China’s renewable energy development, including wind power, solar energy, energy storage, new energy vehicle, and lithium battery, kept expanding in recent years. The copper demand applied in these fields becomes critical. Also, the quality requirement for copper material becomes higher.

According to a copper industry company in Qinghai, China, its annual copper cathode production increased from 100,000 tons to 150,000 tons, and the daily output was 350 tons.

Apart from copper applied in renewable energy, the demand for copper applied in electric power, construction, and household appliances also went up.
