Many people believe that when that computer no longer works the only thing it’s good for is a paperweight the clutter of their desks but they couldn’t be more wrong. Men work for a new breed of recycler who has discovered gold in old hard drives.
Hidden within your old computer is a treasure trove of precious metals. The circuit board contains silver and copper and the microprocessor is laced with gold. All of which are good conductors the tarried electrical signals around your computer.
The old computers are sent to a plant which salvages their precious metals.First the outer casings are taken off. Cables are unplugged and disposed of and then all the remains on a chips and processes. All these components were worth a fortune when they were brand new but now they would be worth nothing if they were on a rubbish pile. Companies who are recycling this computers will make a handsome profit though one ton of old computers could fetch them six and a half thousand pounds. Micro processors are the easiest to recycle as the only metal contained in them is gold a mix of hydrochloric acid and nitric acid is used to separate the gold from the ceramics.
Hundreds at a time and dissolved in a large barrel what remains is pure gold dust. This is melted into gold boolean the stuff of dreams for any business. Other parts of the computers interior are a lot harder to recycle since theycontain a mix of metals for the effort is still well worth while. The metal parts are stripped down and put into a furnace. They melt into a liquid mix of gold silver and copper which is poured out cooled pressed and then sliced in two plates. Each plate is placed into a bath and given a positive charge. On the left on the right and negative charge copper plates attracts the copper particles which loosen from the mixed metal plates and accumulate there.
In the next bath steel plate attracts the silver which forms and crystals. After the second bath the plate contains nothing but gold and could be melted down it will be shaped into different forms that have a variety of uses. Using a sheets can be used to make gold salts which will be sold to the computer industry. To create the salt crystals from the sheets they have to use cyanide which is highly poisonous so the engineer make sure the container is sealed very tightly. This salt may not be so good for fishing chips but it is excellent for computer chips.
The gold sheets are pinched into small plates that will become dental crowns what once carried information around a computer memory will surely find a home in someone’s mouth. Measure gold rods from the furnace that compressed and twisted into a coil which is then transformed into fine wire used in computer circuitry. Another industry that has a huge demand for gold is the space industry. Satellites and vehicles such as the Space Shuttle use gold in their engines everyone knows gold is a precious metal but who would have thought that would have so many industrial uses all of these combined to make recycling old computers a very lucrative business.
Recycling with any important materials like computers, metals, gold and plastics can have a great advantage to our economy, environment and technology. Using the trommel fines you can get the ideal waste materials to recycle.
