The process of extraction and recovery of copper from its slag involves three stages. During the first stage, the slag is fed to the flotation process. This process results in a rougher concentrate containing about 10,33 % copper. This rougher concentrate is then processed to extract the valuable metal. This process is repeated until the desired concentration is achieved. During the third stage, the recoveries are higher, but there is still a certain risk of the slag contaminating water.
