00:00:20.340 --> 00:00:23.940 the non magnetic multilayer ceramic capacitors are weighted 00:00:55.460 --> 00:00:58.480 a fire brick is used as scorification dish 00:01:17.160 --> 00:01:21.120 lead is heated until it melts, then the MLCCs are added 00:02:03.100 --> 00:02:07.640 when the capacitors floating above the molten lead are glowing red, silver is added 00:02:19.880 --> 00:02:23.180 the silver is heated until it dissolves in the molten lead 00:02:56.560 --> 00:02:58.080 then more lead is added 00:03:19.960 --> 00:03:27.960 once the mixture is glowing red, oxygen is blown above it, until the molten metal covers with scoria, containing the base metals oxides 00:04:15.260 --> 00:04:17.740 the last portion of slag is poured off 00:04:25.120 --> 00:04:29.320 the dore is then moved to the cupel to eliminate the last trace of litharge 00:05:37.240 --> 00:05:40.080 42.52g dore 00:05:42.600 --> 00:05:46.620 slag is remelted to recover any trace precious metals left 00:08:29.040 --> 00:08:31.280 0.4g dore 00:09:04.480 --> 00:09:08.640 both dores are dissolved in 50:50 nitric acid to water 00:11:05.240 --> 00:11:10.360 something strange appeared during the dissolution - black particles resembling gold 00:11:14.840 --> 00:11:17.340 it will be confirmed in the following video 00:11:58.920 --> 00:12:00.060 Thanks for watching!
