Abstract
We would like to thank our colleagues of Laboratory of Mineral Processing and Environment “LAVAMINE” Badji Mokhtar University Annaba, the laboratory of ENSMM Annaba for their assistance to complete the analysis tests and also, we are grateful for all the staff of the Mineral Processing Engineering Department of ITU- Istanbul, Turkey.
Highlights
The industry generates great quantities of tailings throughout the world, the mining industry, which produces a variety of rejections because of the intensification of mining activities and the increased need for raw materials
The chemical reagents used in the flotation tests are the sodium oleate which plays the role of the collector; alkyl hydroxamic acid is used as frother and collector agent to create hard and tenacious foam
By comparing the P2O5 contents determined in the different apatite recoveries, we found that the best recovery content value of 81.6% is produced at Aero 6493 concentration of 250 mg/l (Fig. 6)
Summary
The industry generates great quantities of tailings throughout the world, the mining industry, which produces a variety of rejections because of the intensification of mining activities and the increased need for raw materials. These residues must be managed in a rational and safe manner, even if neutralized, in order to protect the environment, preserve nature and human health. In Europe, a draft legislation governing the management of residues was first published by the European Commission in October 2000. The purpose of regulation No 596/2009/EC published in 2009 in
