  • Metal Types and Recycling Process

    Mar 05, 2021Shredding is done to promote the melting process as small shredded metals have a large surface to volume ratio. As a result, they can be melted using comparatively less energy. Normally, aluminum is converted into small sheets, and steel is changed into steel blocks. 4. Melting.

  • Gold CIL CIP Gold Leaching Process Explained CCD

    Jan 02, 2013CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.
