| Here argentiferous galena was obtained, and the mine was worked for its silver. |
|
| As already mentioned, lead occurs in British Columbia, mainly in the form of argentiferous galena or silver lead ores. |
|
| Some of the richer argentiferous galena pockets contained masses of mineral three or four inches in size. |
|
| These are always argentiferous in a high degree, and their colour varies from light-yellow to pure silver-white. |
|
| The total production to 1926 was about 5,000,000 tonnes of argentiferous galena from around 300 mines and prospects. |
|
| Regarding the technical process, treating amorphous slags consist in smashing and washing them in order to pick off argentiferous lead bullets. |
|
| Normally, in mineralogy, argentiferous gold containing 20-25 per cent of silver is referred to as electrum. |
|
| Since ancient times this area was famous for its argentiferous minerals. |
|
| In a few places the lodes were so argentiferous that they supported operations which were primarily silver producing, with little associated lead output. |
|
| Although argentiferous lead drift was prospected for years after its discovery, it was not until 1909 that a regular deposit was found by Bessie and John Dunbrack. |
|
| Discovery of argentiferous galena at Anse à la Mine, Lake Temiskaming. |
|
| Most true silver deposits, as opposed to argentiferous deposits of other metals, came from Tertiary period vulcanism. |
|
| So the primary production of silver requires the smelting and then cupellation of argentiferous lead ores, a historically important process. |
