Mineralogical characterization and comparative study of two processing methods of iron ore from the Anini deposit (NE Algeria)

Abstract

The objective of this article is to study the possibilities of enrichment of the iron ore from Jebel Anini and to develop these mineral resources in order to use them in the metallurgical complex of Annaba. Representative samples were taken from Anini iron mine located in the northwest of the Wilaya of Setif. After sampling, mineralogical, chemical and size particles’ characterization was carried out. However, the analyzes performed by (XRD, SEM and FX) show that the ore is iron type hematite clay and siliceous gangue. The average contents of Fe2O3, SiO2 and Al2O3 are respectively 55%, 26.20% and 12%. The data collected after several preliminary tests of enrichment by washing (wet sieving) of the ore reveal significant results in iron content is 62% Fe2O3, 2 to 3% of quartz and 2 to 3% of clay. The tests conducted by wet magnetic separation show, on the one hand, remarkable results in iron content of 65.11% against 2.46% SiO2 and1.73% Al2O3 and , on the other hand, that the enriched product meets the standards required by metallurgy, releases from processes can be used as an addition in the preparation of cement.

Characterization and processing of low-grade iron ore from the Khanguet mine by electrostatic separation

“…Research studies on the structural and stratigraphic plan of the Djebel Djebissa area were carried out by Kowalski 1995 [1]. Other research studies on the characterization and processing of poor iron ores in Algeria are carried out by Idres [2][3][4] and by Chaabia [5].…”
