Ok, the Russian pins form last time were overkill and I'm still bummed out i can't get any Russian stuff. But Italy is just around the corner, I'm in Austria. Awesome yield and great video once again!
So when you refine the gold a second time or even three times why melts the gold powder? I learned to just throw the mud in a clean beaker and some hcl than add a pipette of nitric until all gold was dissolved
Когда то и я с такого материла золото снимал, но его у нас было намного больше. хорошее видео. Once I also removed gold from such material, but we had much more of it. good video.
Привет с Германии.Спасибо за информацию. Огромный Лайк и просмотр. Ест тоже почти такой же материал. Надо испробовать также. Так как реально такие платы большие только так. Здоровья и успехов. С У Александр.
Hello, thank you very much. Dear friend, I am watching the video from Iran. I would like to explain the details of the video in Farsi and enable the Farsi subtitles. Thank you.❤❤❤❤❤❤
Hello dear golden man. I'm going to ask you a question, if you answer I would be very happy. My question is: How can we get rid of nickel, tin, solder and copper alloys on boards before removing the gold plating on computer motherboards and key phone cards? Can citric acid, water and nitric acid remove tin, nickel, copper and solder alloys on cards?
Excellent video! Thank You! Just to make sure I understand correctly - the first step with the citric acid is only to remove the solder - correct?? Thanks again!
great video.i would like to try this.would this ratio work on CPU pins to take the solder off..how many ml of nitric acid did you use in the first stage with the citric acid......is the key just to have the right amount of nitric and citric acid together for this to work..other wise I'd presume to much nitric in the first step.would dissolve all baseetals like the 2nd stage..hope for a speedy answer as i would really like to try this method...love your videos.thanks you
Hi I have 15 pieces of computer RAM. I dissolved them all in Aqua Rija solution. I definitely have copper, lead, tin and gold in the solution. Can I precipitate all metals, including gold, by adding sodium metabisulfide? What is your suggested opinion?
I'm in south east USA the e scrap is plentifully lots of MLCCs and tantalum caps off the side of the road free I depop the boards separate all components wish I had a nice closeup pic of the best things to save all this is side work so far the MLCCs look the most promising need more videos on them
Hola que tal un gusto al ver visto tus videos, me resulta muy interesante. Tengo una consulta a ver si puedes ayudarme, primeramente soy de ARGENTINA, mi nombre es MATIAS y mi consulta es de donde podria comprar materiales como *PENTIUM PRO* en varios kilos y traerlos para argentina sin tener ningun problema ya que aqui en mi pais por lo que eh averiguado no se permite ingresar esas clases de materiales. Tienes alguna empresa confiable que me puedan vender a buen precio y enviarmelo a mi direccion sin ningún compromiso? desde ya MUCHAS GRACIAS, SALUDOS TOTALES.
Wasting HCL to remove solder. I think this method is better: What should I look out for in the ratio of water + citric acid + nitric acid? gold particles should not be attached to the filter ...
Hello.... Would you please clarify more about the stages of work, for example, what temperature should the solution be at each stage when neutralizing the nitric acid and when putting the meta, thank you
Dears, may I ask you, do you know why the ceramic processor in USA / South Africa is so cheap than Asia? Do you thinks is it scammer? Kindly inform if you know, thank you very much
