This project is for Science. We are currently learning about the Elements and Periodic Table.We researched about the minerals in our technology that we normally use.
About the iPhone:
The company Apple develops the technology. The cost of the iPhone 7 is ¥72,800 and the cost of the iPhone 7 Plus is ¥85,800. You can call people, email, take notes, play games, text people, etc. If you want to know more about the iPhone go check the website.
The Materials in this technology are Platinum(Pt), Aluminium, Gold(Au), Silver(Ag), Copper, Yttrium(Y), Lanthanum(La), Praseodymium(Pr), Praseodymium(Pr), Neodymium(Nd), Europium(Eu), Gadolinium(Gd), Terbium(Tb), Dysprosium(Dy), etc.
In iPhone Gold is used in the Micro-Electrical parts of the phone used for electrical connection inside the phone. Also, phone arena said that “The shiny metal is primarily used for the wiring inside of chips due to its excellent conductivity and malleability properties. These allow it to conduct signals very effectively across the incredibly thin chip wiring.”
It can be used for many different kinds of things. For example, you can use it as a jewelry, crowns, fillings (teeth), coins, electronics and so on.
It is in Witwatersrand Basin (Johannesburg, South Africa) which is the number one place that has Gold. According to metal super market.com Gold is 70% conductive compared to Copper, It is 19.32 g/cm3 dense, 1064.18C is the melting point and Gold is the most Malleable of all known metals.
It affects the environment by making a lot of amount of toxic waste and also causes global mercury pollution. It also ruins the view and pollutes the river with sulfuric acid.
The safety issue for Gold:
It causes some issues with safety but mining gold could be really dangerous and it could cause illness, injury or even death. They need to do lots of lifting work and that causes back pain to a major issue. The risk could be higher for the 60,000 children who works as gold miners. The children sometimes do not get paid. They are in a dangerous situation and earn a really little amount of money which leads them to poverty. Because they have the low income they don’t have electricity and water at their house.
We can help by starting to buying fewer electronics that contains gold. For example, iPhone, computers,etc. This is happening because we buy way too many things with gold in it, mostly electricity. Also, the company should start making smaller phones so that they could use less gold inside the phone. At the YIS community, I think that we can start making the numbers of the iPads fewer and buy less computer less each year. If we do that we will be able to use the computers till it won’t work and also if we use it till last we won’t need to buy much and that means we won’t get much Gold.
This would help because if we start buying fewer products with Gold in it, it will make the mining process go slower since there will be more stocks at the store and then eventually we can bring the number of gold miners down.
