How to recycle gold and silver from cpu computer scrap | Old CPU Scrap Gold Value

hello friends today I will recycle gold and silver from the old CPU computer warning chemical is very dangerous you should strictly protect in every step you have to wear gloves mask or protective clothing when you work when extracting gold finish you must clean thoroughly with water immediately and learn all kinds of chemicals that you used and how thoroughly protected old non-functioning computers are found in bulk and business closings school auctions and even on Craigslist for free [Music] the CPU is nearly always covered with the heatsink the CPU has a small throw switch which needs to be u B to open that up there is a strap as well that holds the CPU to the heatsink the Pentium Pro is a sixth generation x86 microprocessor developed and manufactured by Intel introduced in November 1st 1995 it introduced the p6 microarchitecture sometimes referred to as AI 686 and was originally intended to replace the original Pentium in a full range of applications wild opinion and Pentium MMX had 3.1 and 4.5 million transistors respectively the Pentium Pro contained 5.5 million transistors [Music] Gold is usually located at the junction of electronics outdated electronics are likelier to produce parts with a high enough level of gold to make the procedure worthwhile [Music] [Music] once you are done accumulating all the metals it is time to cash out look for a scrapyard near you you can also sell the motherboards Rams CPUs PCI's gold fingers and other gold plating parts online be careful dealing with online vendors selling these items on eBay is a good idea as it normally pays more than what you can get from a scrapyard this video light how to recycle gold from CPU computer scraps of the light to see that the gold content list in CPU and gold volume of course science and experimental work to find secret results we do not focus on price time profit or loss it will not be good for people to look at the value of money today I will recycle gold and silver from the old CPU computer I used an old CPU computer 20 pcs in a plastic socket [Music] put 2 liters of water in a plastic coffee with one liter of nitric acid in a plastic bucket [Music] to day of nitric acid [Music] seven day of nitric acid it takes about seven days for the CPU pins to come off and the silver dissolved chemical water filters we will precipitate the silver from the chemical water before going to gold recycling [Music] [Music] [Music] I use salt to make silver precipitate in solution [Music] it is an easy way we will get more silver from recycling gold electronics usually consists of silver and gold it is a great feature of the spectrum and various electrical signals you will see a white precipitate in solution similar to the color of the milk [Music] [Music] precipitate the silver [Music] claim precipitate the silver with two to five times hot water [Music] restore silver medal with you yet [Music] [Music] [Music] clean precipitate the silver with hydrochloric acid 35% [Music] clean precipitate the silver with two to five times hot water [Music] [Music] I use a hot-air gun to drive precipitate the silver you will receive silver powder ready for melting [Music] sprinkle little borax powder slightly to melt silver better [Music] [Music] [Music] it will not become a metal silver smelting may take a little time [Music] [Music] use water mixed with hydrochloric acid one-to-one for cleaning silver [Music] [Music] this is the silver sample and received if you are interested in silver let's do it [Music] [Music] continue with the recycling of gold from the CPU I smashed a piece of gold in a CPU to allow access to chemicals [Applause] [Music] the cpu gold will have gold plated pins outside the CPU and the inner parts that I have smashed bring all together [Music] today I used gold stripper to extract gold normally gold stripper one liter kid dissolved gold 25 grams this information from my trial normally gold stripper one leader Kim dissolved gold 25 grams this information from my trial today I do not use AR aqua regia [Music] [Music] [Music] [Music] [Music] [Music] [Music] Gold stripper will dissolve gold as the main for the CPU the ceramic will take to dissolve the gold about one hour [Music] [Music] [Music] you will see gold disappeared but other types of metals remain unlike antler a Jia the metal is decomposed gone missing [Music] I will use potassium hydroxide to make gold and solution go to the island with zinc powder [Music] [Music] [Music] [Music] [Music] [Music] you will get zinc powder with gold stick use nitric acid mixed with water separate gold from zinc powder [Music] [Music] [Music] [Music] you will get gold sludge the purity is not very high I solve this problem might bring golden sludge to boil with nitric acid mixed with slight water [Music] [Music] [Music] clean gold sludge with hot water three to five times [Music] [Music] [Music] [Music] [Music] [Music] drei gold sludge [Music] you will get the old powder ready for melting [Music] sprinkle little borax powder to make gold better melted [Music] [Music] [Music] hope you liked our compilation please share it and subscribe watch also our other videos then meet again in the next clip thank you very much [Music] you you
