DETAILED
OVERVIEW:
In this
experiment one 20 liter polyethylene tank holds a copper sulfate
solution at a level of five grams of copper per liter, and a second
20 liter tank holds a solution of LIX in kerosine. LIX is a mixed
oxime that reversibly binds copper. Each tank feeds a variable
speed roller pump, and the pump outputs are combined and sent to a
small glass mixer vessel equipped with a variable speed stirrer.
The mixer effluent passes to a settler which separates the aqueous
and organic phases. The aqueous phase is analyzed for copper by a
Spectronic 20 spectrophotometer. The basic data for a run consists of the copper and LIX feed rates, the stirrer speed, and the copper level and the feed and aqueous effluent solutions. The data can be processed to determine the effect of feed rates and stirrer speed on the copper transfer rates. Depending on stirrer speed, copper removal can vary from 0 to 70 percent.
