The old mobile phone with ash in the corner is quietly using it to

The old grey cellphone in the corner is being quietly used to "alchemy". Experts have made statistics that at least 150 grams of gold, 100 kilograms of copper and 3 kilograms of silver can be extracted from a ton of old cell phones, while a ton of gold ore can only extract about 5 grams of gold. Robot system "Liam" dismantling iPhone6 process recently, with the release of a lot of new cell phones such as iPhone7, many people have switched their original phones to a new product with stronger function and more eye-catching appearance. Many of the phones that have been changed have entered the chain of product recycling. Experts have made statistics. At least 150 grams of gold, 100 kilograms of copper and 3 kilograms of silver can be extracted from a ton of old cell phones, while a ton of gold ore can only extract about 5 grams of gold. According to the report published by the Apple Corp, only 1 tons of gold, worth 260 million, had been dug out of the used cell phone in the last year only. Robot 11 seconds dismantling a iPhone6 at present most mobile phones are composed of four parts, the shell, the LCD screen, the circuit board and the battery. Mobile phone shell is mainly composed of engineering plastics, aluminum, stainless steel and other components; the main components of mobile phone LCD is indium metal and glass; mobile phone circuit board accounted for 15%-25% of the weight of it, and mobile phone batteries contain gold and silver, copper and nickel and other precious metals and non-ferrous metals, almost every part can be recycled. In mobile phone manufacturers, both apple and the domestic Meizu have published their own mobile phone recycling chains. The enterprise can do so not only for environmental protection and social responsibility, but also conceals huge business opportunities behind it. In the first half of this year’s product launch, Apple introduced a robot system called Liam. Its main purpose is to extract valuable metal materials from old phones. This is also an action that Apple has been responding to criticism from the outside world. Apple’s mobile phone design is very small, but the process of dismantling is very difficult, affecting the recycling of old mobile materials or refurbishing and reselling. According to the plan, Liam can carefully dismantle many components of the iPhone, including the SIM card tray, screw, battery, and camera. Liam has 29 mechanical auxiliary arms. Some arms are fitted with bits, and some are screwdrivers or suckers. As a machine designed for iPhone6 and the dismantling of the structure of the iPhone6 robot, it is well known, the moment will be able to be the glue Yan Yan is really really suck down iPhone6 screen. Even tiny screws can’t get rid of Liam. After the components are tested, the tentacles of Liam will screw the screws down and give them to the vacuum sucker, and put all the screws removed. Each workspace has a small display screen that tracks the internal components of the robot and tracks the processing process of the device. If there is a problem when the component is disassembled, such as being stuck in the shell, the screen will tell you "try to fail". If the temperature of the battery is too high, the system will pay attention to it. If it is recycled by the old method, the magnetic rip machine is usually used, and it is difficult to distinguish the parts together. Liam can be highly accurate to separate the internal components of the iPhone, for example, it can ensure that the glass and plastic will not be mixed with copper. After doing this, a iPhone6 cell phone becomes a pile of waste, which takes only 11 seconds. The disassembled components will be resale to recyclers. These recyclers focus on producing raw materials, such as nickel, aluminum, copper, cobalt and tungsten. Raw materials can be recycled instead of thrown into garbage dumps. The use of special chemical solution from the circuit board "alchemy" a processing of second-hand mobile phone, will slowly release of heavy metals and lead, mercury and other toxic substances, the soil damage even if 100 years cannot repair; one did not go through the formal treatment of mobile phone batteries, about 6 tons of water pollution. But if you can make good use of it, you can turn it into a treasure. Statistics have been made that at least 150 grams of gold, 100 kilograms of copper and 3 kilograms of silver can be extracted from a ton of old cell phones, and only 5 grams of gold can be extracted from a ton of gold ore. We can say that gold content in mobile phones is much higher than that in gold ores. The waste cell phone is such a valuable "gold mine". Its mobile phone manufacturers are not only stared at, but also some research institutions have joined the Nuggets operation with the support of the government. But this is not easy, and the process of recycling will also cause pollution. When the precious metal is attached to the electronic component as a raw material, if you want to recycle it, the first step is to disconnect it from the electronic component of the mobile phone. But most of them are done by chemical methods rather than by the stripping of physical methods. For example, mobile phone containing gold, old gold on the mobile phone can be used to obtain from the aqua regia, concentrated acid aqueous solution containing gold ions. In this process, the strong acid solution produced in this process can not return to nature, and it will cause high pollution to the soil. To solve this problem, scientists at University of Edinburgh have developed a simple gold extraction method, which does not use toxic chemicals, and the recovery efficiency of gold is higher than traditional methods. The researchers say this method is expected to be able to recover about 300 tons of gold in electronic equipment each year. The team figuring out the complex chemical mechanisms behind the extraction process, and they found that a compound could be more efficient in recovering gold. The team invented the method first to soak the printed circuit board in an electronic device in a weak acid and dissolve all the metal parts. Then an oily liquid containing the above compound is added, which can selectively extract gold from the mixed solution of all metals. The team said the study would help develop a large scale recovery of gold and other precious metals from abandoned electronics. The study was published in the German Journal of Applied Chemistry. After ATM Street into the old mobile phone recycling kiosks will spit money from the old mobile phone in the end dig gold, the rest of the plastic and glass, as well as pollution larger battery and other components will be how to deal with? The UK’s largest mobile phone repair business and recycling company "Fonebak" approach is the mobile phone after the demolition of every parts, each make the best use of raw materials. Cell phone batteries are sent to special factories, and lithium and nickel are recycled, such as nickel for frying pan, iron and new batteries. The metal containing plastic parts are sent to a special processing plant for heating, and the heat generated is used for heating in the local countryside. After burning, the metals, such as platinum, gold, silver and copper, are extracted and sent to professional companies for treatment and reuse. All of the above are the way to deal with the waste cell phone entering the recycling business, but how can we get people to send the idle cell phones to these right places, and then deal with them in the right way? The simplest way is to give money directly. An American company has developed a ATM recycling booth for electronic products. The process is: "the old cell phone is in, cash out". Every day, there are 50 thousand similar ATM recycling kiosks in the United States to recycle their phones. Put the old cell phone in the window and start some steps according to the hint of the touch screen. The kiosk first looked at the visitors, compared the image to the data Gallery of the 4000 types of mobile phones collected by ecoATM to quickly determine the model of the mobile phone. It also looks at the appearance of the mobile phone to see if the screen is broken, and there is no damage to the appearance. Then connect the phone with the corresponding cable, test its performance, and use complex computer operation rules to estimate the price of the mobile phone, and then report the price it is willing to pay on the screen. The ATM kiosk can erase all the data in the phone, even if the phone is not worth it, and the user can still receive a small gift.

角落里吃灰的旧手机有人正悄悄用它“炼金” [摘要]有专家做过统计,一吨废旧手机中至少能提炼出150克黄金、100公斤铜和3公斤银,而一吨金矿石则只能提取约5克黄金。机器人系统“Liam”拆解iPhone6过程近来,随着iPhone7等一众新手机的发布,不少人都换掉了原来的手机,换上了功能更强大、外观更抢眼的新产品。这部分被换下来的手机,不少进入了企业的产品回收链,有专家做过统计,一吨废旧手机中至少能提炼出150克黄金、100公斤铜和3公斤银,而一吨金矿石则只能提取约5克黄金。据苹果公司公布的报告,仅去年一年就从废旧手机中挖出了1吨黄金,价值2.6亿。机器人11秒拆解一部iPhone6目前绝大多数手机都由外壳、液晶显示屏、线路板、电池四部分组成。手机外壳主要由工程塑料、金属铝、不锈钢等组成;手机液晶显示屏的主要成分是金属铟和玻璃;线路板占手机重量的15%-25%,它和手机电池中都含有金、银、铜、镍等贵金属和有色金属,几乎每一个部件都可以回收利用。 手机厂商中,苹果和国内的魅族都曾公布过自己的手机回收链。企业这么做可不仅仅是出于环保和社会责任,背后还隐藏着巨大的商机。今年上半年的产品发布会上,苹果曾对外介绍了一个机器人系统,名为“Liam”,主要目的是提取旧手机中的有价值金属材料。此举也是苹果回应一直以来外界批评的举动。苹果的手机设计十分小巧玲珑,但是拆解过程却十分困难,影响了旧手机的材料回收或者重新翻新再销售。按照规划,Liam可以很小心地拆解iPhone的许多组件,包括SIM卡托盘、螺丝、电池、摄像头。Liam有29只机械辅助手臂。一些手臂安装了钻头,一些安装了螺丝刀或者吸盘。作为一台专为拆解iPhone6而生的机器人,它对iPhone6的结构了如指掌,一瞬间就能把被胶水粘的严严实实得iPhone6屏幕吸下来。甚至细小的螺丝也难不倒Liam,在完成部件检测后,Liam的触手会将螺丝钉拧下来,交给真空吸管,把所有被拆掉的螺丝钉放在一起。每个工作区都有一块小型显示屏,它可以追踪机器人的内部构件,跟踪设备的处理进程。如果拆卸组件时碰到了问题,比如卡在了机壳中,屏幕会告诉你“尝试失败”。如果电池的温度过高,系统也会注意到。如果按老方法回收,一般都要用到磁性撕碎机,零件混在一起很难区分。Liam可以高度精准分拆iPhone内部组件,例如,它可以确保玻璃片、塑料不会和铜混合在一起。做完上述动作,一部iPhone6手机就变成一堆废料了,而这一过程只需要11秒。拆解的组件会转售给回收商,这些回收商专注于生产原材料,比如镍、铝、铜、钴、钨,原材料可以循环利用而不是丢进垃圾堆。利用特殊化学溶液从电路板“炼金”一款不加处理的二手手机,会慢慢释放重金属和铅、汞等有毒物质,其对土壤造成的伤害即使100年也无法修复;一枚未经过正规处理的手机电池,大约能污染6吨的水源。但如若能善加利用,就能变害为宝。有人曾做过统计,一吨废旧手机中至少能提炼出150克黄金、100公斤铜和3公斤银,而一吨金矿石则只能提取约5克黄金,可以说手机中的含金量远超金矿石。废旧手机是如此有价值的“金矿”,盯着它的不光是手机厂商,一些研究机构在政府的支持下,也加入了这场掘金行动。但这并非易事,回收过程同样会产生污染。贵金属作为原材料附着于电子元件之后,如果想要回收,第一步要将其从手机电子元件上脱离。而脱离多数都是通过化学方法完成,而不是物理方法的剥离。比如说手机中含有金,将废旧手机上的金脱离可以采用王水,从而获得含有金离子的浓酸性水溶液。而在此过程中产生的浓酸性水溶液是不能返归自然的,会对土壤产生高度污染。针对这个难题,英国爱丁堡大学的科学家研发出了一种简单的金提取方法,这种方法不使用有毒化学物质,而且金的回收效率比传统方法更高。研究人员表示,用这个方法预计每年能够回收电子设备中大约300吨的金。该团队弄清楚了这种提取过程背后的复杂化学机制,他们发现有一种化合物可以更有效地回收金。该团队发明的方法首先要把电子设备中的印制电路板浸泡在一种弱酸中,把所有的金属部件溶解掉。然后加入一种含有上述化合物的油性液体,它能够从所有金属的混合溶液中选择性地萃取金。该团队表示,这项研究有助开发从废弃电子产品中大规模回收金以及其他贵金属的方法。该研究发表在《德国应用化学杂志》上。街头ATM回收亭放入旧手机就吐钱从旧手机里掘完金之后,其余的塑料、玻璃,还有污染更大的电池等部件会怎么处理?英国最大手机维修商和回收公司“Fonebak”的做法是,将手机拆卸后,让每个部件、每种原材料物尽其用。其中手机电池会被送往专门工厂处理,锂和镍被回收利用,如镍可用来制煎锅、熨斗和新电池等。而含金属的塑料部分送往专门加工厂燃烧,产生的热能用于当地农村供暖;燃烧后提取其中含有的铂、金、银、铜等金属材料,送往专业公司处理后再利用。以上说的都是废手机进入回收企业后的处理方式,但如何能让人们把闲置的手机送到这些正确的地方,然后用正确的方式处理掉呢?最简单的方法就是直接给钱。美国一家公司研制出电子产品ATM回收亭,它的流程是:“旧手机进去,现金出来”。每天,美国有5万台类似这样的ATM回收亭在回收手机。将旧手机放入窗口后,根据触摸屏的提示启动一些步骤。回收亭先对来者“看”上一眼,把图像与ecoATM收集的4000种手机的数据图库进行比对,迅速确定手机的型号。它还扫视手机的外观,看看屏幕是否破碎,有没有外观损害。然后用相应的电缆接通这台手机,测试它的性能,还能运用复杂的计算机运算法则,估算该手机卖出的价格,然后就在屏幕上报出它愿意支付的回收价格。ATM回收亭可以现场抹掉手机中的一切数据,即便手机一文不值,用户仍可以收到一份小礼物。相关的主题文章:
