Recuperación De Apatita De Relave Producidos en La Concentración Magnética De Hierro

Abstract: La apatita es el mineral de fosfato más común, además de ser un recurso no renovable es la única fuente económicamente viable de fósforo para los fertilizantes y productos químicos fosfatados. Chile en el año 2016 produjo 6.205 toneladas de recurso fosfórico y en el mismo año importó 230.738 toneladas. Esto hace necesario estudiar tecnología para concentrar los minerales de fosfato presentes en los relaves de hierro, promoviendo la diversificación productiva y disminuyendo los volúmenes de pasivos ambientales.… Show more

“…Considering that phosphorus recovery could be carried out from tailings [23,24] to ensure the supply of phosphorus for fertilizers, the purposes of this work were as follows: (a) to characterize and evaluate the performance of a new synthetic collector, Atrac-2600 (anion collector sold by AkzoNobel-Brazil), to float apatite from iron tailings, different from fatty acid collectors, and (b) to design a laboratory-scale flotation circuit to produce apatite concentrate of commercial interest from the iron tailings generated in the Minera del Pacífico Company, located in the Atacama Region-Chile.…”
