The Phosphate deposits in Egypt represent one of the most economic deposit with a yearly…..million ton production those highly production
are covered the local market and about…..% of its …….. to several countries among there India, and………….
The quality of the reserves is measured directly by its P2O5 %. The World wide percentage should be above …..% P2O5 , The Egyptian phosphate has ….% in average. This deposit are locality in the Eastern Desert at Kharga , Dakhla and Abu-Tartour platue and distributed at the Eastern Desert at the Red Sea in Hamarwien , Qusier , and around the Nile Valley at Sibaia and El Mahamid .
The study in this project is focus in estimation of ore reserve at Eastern Mahamid district-using computes facilitates, getting advantages of its fast accurate and easy way of calculation.
The principle of calculation we based upon the triangulation method where the sampling area is divided into a triangulation net with known X, Y and measured of P2O5 of ore at each location.
Two ways have implemented to conduct the calculations, the first is using Excel software to determining the lengths of each triangle in the net from the coordinates, and average thickness, and average assay of the ore, and thus estimate the average thickness and assay of the ore in the study area. The same variables (average thickness of the ore and average assay) have been determined using Kriging technique.
This study reviews the world production of the phosphate and addresses the main mining method of ore extraction using surface mining. Results of ore reserve estimation at Eastern Mahamid showed that the average thickness of the ore deposit …and average P2O5.
340 sampling points taken from the area under study at El Mahamid district, Eastern Desert of Egypt Were used to estimate the ore reserves of phosphate deposits and the average thickness and average P2O5 content. The study has focused on applying an approach supported with statistically steps that lead to an accurate and logic estimation.
The phosphate mining in Egypt represents one of the largest mining investments with annual production of 56 million tons. These highly production are covered the local market and about 80% of it exported to several countries, among them Ukraine and India.
The quality of the phosphate ores is mainly determined by it percentage of P2O5. The accepted grade in the industry is 22%. Fortunately, the Egyptian phosphate has 25% in average.
The use of computer facilities has become widely increased in different areas. Mining engineering in general and ore reserve evaluation in particular are among these applications.
This project aims to determine the phosphate ore reserves at El Mahamied area. Several factors have been taken into considerations during the calculations using Excel software, such as providing robust, accurate, and easy use tool that would assist the mining industry. The calculations have conducted based on the Triangular method, statistical analysis of the raw sampling data.
Giving X, Y, Z and one ore more variable, for a certain area and with sufficient samples, the software has the capability of determine the total area, volume, ore reserves, distribution of the variable under study and point estimation for any un-sampled point within the entire area. The results are introduced as tables, figures, contour maps, and three-dimensional representation of the variables.
On the other hand, the students have prepared a database for El Mahamied phosphate mine to be added to the "Mining Information System (MIS), a part of a Software developed in 2003 at Mining Engineering Department”. This infant project will help the mining authorizations, investors as well as the researchers to exchange a quality digital data with different formats (maps, attributes, figures, reports, etc.) and get rapid access to the information for all the Egyptian mines.
