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 200-300 deg.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. |
