Copper Concentrate - Vale

Particle size: The 80% passing size of fresh Copper Concentrate is expected to be 30µm based on pilot plant results (ranging from 15 to 50 µm). The Copper Concentrate is expected to age and oxidize during storage thus forming agglomerates and lumps. Solubility in water: Insoluble . Appearance in color: Odorless, grayish, slurry or moist powder

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%.
