They have found an incredible way to produce gold. It’s all about technology

New ways to farm gold from old technology may hold the key to the future

Gold is one of humanity’s most precious metals. It is a noble metal that has as many applications as we want to give it. In fact, one of the main is in consumer electronics. Yes, the latest generation gaming computer with which you play your favorite titles has precious metals like gold. In fact, it is not the most valuable material that your PC or console may have, there are others that are even more expensive and rare that have caused the price to rise in recent times.

There are countries that are totally dependent on most metal resources. Something that happens specifically with South Korea as pointed out by EurekAlert. The country has to face an increasing shortage in the foreign market, so it is necessary to find a more efficient operation of the circular economy to fully exploit the resources that the country already has.

A necessary step in recycling and reuse

In the heat of the great shortage of metals, Korea has developed a quite interesting plan in which it will try to improve a 30% recovery of very scarce metals such as gold or copper. The idea is to get them through the waste arising from semiconductor manufacturingsince even if they try to make the most of it, there are always metals that remain among the general garbage when it comes to create this type of devices so necessary today.

Korea is a country focused on the technology industry, so its semiconductor factories are large and require many materials. For this reason, the Korea Institute of Science and Technology (KIST), the country’s main research institution, has developed a technology that allows recovering high purity gold of electrical and electronic waste. For this they have used textile materials.

Granular adsorbents are normally used, but their use underwater is poor, so recovery rates are low and the increase in pollution is notable. From KIST they have used a very interesting new technology based on fibers so that they are easier to operate underwater and can have different shapes depending on the weaving process. This has allowed him to have many applications and it makes a lot of sense.

They have used polyacrylonitrile fibers (PANF) on which they have immobilized alkaline molecules to allow the gold recovery performance and its structural stability. Apart from the fact that the recovery rate is double compared to the current method, this allows high purity gold to be recovered. By trying to recycle real CPUs it has been achieved recover 99.9% of the gold they hadan incredible step forward that also It is widely reusable since after 10 uses it maintained a recovery rate of 91%.

Gold developments continue to be downright impressive, being one of the metals on which the most research is done. In fact, they have now achieved a way to make gold in two dimensions with some truly amazing new features.
