Apr 17, 1979· Some of the arsenic remaining in solution is precipitated with the copper in the cementation stage. Copper is generally precipitated first, however, so that the amount of arsenic precipitated with the copper can be held at a very low level by holding copper recovery in the cementation stage to about 95%.
Recovery of copper and/or other metal values from pregnant, highly dilute liquors and conversion of the barren liquor to a suitable lixiviant; for recovery of copper or other metal values from leaching systems, such as acid treatment of mine waste dumps, vat or heap leaching and insitu mining as part of an overall copper recovery process.
Copper is traditionally known as the "red" metal after its natural color. However, it is also known as a "green" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look.
