  • Process for recovering perrous values from municipal solid waste
    Patent number: 5890663
    Abstract: Dry municipal solid waste material is subjected to a two-step magnetic separation process to recover ferrous values therefrom. The process includes passing the raw solid waste material through a shredder to reduce the waste to particles at a size of 3 inches or less, passing the particles through a series of two magnetic fields, recovering ferrous-containing fractions from each passage, combining the two ferrous-containing fractions and subjecting them to air classification in a cyclone separator to recover a clean particulate ferrous product, and a waste byproduct and recycling the waste byproduct to pass again through one or both of the two magnetic fields.
