Development of New Cost-Effective Methods for Removing Trace Contaminants in Recycled Metals

Cost-effective technologies for the in-melt removal and/or neutralization of trace contaminants in metals is critical for secondary feedstocks to achieve cost parity with primary feedstocks. This exploratory project will experimentally evaluate the addition of “scoping” elements in molten aluminum to neutralize trace contaminants that would otherwise constrain the recycling of aluminum.
