    • PURPOSE: To obtain the iron powder for a concrete reinforcing aggregate, a chemical body warmer, or the like, by refining the metallic iron content of a pig iron-contg. slag until the iron content gives ≥90%, and subjecting the refined metallic iron content to screening, particle size regulation, or the like, to gain the stabilization of properties.
      CONSTITUTION: The pig iron-contg. slag is subjected to crush and magnetic separation, required times, repeatedly, to be recovered by separation, and is refined until the metallic iron content gives ≥90% in total. The refined matter is subjected either to screening and grain size regulation or to pulverization and air classification. In this way, pulverized iron of each particle size having uniform and stable quality can be obtained.

    • PURPOSE: To recover efficiently useful metal contained in slag, by crushing crude concentrate obtd. from stainless slag to ore dress it by gravity to metal part and residue, and separating fine particle metal part by dressing said residue magnetically.
      CONSTITUTION: If stainless slag is received in one hole pan and cooled to about 200W300°C, it expands and breaks down. The slag is separated by sieve of about 25mm, metal is recovered from material thereon, crude concentrate of high metal content and slag are separated from material thereunder by gravity or dressing machine. The crude concentrate is supplied to crusher, crushed, supplied again to mineral jig, separated to metal part and residue to recover metal part. Further, the remaining fine particle metals are separated from residue by a magnetic dressing machine. In this way, the useful metal contained in stainless slag can be recovered and used efficiently.

    • 目的:通过粉碎粗品浓缩液,有效回收炉渣中有用的金属。 从不锈钢矿渣通过重力将其穿过金属部分和残渣,并通过将所述残留物磁性地包裹来分离细颗粒金属部分。 构成:如果不锈钢渣在一个平底锅中被接收并冷却到约200-300摄氏度,则会膨胀和分解。 炉渣由约25mm的筛子分离,从其上的材料回收金属,高重金属含量的粗精矿和矿渣通过重力或修整机与物料分离。 将粗浓缩物供给破碎机,粉碎,再次供给矿物夹具,分离成金属部分和残留物以回收金属部分。 此外,剩余的细粒金属通过磁力修整机与残渣分离。 以这种方式,可以回收和使用不锈钢渣中含有的有用金属并有效地使用。
