Title:
RECOVERING METHOD OF VALUABLE METALS CONTAINING COPPER FROM WASTE PRINTED CIRCUIT BOARD AND SYSTEM FOR RECOVERY OF VALUABLE METAL CONTAINING COPPER AND SEPARATION OF SLAG COMPONENT FROM WASTE PRINTED CIRCUIT BOARD
Document Type and Number:
Japanese Patent JP2000104126
Kind Code:
A
Abstract:
To provide a recovering method of valuable metals containing copper from a waste printed circuit board capable of suppressing running cost to a minimum without executing considerable plant investment and a system for the recovery of valuable metals containing copper and the separation of slag component.
The waste printed circuit board is pulverized and blown into a powder burner 10 of a melting refining furnace 30 heated to 1,300-1,600°C with combustion air, retained for about 0.5-6 sec to be combusted and to melt non-combustible components contained in the waste printed circuit board, and introduced into the melt refining furnace from the bottom of a combustion chamber to separate metals or mat/slag and to recover metals or the mat.
