chemical processing of phosphate ores. The key to understanding the association between environmental pollution and phosphate rocks lies in appreciating the mining and processing effect of phosphate ores. Phosphorus is normally produced by mining and beneficiation of Phosphate ores. 3 Mines produce large amounts of waste including toxic
The ores of manganese may be broadly classified as oxide, carbonate, silicate, and complex. Psilomelane and pyrolusite ores are the most common oxide ores and when these minerals are associated with quartz or silicate gangue they are readily concentrated. They become difficult and often impos
Screening is an important step for dry beneficiation of iron ore. Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated.
It is important to note that the grain size ofthe ore and associated gangue mineralscanalso have a dramatic,andsometimeseven limiting,effect onore beneficiation. Figure 11.1 illustrates two rich base-metalores, only one of which (11.1b) has been profitably extracted and processed. The McArthur

export purposes. Beneficiation of metallic ores, as well as non-metallic minerals, which is a primary requisite to the proper conser-vation of the mineral wealth, has been en-trusted to the National Metallurgical Labora-tory, in collaboration with the Indian Bureau of Mines. The latter with its field staff is to
Hence, to overcome these associated problems, lots of studies are required to utilize the low-grade iron ores, fines and slimes. Different Methods of Iron Ore Beneficiation A typical flow sheet for iron ore beneficiation plant utilizing crushing, scrubbing, screening, classification and dewatering is shown in Fig. 1 .

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.
