CHARACTERIZATION OF WASTE ROCK FROM THE PHOSPHATE MINING FIELD OF BLED EL HADBA, ALGERIA IN AN ENVIRONMENTAL CONTEXT

In the world demand and consumption of raw materials minerals is sharply increasing, which has encouraged countries around to intensify mining different ores such as phosphate. Algeria, while phosphates are one country's most important natural resources; they ranked third in terms proven reserves with 2,200,000 tones, this ore low. The Bled El Hadba deposit promising Djebel Onk’s deposits 841 million tons starts 2020. exploited by open pit method, therefore a large quantity waste rock will be evacuated appropriate surfaces called dumps, consequently induce an increasingly serious destruction eco-environment. Intelligent use solid mine compensate for resource scarcity protect environment appears necessity. main purpose our research work involves characterization environmental management sand rocks from phosphate deposit. context, we studied series runs: Particle size analysis, Cleanliness equivalent sand, chemical analysis. results obtained encouraging glass building industry.
