Based on the shape of the particles, all of the 1.0% molybdenite transferred to the tail is composed of liberated blade-shaped molybdenite particles. Molybdenite particles in this sample appear to have a size limitation, particles smaller than 10.0 μm, despite being liberated, are transferred into copper concentrate or molybdenite tailings.

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).
