phase Leaching (extraction) If a fluid is being used to extract a solute from a solid. Crystallization Solute components soluble in a solution can be removed from the solution by adjusting the conditions such as temperature or concentration. Adsorption One or more components of a liquid or gas stream are absorbed on the surface or in the pores of a solid adsorbent. Membrane Processing The relatively thin‚ solid membrane controls the rate of movement of molecules between two phases. Physical-Chemical

Ely Mine EVSP 594 July 20‚ 2014 Phyllis Langone Ph. D. Ely Mine Executive Summary The Ely Copper Mine was mined from 1821 to 1920 sporadically for copper and during this time it added trace elements and acid runoff to the streams and river around the mine. The mine sat idle for almost twenty years when in 1942 the mine was reopened during the war because metals like copper were needed (USGS United States Geological Survey‚ 2007). The Ely Copper Mine in Vershire‚ Vermont has throughout the
