Companies that make circuit boards often reclaim copper from copper containing solutions. This allows them to reuse the copper or sell it. Based on your results from the investigation you conducted in class, which metal would you recommend a company use to reclaim copper? Support your answer with evidence, and identify the trade-offs of your decision.
To reclaim copper with solids I would use iron. Even though the wate produced is also haazardous thatcan just be taken to a treatment center. The advantages are much greater than the amount of disadvantages so I believe it is fine to use iron in this situation. It is incredibly creap, priced at only .02 cents.
ReplyDeleteI would use aluminum to reclaim the copper from the copper chloride solution because it successfully reclaims almost all of the copper in the solution. This means that after this is done the solution is considered nontoxic and can either be disposed of or even reused. However, aluminum is somewhat expensive, but considering the fact that it allows the copper to be recycled and the solution to be reused or thrown out, I believe it's the smarter choice.
ReplyDeleteI would use incineration to dispose of the waste because of the fact that the hazardous waste is reduced in mass and we can put more of it in landfills. I believe that all other methods are not as effective because they either use too much water when diluted, are too costly to buy the material to reclaim with a solid, or are just too time consuming, like reclaiming using a solution.
ReplyDeleteI would reclaim the copper from the used copper chloride with aluminum. It does pull out all the copper(showed in previous experiments), it does it quickly, it does it safely. There is no mess , compared to reclaiming the liquid. Plus, Im sure you can reuse the aluminum washer again and again, without having to worry about it rusty, or breaking. So even if it is the most expensive, it'll be cheaper in the long run.
ReplyDeleteI would use sodium carbonate to reclaim the metal from the used copper chloride solution because it is the cheaper than the other solution used to reclaim metal, and also it is the 2nd cheapest option. I would use sodium carbonate because of the fact it reclaims copper better than sodium phosophate, and it doesn't not include much busywork. You may have to wait a while for the solution to reclaim the metal, but once it does, it's an easy clean up of just disposing the salt. Salt is something that won't harm the environment when you dispose of it, unlike other options that leave you with precipitates that could harm the environment (such as iron chloride, etc). We have to be careful of human health and the Earth's safety when we reclaim copper, and I think sodium carbonate is a safe option.
ReplyDeleteI think aluminum would be the best metal to reclaim copper from copper containing solutions. It reclaims all the copper from the solution. Plus, it is unbelievably cheap. The process is very neat. In my experiments of reclaiming copper, aluminum successfully reclaimed the copper, as the ammonia had showed me. Once again, I believe you should use aluminum to reclaim the copper.
ReplyDeleteIn this situation I would choose iron because its the best to reclaim copper. And when we did it in class you can clearly see why. A few reasons are that its cheap, and reusable. But a few things that the company should watch out for is that the disposal is highly restricted and the substance should be diluted. Thats why iron is the best for reclaiming copper.
ReplyDeleteIf I had to pitch to a company which material for getting rid of the coppper clordie i would suggest to them, that they should use Iron. Iron is a very good and strong metal. When we dropped it in the solution ,when we tested it, it got rid of alll the copper in the solution. Not only that, but it is a very afforable price and you can reuse it numerous times. A few things that they should watch out for would be that the disposal is highly restricted and that the substance should be diluted. That is why the company should choose iron for the best way to reclaim copper.
ReplyDeleteIf i were to pitch to a company which material is best for reclaiming the copper from the solution, I would say the aluminum. Mainly i would choose this material because it is the most reliable at reclaiming all of the copper. It reclaimed ALL of the copper from the 100,000 ppm solution.For example, in our experiment when we put the aluminum washer into the solution it chemically reacted and all the copper was extracted from the solution. Therefore making it the best choice for reclaiming.Not only is it the most reliable but it's very cheap!Lastly, I would highly recommend using aluminum to reclaim the copper because it the VERY reliable and cheap at the same time.
ReplyDeleteIf I were to recommend a company, that makes circuit boards, to use any type of metal to reclaim copper. I would tell them to use sodium charbonate. There are many resons on why I decided to choose this. The first reson is because the sodium carbonate is cheap. Yes, of course there is also the option of iron if a company is aiming for a cheap way to reclaim copper, but the downside of useing iron is it's harmfulness to our environment. To dispose iron there would be many steps to do it, but with sodium carbonate it is quick and easy to throw away the dissolved salt that was produced from the reaction. There is also the arguemeant of aluminum, which is said to be also easy to be disposed and okay for the environment, but to compare the prices. Aluminum costes $1.30 per pound while sodium carbonate costs only $0.07 per pound. Lastly, there is also sodium phosphate. People may say that it is almost the same, and it kinda is, but sodium phosphate costes 2 more cents then sodium carbonate. (Every penny counts) Also in pass labs, sodium carbonate, reclaimed the copper the best compared to other options, by only leaving a few copper existing left. So, I think I would recommand a company to use sodium carbonate.
ReplyDeleteOMG! Where did all the comments go? Please post again...you have until next Monday...
ReplyDeleteThe best metal to reclaim copper from copper containing solutions is aluminum. According to my experiments, aluminum reclaims all the copper from the solution, unlike zinc. This process is very safe. It is an extremely clean procedure, too. Once again, aluminum is the best metal to reclaim copper from copper containing solutions.
ReplyDeleteThe best metal to I recommend for companies is probably reclaiming the copper by using metal. Why? Well, you can reuse the copper that is reclaimed for other processes. Aluminum would be the best the to reclaim metal and you are saving a lot because with diluting it you are just throwing it away and this you are actually getting something out of it.
ReplyDeleteIf I were to recommend a circuit boards company, on what kind of process they should use to reclaim the copper that is needed for them to use and sell. I would recommend the company to use reclaiming copper with matels, using aluminum. Saying this, many others could argue about it's price and such, but when one thinking about it, the company can actually save money. When using aluminum, based on a recent experiment, the product of the reactant is the copper that is needed. But people can say that zinc and iron also gives the company copper only. But the problem with zinc is that the price is way too high, and it's restricted disposal, while iron is a cheap price but also has a restricted disposal of waste and to disposal those waste comes another process that takes time and money. There is also the srgue meant of using sodium cardonate and phosphate. But those would only give you the carbonate/phosphate of copper not the copper itself. So I would recommend using the metal aluminum.
