"This experimental study was conducted in three phases. The third phase results are summarized in this report. The first phase study objectives were to develop preliminary flowsheets for the separation and recovery of metal values from mixed metal sludge materials; to perform laboratory studies to test the applicability of the preliminary flowsheets; to develop a test assembly of unit operations capable of treating 75-100 pounds of sludge per day; and to conduct preliminary testwork in the test assembly to delineate conditions for successful operation and/or to note potential operational problems. The second phase objectives were: to investigate potential alternate unit operations identified in Phase I; to further test the assembly developed in Phase I; to develop long-term continuous test data for the unit operations; and to delineate potential process and materials handling problems. The results of the Phase I and Phase II studies are reported in EPA 600/ 2-85/128 "Metal Value Recovery from Metal Hydroxide Sludges," March 1985 (PB86 157294/AS)." |
