Cooling Vessel for Metal Recovery from Smelting or Melting Waste Products

Abstract

A cooling vessel for metal recovery from waste products including a first open end, a second closed end, and a sidewall extending between the first open end and the second closed end. The vessel has a longitudinal central axis extending from the first open end to the second closed end. In a plane including the longitudinal axis and extending from the first open end to the second closed end, opposing interior surfaces of the vessel are at an angle of 30°-50° to one another. The thickness of the sidewall adjacent the second closed end is greater than the thickness of the sidewall at the first open end. A diameter of the inner surface of the vessel along a first major axis may be greater than a diameter of the inner surface of the vessel along a second minor axis such that a cross-section of the vessel is oval.
