particle size of copper concentrate

copper concentrate particle size distribution

Particle Size Of Copper Concentrate. Copper concentrate is a flotation product with fine particle size. The copper concentrate, which is close to dry, and it is easy to be lost in the process of storage and transportation, however, it is not suitable for ocean transportation, so the copper concentrate is often kept about 10% moisture in the ...

Copper Concentrate - Vale

2013-5-20  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

Guidance on Classification of Copper Concentrates for MHB

Copper concentrates are mainly produced by flotation. The ore is crushed and milled to a particle size of less than 100 µm. This produces a mix of particles containing pure phases of primary or secondary copper sulfides. The ground ore is mixed with water and reagents, to form a slurry, where the copper sulfide mineral particles
