The use of steel grinding media can cause problems in the subsequent flotation processes that are used to separate the various minerals in an ore, because the iron from the grinding medium can affect the surface properties of the minerals and reduce the effectiveness of the separation.
Mining Industry Experience. GMSA is the leading supplier of the grinding media requirements for the Southern African mineral processing industries, (gold, platinum, base metals, cement and power generation) with exports to many African countries and more recently to Australia.
Milling and grinding media are the means used to crush or grind material in a ball mill or SAG mill and are designed for the grinding of bulk powder or granular materials into finer powder forms. The hardness of the powder or bulk material to grind determines the selection of the media material.

E. Allahkarami et al. 30 Such interactions occur whenever two or more sulphide minerals (or a sulphide mineral/grinding media) are in contact. The electrochemical reactivity is indicated by the rest potential of the sulphide mineral, .e. the higher i the rest potential, the nobler it is and the less active in thermodynamic sense.

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
Manufacturer of standard and custom grinding media for mills and disintegrators. Available as pierced screens. Pierced screens in screen hole and slot sizes from 0.06 mm to 6.5 mm and thicknesses from 0.2 mm to 3.0 mm are available.
Selection of grinding media is very important since the consumption of grinding media is one of the major operating costs in mineral processing industry, which can be up to 50% of the overall grinding expenditure (Aldrich, 2013). The consumption of grinding media can be caused by abrasion, impact, and corrosion wear mechanisms.
For mineral processing fine grinding applications, FL provides a range of ceramic grinding media's to best suit each sites specific requirements. Depending on your preferred selection parameters, Ludowici has a proven performing grinding media to suit.
60-75 % of the mill free volume is filled with grinding media (beads) that is typically 1-6 mm ceramics, with a density of about 4 g/cm3. The slurry is pumped into a grinding chamber via the feed inlet from the bottom of the grinding chamber.
