ore pulp rougher flotation

  • Flotation - Mineral Processing & Metallurgy

    Jan 11, 2016 · As a rule, a pulp containing particles larger than 48 mesh (0.295 mm.) is not suitable for flotation, nor is it common for the ore to be ground to a product finer than that at which 95% will pass through a 200-mesh screen (0.074 mm.). The size of the finished material usually lies between these two limits.

  • Froth flotation - Wikipedia

    Various flotation reagents are added to a mixture of ore and water (called pulp) in a conditioning tank. The flow rate and tank size are designed to give the minerals enough time to be activated. The conditioner pulp [1] is fed to a bank of rougher cells which remove most of the desired minerals as a concentrate.
