Metal Value Recovery from Metal Hydroxide Sludges

摘要

A two-year study investigating the potential for metal value recovery from metal hydroxide sludges has been completed. The objectives of the study were to: Develop a flowsheet to separate and recover metal values from metal finishing hydroxide sludge materials and operate on a laboratory scale (Phase I), Develop a test assembly of unit operations to accomplish the separation of metal values on a pilot scale of 75-100 pounds of sludge per day, Verify that the pilot scale unit operations accomplish appropriate separations, and Delineate potential operational problems.
