5 thoughts on “99.9%of the gold is not a pure gold”

  1. Calculate.
    Theoretically, 24K gold is equal to pure gold. In fact, the purity of 24K gold in various places is not exactly the same. The 24K gold in Japan and the former Soviet Union contains 99.99%of gold, most of the companies in South Africa and my country earlier are 99.6%, and the United Kingdom is 99.5%.
    This in Hong Kong. Macau in Macau is mostly> 95.84%, and the old jewelry before the founding of New China in my country is often 98.4%. However, my country's national standard GB 11887-2008 "Regulations and Name Methods" of the "Puritatics and Naming Methods", which was promulgated in 2008, has stipulated that 24K theoretical purity is 100%.
    Pucting information:
    The regulations on gold product marks and logo cards in my country. Generally, there are production enterprise codes, materials names, and content marks. Unsproductive books are unqualified products. The same is true internationally. But for some particularly small products, they are also allowed not to mark. 18K gold marks are generally the words AU750, 18K or G750.
    In May 4, 2016, the new national standard GB11887-2012 was officially implemented. There will be no "thousands of gold" and "24K gold" in the future. Gold jewelry with a gold content of more than 990 ‰ can only be marked as foot gold. For details, refer to the national standard GB11887-2012.

  2. 99.9%of the gold calculation pure gold
    The reason is:
    pure gold refers to 24K gold, which means that its gold content is 100%.
    Theoretically 100%gold can be called 24K gold, but in reality, it is impossible to have 100%gold.
    So China stipulates that gold with a content of more than 99.6%(including 99.6%) can be called 24K gold.
    The expansion information:
    The pure gold content in gold is called "gold position", English is karat, so it is called K gold.
    22K's gold content is 91.6%(22/24 = 0.916)
    20K's gold content is 83.3%(20/24 = 0.833)
    18k gold content is 75%(18/24 = 0.75) r r. The gold content of n14K is 58.3% (14/24 = 0.583)
    12K's gold content is 50% (12/24 = 0.5)
    10k gold content of 41.6% (10/24 = 0.416)
    gk The gold content of 37.5% (9/24 = 0.375)
    sk's gold content is 33.3% (8/24 = 0.333)

  3. Pure gold refers to 24K gold, which means that its gold content is 100 %. The pure gold content in gold is called "gold position", and English is karat, so it is called K gold. Generally called pure gold is 24K, that is, the theoretical gold content is 100%. Therefore, the gold content of 1,22K is 91.6%(22/24 = 0.916) 2 20K. 75% (18/24 = 0.75) 4 14K gold content is 58.3% (14/24 = 0.583) 5 12K gold content of 50% (12/24 = 0.5) 6 10K gold content is 41.6% (11/24 = 0.416) ) 7 GK's gold content is 37.5% (9/24 = 0.375) 8 SK's gold content is 33.3% (8/24 = 0.333). There are generally many in my country that use 18K to inlaid jewelry, so that the inlaid jewelry is relatively high. K gold refers to the alloy mixed with gold and other metals. Karat is the measurement unit of K gold. It is divided into 24 copies of pure gold. According to the gold content in jewelry, it is divided into different K gold, so 24K refers to pure gold. For example, 18K gold content is 18/24 = 75.0%, and because 18K gold content is 75.0%, it is also called 750.
    but I think it is relatively speaking at all, so this must be judged by yourself. If it involves natural science, 99.9%of the gold is impure.
