-Uranium-Gold
6. Native Copper
7. Vein-Type Copper
8. Carbonatite Copper
9. Skarn Copper
The upstream copper mining sector is highly concentrated, and the gross profit margin in mining and beneficiation is significantly higher than in other stages of the supply chain.
Profit Sources in the Copper Industry Chain:
• Mining Sector: Revenue from copper concentrate (after deducting costs) and by-products (sulfuric acid, gold, silver, etc.).
• Smelting Sector: Revenue from refining fees and price spreads between contract and spot prices.
• Processing Sector: Revenue from processing fees, which depend on the value-added nature of processed products.
The upstream sector’s profitability is primarily determined by metal prices, processing fees, and mining costs. Due to the scarcity of copper resources, the upstream segment represents the highest value share in the copper industry chain.
Midstream — Smelting of Copper Concentrate and Scrap Copper
Copper smelting involves extracting metal from ore using methods such as roasting, smelting, electrolysis, and chemical processing. The primary objective is to reduce impurities or enhance specific components to produce the desired copper metal.
• Pyrometallurgy: Suitable for copper sulfide concentrates (mainly chalcopyrite concentrates).
• Hydrometallurgy: Suitable for oxidized copper concentrates.
Downstream — Refined Copper Consumption
Refined copper is widely used in industries such as power, electronics, machinery manufacturing, and construction.
• Copper and its alloys are the third most consumed metals worldwide, after steel and aluminum.
• In the electrical industry, copper is the most extensively used metal, found in wires, cables, and generator coils.
• In defense and aerospace, copper is used in ammunition, firearms, and heat exchangers for aircraft and ships.
• Copper is also utilized in bearings, pistons, switches, valves, high-pressure steam equipment, and various thermal and cooling systems.
• Additionally, civil equipment and heat exchange technologies heavily rely on copper and copper alloys.
This integrated structure illustrates the copper industry’s strategic importance and widespread applications across multiple sectors.
