METHOD OF SEPARATING FLAT METAL ALLOY PARTICLES |
摘要 |
<p>A method is described for separating a mixture of flat metal alloy particles in which the particles of one alloy are generally smaller and less conductive than the particles of another alloy, e.g. a scrap mixture of aluminum-lithium alloy and other wrought aluminum alloys. In this method, the scrap mixture is thermally pretreated and then crushed into relatively flat particles, such that the aluminum-lithium alloy is fragmented into smaller particle sizes than the other wrought alloys. These particles are then physically separated based on differences in particle size, density and/or electric conductivity. For instance, the separation may be done by an eddy current separator or a dense media separator.</p> |
