Plant Operator

Plant Operator is responsible for operating the three carbon adsorption systems. The system consists of three circuits, one containing 6 columns filled with 6 tons of carbon each, the second unit consisting of 5 columns with 3 tons of carbon in each column and a third unit consisting of 4 columns with 3 tons of carbon in each column. Two Pregnant solution or gold bearing solution pumps distribute solution upward through the columns through a perforated diffuser plate that gently lifts and expands the carbon bed. Overflow from #1 c/c flows by gravity into the bottom of #2 c/c and travels similarly down to c/c #6 or c/c #5. The gold from the Pregnant solution adsorbs into the carbon in each column. By the time the solution overflows the final column, essentially all the gold has been removed, making it Barren solution. The now screened barren solution, flows by gravity to the barren sump. This is where cyanide is added. Three barren pumps then pump the cyanide treated solution back t...
