Copper Concentrates - Cargo Handbook - the world's largest ...

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%.

Moisture effect on the combustion of a single copper ...

When a concentrate with high moisture content is charged, the particle size enlargement due to the agglomeration of concentrate particles causes an abrupt fall in the particle reaction rate. A mathematical model has been presented to study the combustion of a single copper concentrate particle with high moisture content.
