What’s the Copper Flotation Process in the Copper Mining Process?
China’s Growing Demand for Copper Ore
China consumes nearly 14 million tons of copper annually, accounting for 60–70% of global consumption—more than all other countries combined. With demand still expanding, domestic output cannot meet requirements, making copper ore imports essential for China’s industrial and economic growth.
According to customs data, from January to October 2021, China imported 19.165 million tons of copper ore and concentrate, a year-on-year increase of 6.3%. This highlights the country’s reliance on overseas copper resources.
Classification of Imported Copper Ore
Copper ores imported into China are generally classified into two categories:
- Copper ore – raw ore with naturally lower copper content
- Copper concentrate – processed material with higher copper content, suitable for smelting
Both forms are critical to meeting domestic demand for copper in industries such as electrical engineering, construction, machinery, medicine, and national defense.
Copper Processing Expertise at Dasen Mining
As imports continue to rise, efficient and professional copper ore processing becomes increasingly important. Dasen Mining provides complete beneficiation solutions tailored to both sulfide copper ores and oxide copper ores.
| Name | Definition |
| Copper ore | This type of copper ore refers to the sand-like copper ore mined from copper ore and beneficiated into high copper quality but generally unable to meet the concentrated standard. |
| Copper concentrate | YS/T308-2007, the copper concentrate industry standard, defines copper concentrate as a copper ore that has a copper content (mass fraction) greater than 13% obtained by flotation of copper-bearing ore. |
The Copper Flotation Process
Flotation is one of the most widely used beneficiation methods. The typical process includes:
- Crushing and screening – preparing the raw ore
- Stage grinding and flotation – separating valuable minerals from waste material
- Concentration and dehydration – refining the output
- Copper concentrate recovery – final product ready for smelting
This process maximizes copper recovery while maintaining cost efficiency.
