Recovering precious metals via e-waste recycling is 13 times cheaper than extracting these metals from mines.

“Our company will collect and recycle all of these metals mentioned, as well as several other types of metals and recyclables.” In fact, these valuable metals were some of the metals that TDS harvested in the company’s early days.

“Metals have been recycled for thousands of years, but in the last 50 years or so, we’ve seen some interesting developments, particularly in fields using granulation methods to pull out more metals with less effort,” Gregory said.

As Gregory explained, “Liquisort’s bath separates metals with dense water and magnet systems to better the purity of metals. This granulation process is a relatively new one, and when combined with shredding options of electronic waste, this reduces the need for hand-separation and increases the amount of metals that we can recycle, particularly from electronic waste.”After going through several layers of separation and granulation, precious metals will create a fine mesh or powdery-like substance,” Gregory said.

“As structural metals are becoming smaller, we’re seeing a sweeping change from industrial and oil field metal waste coming in for metal recycling to more electronic waste.

Using microorganisms to selectively and quickly recover precious metals, such as gold, Mint Innovation can extract these precious metals from electronic waste.

In addition to these innovative precious metal recycling technologies, some key trends of precious metal recycling that industry players need to focus on include innovation in bulk shredding processes, in mechanically sorting metals and in emerging parts of the smelters/refiners global market.
