In dense media separation a media is created with a density in between the density of the ore and gangue particles. When subjected to this media particles either float or sink depending on their density relative to the media. In this way the separation takes place purely on density differences and does not, in principle, relay on any other factors such as particle weight or shape. In practice

The Journal of The South African Institute of Mining and Metallurgy JULY 2001 165 Introduction There are six parallel conventional milling circuits at Palabora Mining Company. Each milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without

grinding media to ''real'' ore systems at an industrial level to improve metallurgical performance has not gained universal acceptance. Even when it does become the ''industry standard'', for example the PGM mining industry in South Africa, when events like the global financial crisis occur the status quo is challenged based on unit cost of the raw material as mining companies pursue cost

· In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix. The practical applications of this research are a reduction in

While most grinding in the mineral industry is achieved using devices containing a steel grinding medium, the IsaMill uses inert grinding media such as silica sand, waste smelter slag or ceramic balls. 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

· As the size reduction ratio increases, the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of 128:1 (Fig. 7d), a mm/ mm ball mix at a 13:87 ratio was found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.
