1. Calculate the gold content: First, we need to know how much gold is contained in the motherboard of the phone. Typically, electronic components are used in mobile phone motherboards, some of which contain small amounts of gold. Gold content is usually expressed in grams per ton (g\/t) or ounces per ton (oz\/t). The exact amount depends on the manufacturer and model of the motherboard. A common figure is 2 to 10 grams of gold per ton of motherboard.
2. Calculate the refining ratio: Refining gold requires a smelting and purification process. In reality, the efficiency of gold extraction is very low, usually only about 80 to 90 percent of the gold can be extracted. Therefore, we can assume an extraction ratio of 0.8 to 0.9.
3. Calculate the amount of purified gold: Assuming that the weight of the mobile phone motherboard is 1000 grams (1 kg), we can calculate according to the above data. Taking a hypothetical value as an example, if each ton of motherboard contains 5 grams of gold, then 1 kilogram (1000 grams) of motherboard contains 5 grams of gold. Then, depending on the refining ratio, we can multiply this value by 0.8 to 0.9 to get the amount of purified gold.
In summary, according to the gold content and refining ratio of the mobile phone motherboard, we can calculate how much gold can be purified from the 1000g mobile phone motherboard. Please note that these values are only assumed and actual conditions may vary. In real-world applications, gold extraction of mobile phone motherboards is a complex and costly process, so the specific value may vary due to various factors.
The amount of gold in the 1000g mobile phone motherboard is very small and almost impossible to extract.
The amount of gold in mobile phone motherboards is very small. Although the electronic components in the mobile phone motherboard will contain a small amount of metals, including gold, silver, copper, etc., the content of gold is very small, only a few milligrams.
In the actual refining process, it needs to be refined through several steps such as high temperature and high pressure, which is very complicated.
And even if extracted, its content is very small, very difficult to use.
The gold in mobile phone motherboards, although almost useless, the total amount of gold contained in e-waste is large.
For the gold in e-waste, we can recycle and reuse it through environmentally friendly e-waste management. At present, many countries and regions have begun to promote e-waste recycling, hoping to gradually solve the problem of gold waste in e-waste.
Huang Weijuan, vice minister of environmental management of the company, dismantled a used mobile phone for reporters at the scene. Ms. Huang explained that the contacts in the integrated circuits embedded on the phone's motherboard are plated with gold,
In addition, some places are silver plated, and the base plate contains copper. Among them, the content of gold in mobile phones is 0.015 percent. \"The idea that 100 million mobile phones can extract 1.5 tons of gold is theoretically feasible,
But in practice it is impossible.\" Yang Guixing, general manager of the trading center, said that gold plating on the main board is mainly for better electrical conductivity, and it can indeed be refined, but the gold content in a mobile phone is actually very small.
