Abstract
Provided is a sorting method for valuable resources, including a thermal treatment step of thermally treating a target containing valuable resources, to melt aluminum and separate a melt, a pulverizing step of pulverizing a thermally treated product remaining after the melt is separated, to obtain a pulverized product, a magnetic sorting step of sorting the valuable resources from the pulverized product by a magnetic force, and a wind force sorting step of sorting one valuable resource from another valuable resource in the valuable resources by a wind force.
Claims7
A sorting method for valuable resources, the sorting method comprising:
- thermally treating a target containing valuable resources, to melt aluminum and separate a melt;
- pulverizing a thermally treated product remaining after the melt is separated, to obtain a pulverized product;
- sorting the valuable resources from the pulverized product by a magnetic force;
- and
- sorting the valuable resources sorted by the magnetic force into one valuable resource and another valuable resource in the valuable resources by a wind force,
- further comprising after the pulverizing,
- sieving the pulverized product, to classify the pulverized product into an oversize product and an undersize product,
- wherein after the classifying, the oversize product is subjected to the sorting by the magnetic force, and
- wherein in the classifying, sieving is performed with a sieve having a mesh size of 0.6 mm or greater but 2.4 mm or less.
