مصنع لتجهيز البوكسيت/new grinding technique for rock phosphate
Mechanical activation technique represents a unique process in which the mineral surface reactivity can be increased in addition to having new products. Phosphate is a one of the plant nutrients that can be produced from phosphate rock. However, direct usage of the phosphate rock has several limitations. In
Pat. No. 4,181,703 offers yet another technique for conducting wet grinding of the phosphate rock. According to this patent, salt water is used instead of fresh water for the grinding operation. Such a substitution is believed to solve the aforementioned problem of fresh water consumption, but it fails to reduce the total quantity of contaminated water produced by .
The effects of acid concentration, acid/rock ratio, and fineness of grinding on the interaction between Moroccan phosphate rock and sulphuric acid, in the preparation of superphosphate, have been studied. An organicsolvent technique has been used to follow the course and the rate of the chemical reactions.

· Energy consumption in thermal treatment of phosphate ores. The amount of energy for mining and physical beneficiation of phosphate ores to produce one ton of commercial rock phosphate (32% P 2 O 5) is approximately GJ/ton of rock phosphate (about GJ/ton P 2 O 5 ). However, if the rock is calcined, the total energy requirement is doubled ...
· Also, rock grinding requirements are lower because a satisfactory rate of reaction can be achieved from much coarser rock in the hemihydrate process. Disadvantages are ; risk of slower filtration, phosphate losses and risk of corrosion due to a higher temperature and higher acid concentration than in the other processes (BAT N° 4, 1995).

techniques. Physical synthesis methods include sedimentation processes, rotor speed mills, high energy ball mills and mixer mills. In general, phosphorus (P) nanoparticles are prepared by purifying rock phosphate and grinding them with a high energy ball mill or mixer mill smaller than 500 nm and altered properties. 2.
· 38 Mohamed Abuel Kasem Mohamed et al.: Upgrading of Phosphate Ore Wastes of ElNasr Mining Company, Egypt associated gangue minerals present in the mined rock [6]. The most common gangue minerals in phosphate ores are quartz, chert, clay, feldspar, mica, calcite, and dolomite [7]. In some cases, simple, inexpensive techniques are enough
· A phosphate ore from Abyad area in Jordan was crushed to minus 5 mm in a jaw being dried at 60 °C for 120 min, the sample was subjected to dry grinding in a ball phosphate ore mainly consists of fluorapatite, calcite and quartz minerals (seen in Fig. 2). Table 1 shows the results of chemical composition analysis.
· Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the lowgrade phosphate ore .
