Recycling metals: A circular approach to mining

Mar 12, 2015  The concept of recycling or urban mining does not mean that mining should totally be abandoned. As long as the global demand of metals continues to grow, the world needs mining. In addition, recycling is not a perfect process as it is impossible to perfectly separate and recover all basic ingredients through recycling.

Mine Waste Transfer and Disposal Methods - Mine Tailings ...

When extracting the seams, the additional waste rock will be removed to get to the actual ore, called gangue. Then, as the material is processed and finely ground, even more, waste, called mine tailings, will need to be removed from the site. Overburden -> Gangue -> Tailings. Overburden. Waste rock, or overburden, refers to the often large mass ...

Mining and Refining – Process

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Recycling - Wikipedia

Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its virgin or original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas ...
