The Band-e Narges deposit is located about 70 km northeast of the city of Badrud, northern Isfahan province. Band-E Narges ore deposit is mining for magnetite. To release valuable minerals, crushing and grinding implemented for separation ore from the gangue. Magnetic separation and flotation methods for upgrading magnetite iron ore were carried out in different experimental conditions with varied parameters. The particle size of the initial content was 74 microns for flotation, and 150 microns for magnetic separation. The initial samples, with the iron grade of 43.4% and sulfur of 1.9%, are individually subjected to upgrading by floatation and magnetic separation during which the affecting parameters for each method were optimized. The improvement in the optimal condition for magnetic separation culminated in 60.85% for the iron grade, 85.21% iron for recovery and 1.08% for sulfur content. The upgrading by floatation in the optimal mode produced 60.02% iron grade, 80.41% iron recovery and 0.95% sulfur content. To determine the best method for the pre-concentration stage of ore, the content gained from each technique passed reclining for grad improvement. The final content obtained from the magnetic separation of was undergone the floatation test yielded to a content with 64.3% iron grade, 77.15% iron recovery and 0.7% sulfur content. The use of magnetic separation as a pre-concentration stage for floatation method is proposed as an economical method for improving the grade of the iron and reduce the sulfur content and to avoid the high cost of grinding, which is costly part of processing procedures.

El yacimiento de hierro Band-e Narges se ubica a 70 kilómetros al noroeste de la ciudad de Bad Rud, en la norteña provincia de Isfahan, Irán. En este yacimiento se extrae magnetita. Para la extracción de minerales valiosos, se utiliza la separación por molienda y triturado desde la ganga. Se utilizaron los métodos de separación magnética y flotación con diferentes parámetros para la recuperación de la magnetita. El tamaño de la partícula inicial fue de 74 micrones en flotación y de 150 micrones en la separación magnética. Las muestras iniciales, con un 43.4 % de hierro y 1.9 % de súlfuro, fueron sujetas individualmente al mejoramiento por flotación y separación magnética, proceso donde se optimizaron los parámetros afectados por cada método. El mejoramiento por la separación magnetica registró un 60.85 % de hierro, mientras que por recuperación fue 85.21 % de hierro y 1.08 % de contenido sulfúrico. El mejoramiento por flotación en condiciones óptimas produjo un 60.02 % de hierro, con un 80.41 % de hierro recuperado y un 0.95 % de contenido sulfúrico. Para determinar el mejor método en la etapa de preconcentración de la mena, la ganancia de cada técnica estuvo reclinada para mejorar el contenido. El contenido final obtenido de la separación magnética se sometió a la prueba de flotación con un 64,3 % de hierro, con el 77.15 % de recuperación de hierro, y un 0.7 % de contenido sulfúrico. El uso de la separación magnética como una etapa de pre-concentración para el método de flotación se propone como un medio económico para mejorar el grado del hierro y reducir el contenido sulfúrico además de evitar el alto costo de la molienda, que es la parte más costosa de los procedimientos.
