LIGATUR MELTING ON A LEAD COLLECTOR LIGATUR MELTING ON A LEAD COLLECTOR The video for voiceover and editing was kindly provided by the channel - expert. - https://www.youtube.com/@user-ux9im6h... The video shows one of the options for gold mining from ore and metals in the alloy of which there are precious metals (mainly gold), for separating precious metals from alloys with by-product metals and further purification of impurities, but already by chemical methods. This method is also suitable for working with parts and ligatures that have gilding both by spraying on the surface of ligature metals and in the alloy in the form of relay contacts with mixed precious metals. Such smelting was used by our grandfathers on the rock, but now you will be presented with work with gilded ligature from radio components, which in addition has solder, and it is not worth removing it, since the solder also contains gold that got into the tin-lead solder by diffusion of gold, tin and other by-product metals. It is also interesting that palladium was found in the lead that was used in this experiment, which in the middle of the last century was just beginning to be studied and did not have much value. Watch, comment. And write whether it is necessary to shoot such videos, for example, in the form of analysis for errors in refining?
