The invention relates to a mineral benefication method for specularite, comprising recycling the iron ore concentrate in the specularite by first-stage coarse grinding, spiral chute sorting, low-intensity magnetic separating, high-intensity magnetic separating, second-stage ore-grinding, spiral chute sorting, high-intensity magnetic separating and reverse flotation separating process, or first-stage coarse grinding, low-intensity magnetic separating, spiral chute sorting, high-intensity magnetic separating, second-stage ore-grinding, spiral chute sorting, high-intensity magnetic separating and reverse flotation separating process. The method has the characteristics of simple process and structure, low investment cost, low production cost, economy and environment protection, and strong flexibility; when the mineral property changes, the iron minerals are sorted and recycled by properly regulating the method.
