Abstract

The invention discloses a treatment method for sintering machine head dust recycled by the iron and steel enterprise. The machine head dust is wetted by water, the dry base weight ranges from 15% to 35%, and the water weight ranges from 65% to 85%; pulp mixing is conducted in a pulp mixing barrel, mixed pulp is subjected to gravity sorting in a reselection device, and iron middlings and primary enriched products of nonferrous metals and noble metals are obtained; the iron middlings are subjected to low intensity magnetic separation and then enriched; after low intensity magnetic separation and enrichment are sequentially conducted, iron concentrates containing 52%-58% of iron are obtained; and the primary enriched products of the nonferrous metals and the noble metals need to be subjected to treatment of the closed loop flotation process, circulation liquid in the sorting process serves as a raw material for producing potassium chloride for producing a potassium chloride product for the industry. The treatment method overcomes the defects in the prior art, and on the basis that the physical character of the material is sufficiently studied and judged, the treatment method for the sintering machine head dust recycled by the iron and steel enterprise is provided through the innovative reselection and flotation chemical engineering new technology method, wherein by means of the method, the low-content ferrous metals, noble metals and alkali metal resources in the sintering machine head dust can be recycled.

Description
