7 2.5 Grinding is the stage of size reduction (wet or dry) where the liberation size for individual minerals can be reached. Size reduction by crushing has a size limitation for the final products.
Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.
Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. These ball mills are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA/RNA recovery. Planetary Ball Mills meet and exceed all requirements for fast and reproducible grinding to analytical fineness.
The metallisation degree of reduced ilmenite concentrate increased as the time of wet grinding increased. Under the constant reduction conditions, the degree of metallisation improved from 68.58% to 87.32% while the FeO content decreased from 10.62 to 5.28% as …
In a method for recovering a copper sulfide concentrate by froth flotation from an ore containing an iron sulfide, wet grinding of the ore with grinding media made of high chromium cast iron alloy having a chromium content of from 10 to 35 % by weight is combined with an addition of hydrogen peroxide to the conditioned mineral pulp before or during flotation in order to improve concentrate ...
Wet grinding can reduce the particle size and increase the specific surface area of ilmenite concentrate. The average grain size can decrease from 50.13 μm to 30.24 μm after 60 min. The specific surface area of the material can increase from 0.23 m 2 /g to 0.49 m 2 /g as the wet grinding time increased.
