GOLD RECOVERY FROM CERAMIC PROCESSORS(Scrap CPU)

Gold recovery from scrap CPU ceramic processors is very easy and profitable business. Ceramic processors have a good ratio of gold. Different processors have different quantity of gold.Some types of ceramic processors are below.

  • AMD
  • 486
  • Intel PRO
  • Cyrix
  • 386
  • Intel

Scrap CPU(ceramic processors) recycling method is so easy. You can easily recover gold and silver and make money. For these processors, you don’t need to prepare anything like ic chips you will need to remove from electronics boards first. Let’s see which items we shall need.

  • Plastic Bucket
  • Filter Paper
  • HNO3 (Nitric Acid)
  • H2SO4 (Sulfuric acid)
  • HCl (Hydrochloric acid)
  • HF (hydrofluoric acid)
  • SMB (Sodium Metabisulfite)

If you are a newbie then please learn about GOLD RECOVERY CHEMICALS and GOLD RECOVERY EQUIPMENT first!

Recycling:

PART-1.

I recommend you have to make minimum 2kg scrap CPU batch for recycling. First, Break all ceramic processors. The inner silicon glass of every processor should break because mostly ceramic processors have gold plated surface under the silicon glass.

After the break, all ceramic processors put them into a large size bucket. Add water until processors dip. Now add nitric acid double of water. For example, If you add 1000 ml nitric acid then add 100 ml sulfuric acid and 100 ml hydrofluoric acid. Leave it in open area or under the hood for 8 hours. Shake bucket 3 to times during this period. After reaction done, you will see floating gold foils in the solution. Filter the solution with filter paper or fabric that can stop all gold foils neatly. After that repeat this acid treatment on processors for complete base metals removing. Leave it again for complete reaction.After the second time, base metals will remove. Filter again and wash ceramic processors with water two times.

  1. Thank you for you great and helpful videos, i think video part 2 is missing, i want know why should i put soda with borax?
    when you add sulfuric acid what it should do?did it precipitate lead in metallic form?
    please, mention the ratios of materials.
    thank you again

  2. Hello, you extracted gold and silver from solution, but there is Pb metal group in solution, please tell us how to extract them

  3. السلام عليكم نظريا اكاد اكون ملم بالمواد والخطواط ولكن عمليا ينتابنى القلق بسبب نسب المواد والوقت وتتابع وضعها
    حمض نيتريك
    حمض هيدروكلوريك
    حمض كبريتيك
    حمض هيدروفلوريك
    ميتابسلفيت صوديوم
    يوريا
    صودا
    كلوريد القصدير
    كلوريد الامونيا
    كلوريد الصوديوم
    ارجو الافاده عن المواد بالضبط

  4. Salam o 3alaykoum, thanks again ,I work for a long time with ceramic processors , but with different processes ,for example for 1kg mixt ceramic processors I get between 2g untel 3grams not more.

  5. Thanks for sharing nice videos.bro how much ceramic chip is used in this video? In weight kg.

    Thank you,

    Waiting for your replay.

  6. Thanks for reply
    Please share the process for this also or just tell I can use iron rod in the same Nitrite solution after extracting silver.

  7. hello there
    I was processing ceramic cpus and at the first part of process, instead of hf i added hcl, so i dissolved all metals in a mixture of hno3 hcl and h2so4 of course by mistake! no the gold is dissolved in this mixture,
    i added urea and tried to extract gold but when i add smb , smb react with something ells, can you help me?

    1. check the gold in solition with stannous chloride test . if solution is clear then filter it and reuse aqua regia on residue! hope it will help, ( intelligent lets the follish work first) keep it in mind

  8. Salam aleykom mr umar
    I added urea and some water and powder the shoping sead (smb but not sure ) to AR .but nothing happen .solution change color and is dark grean .can i add solfat iron ll ? Please help me kindly
