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 metals and radioactive elements. 4 The mining and beneficiation process results in the majority of these hazardous elements being lost either to waste disposal or to the environment, mainly soil, water, atmosphere and human food chain.
For each ton of produced phosphate there is a similar ton of PMS produced, thus causing a serious problem regarding waste disposal . Wastes associated with phosphate mining and beneficiation activities are composed of both solid and liquid wastes.
In recent years Lake Mariut was subjected to severe pollution. The phosphate content of this Lake was exceedingly higher than that of the other Egyptian Lakes. The distribution of phosphates in Lake Expand
It receives 10 00015 000 m 3 day 1 of domestic sewage from Alexandria. The present study deals mainly with the influence of sewage pollution on the levels of nutrients in this eutrophicated basin. The lower average values of surface salinity reflect the effect of domestic sewage.
The beneficiation of phosphate ores containing carbonate gangue by conventional techniques such as physical separation methods or flotation is very difficult due to the similarities in physico ...
The mineral industry of Africa is the largest mineral industries in the world Africa is the second , Steel: 2% of the world, divided as South Africa 54%; Egypt 32%; Libya 7%; , Although there have been many problems with titanium mining in Africa, , The P2O5 content of African phosphate rock production is expected to....
