The Benefits of Recycling Vs. Extracting Raw Metal

It requires various machines for mining and refining raw materials, while recycling has considerably fewer energy costs. Energy is roughly 30% of primary aluminum production costs, while aluminum scrap uses 5% of the energy during production. Besides lower energy costs, scrap metal recycling can be even more efficient than mining .

Bioleaching and Biomining | SpringerLink

Abstract. Universal reserves of high-grade ores are diminishing at an alarming rate due to the rapid increase in the demand for metals. Biomining is the extraction of specific metals from their ores through biological means, usually microorganism. Biomining is done in two steps often called bioleaching and biooxidation.
