Abstract (English):	By means the chemical and mineralogical characterization of the heavy, magnetic and electromagnetic fractions of the black sands from the placer deposit of Mejías was succeeded to make a metallurgical load in order to obtain an useful slag as matrix flux for the automatic welding (SAW) and a ferroalloy as alloying load for several electric arc welding consumables. The obtained presents an oxide's composition that guarantees the metallurgical and technological properties and of the desired slag of flux. The complex alloy obtained by carbotermic reduction in electric arc furnace with graphite crucible presents relatively high contents of Mo (2,87%), Nb (> 1,80%), V (> 1,20%) among other metallic element of high metallurgic value for the manual and automatic welding (SMAW and SAW).

Abstract (Spanish):	A partir de la caracterización química y mineralógica de las fracciones pesadas, magnéticas y electromagnéticas de las arenas negras del placer de Mejías, se logró confeccionar una carga metalúrgica para obtener una escoria útil como matriz de fundentes para la soldadura automática (SAW) y una ferroaleación como carga aleante para diferentes consumibles de soldadura por arco eléctrico. La escoria obtenida presenta una composición de óxidos que garantiza las propiedades metalúrgicas y tecnológicas de la matriz de fundente deseado. La aleación compleja lograda por reducción carbotérmica en horno de arco eléctrico con crisol de grafito presenta relativamente altos contenidos de Mo (2,87 %), Nb(> 1,80 %), V(>1,20 %), entre otros elementos metálicos de alto valor metalúrgico para la soldadura manual (SMAW) y automática (SAW).
