The refining of gold Photo by Nankai University students Lidian Wu<br>Gold from waste where it is not a myth! A senior Nankai Institute, to use computer CPU refining scrap gold. Recently, a group of "old Wu CPU of gold a piece of cake" picture circulated on the Internet, attracting netizens exclaimed.<br> <br>Network diagram Live<br> <br>Seniors' sturdy gold extraction technique "<br> <br>All the Internet,http://www.badel.org, posted a total of 19 photos, including 13 small gold beads close-up. CPU from the first two pictures, to the fourth "Pharmacy debut mystery",barbour paris, to the seventh photos "4 Kim,moncler femme, a sneeze is I get to fly ......" picture broadcast of friends "old Wu "CPU refining with small gold beads in the process. Finally, the "old Wu" also excited to put up their use of the school spectrum devices were analyzed and identified three Kim outcome "three Kim,http://store.shopping.yahoo.co.jp/littletreasure/stafford-chino21.html, ICP-AES analysis at 99.99% Oh, no impurity peaks of other elements Oh". And on Renren and Sina Weibo, a group of more detailed, more intuitive picture clearly demonstrates the "sturdy old Wu thiourea gold extraction technique."<br> <br>"Old Wu" is actually a student at Nankai University Department of Chemistry, College senior, called . On the reason for thought "thiourea gold extraction technique",http://store.shopping.yahoo.co.jp/waiwai/prw-5000yt-1jf.html, "Old Wu" said his idea is very simple, is that when the waste electronic products directly sold on the pounds, too wasteful. In social practice after school, the "old Wu" gave a scrap acquired businesses to do the technical guidance, access to a lot of precious metals recovery approach. For this experiment, the "old weapons" has repeatedly stressed that this method is non-toxic,http://www.nard.com.cn/wMcms_GuestBook.asp, high purity, low cost, and the technology is already very mature, not the so-called "aqua regia method." "Old Wu" said he was completing the study in mid-November,http://maillists.freead.com.au/cgi-bin/mojo.cgi, "The experiment requires only one day to complete."<br> <br>Ten Steps<br> <br>5 CPU refining the four small gold beads<br> <br>"Old Wu" and "thiourea gold extraction technique" a total of ten steps. The first step is to prepare the instrument, be prepared beakers, glass, muffle furnace; the second step is to prepare reagents is thiourea, sulfuric acid, hydrogen peroxide and so on; The third step is to prepare CPU, "CPU ranging from gold, but 486,586 older computers gold more adequate "; the fourth step is soaked, washed with water first CPU, remove the thermal silica, etc., and then water immersion CPU, the dilute sulfuric acid to adjust the pH to about 1.5 and 30% 5 ml of hydrogen peroxide, 1 g of thiourea (preferably made of solution), the order can not be reversed; fifth step is activated carbon adsorption; sixth step is heated to high temperatures, temperature not lower than 1000 ℃,doudoune moncler femme, high temperature air until the charcoal is completely oxidized after the rest is yellow gold; seventh step is to use distilled water and pure nitric acid alloy slightly cook cook, direct filtration, washed repeatedly with water,http://mijessicajones.net/bbpress/profile.php?id=19997, thick gold came out; eighth step is purified,http://index119.com, probably took an hour; s nine steps and tenth step is the use of a muffle furnace to melt the gold, and instruments to detect the purity of gold.<br> <br>"Old Wu" said he used this method from the CPU 5, the final extract four small gold beads, which one is that it does not accidentally lost.<br> <br>User question:<br> <br>Too costly and polluting the environment<br> <br>For the "Old Wu" alchemy,air max 90, although there are a lot of friends with emotion, to find a "way to get rich,http://store.shopping.yahoo.co.jp/gion/gsr144v-lin2.html," but there are also netizens questioned the laborious, time-consuming, more users worry that high "indigenous" Alchemy cost and pollution of the environment, because " the CPU is now inside the metal did not before, did you get get to actually not earn anything. "<br> <br>Dr. Chemical:<br> <br>Operation need professional guidance<br> <br>In this regard, a chemical doctor told reporters, speaking from the steps, this approach is feasible in the laboratory. However, if you want to refer to this method,scarpe hogan outlet, the experiment, there should be an experienced chemist guidance, and be sure to pay attention to environmental protection.<br> <br> Share: welcome to comment I want to comment<br> Microblogging Recommended | hot microblogging today<br>
