摘要： A method and apparatus for step-by-step retrieving valuable metals from waste printed circuit board particles. Many kinds of metals, most existing in form of elementary substance or alloy, are contained in the waste printed circuit boards. Molten metals are separated selectively by supergravity separation at different temperatures to achieve the step-by-step recovery. Tin-based alloys, lead-based alloy, zinc aluminum alloy, crude copper and precious-metal-enriched residues with different metal contents are separated out and collected on the condition of different temperatures (T=200˜300° C., 330˜430° C., 700˜900° C., 1100˜1300° C.) and controlling the gravity coefficient (G=50˜1000) and separation time (t=2˜20 min) etc. Different metals or alloys can be separated quickly and efficiently and the residue concentration of precious metals can be obtained. The process is simple and low cost to provide an efficient way to recovery the enrichment of valuable metals from electronic wastes.

摘要： Systems and methods for treating a fluid with a body are disclosed. Various aspects involve treating a fluid with a porous body. In select embodiments, a body comprises ash particles, and the ash particles used to form the body may be selected based on their providing one or more desired properties for a given treatment. Various bodies provide for the reaction and/or removal of a substance in a fluid, often using a porous body comprised of ash particles. Computer-operable methods for matching a source material to an application are disclosed. Certain aspects feature a porous body comprised of ash particles, the ash particles have a particle size distribution and interparticle connectivity that creates a plurality of pores having a pore size distribution and pore connectivity, and the pore size distribution and pore connectivity are such that a first fluid may substantially penetrate the pores.

摘要： A quiescent melt handling system includes a melting furnace and a holding furnace communicating with the melting furnace for holding a molten metal melt. The holding furnace has a relatively large surface area and a relatively shallow depth, having a width to depth ratio in the range of 4-100 to 1. Also provided is structure in the holding furnace for separating inclusions from the melt in the holding furnace. A mold communicates with the holding furnace. A counter gravity casting system, which might comprise a vacuum assisted casting system, draws the melt into the mold.
