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.
- Intel PRO
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)
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.
