Resource Recycling of Non-Ferrous Metals | SpringerLink

Abstract. This chapter focuses on non-ferrous metals, their resources, extraction and recycling. Mining of these metals (copper, zinc etc.) causes major environmental damage through open mining techniques, and thus improving recycling rates has major environmental benefits as well as potentially economic ones.

3 Methods of Nonferrous Metal Recycling

However, both methods are largely unreliable as the first method relies on human intervention and observation, while the second method relies on the density of said materials. The problem arises because some of the non-ferrous metals are of similar densities so they will not be separated from each other using gravimetric techniques.

Biomining - Wikipedia

Biomining is the technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons.

Surface Mining Methods and Equipment

pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from low-grade deposits by surface mining.
