(1) In a few places the lodes were so argentiferous that they supported operations which were primarily silver producing, with little associated lead output.(2) This design provides decisive benefits: Placed on the wound, the argentiferous ointment dressing releases silver ions from its surface on contact with the exudate.(3) The total production to 1926 was about 5,000,000 tonnes of argentiferous galena from around 300 mines and prospects.(4) 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.(5) Some of the lodes of the region of Val di Castello consist largely of ferrous sulphide, whereas those of the Argentiera consists mainly of argentiferous lead sulphide, zinc, antimony and other metals.(6) Some of the richer argentiferous galena pockets contained masses of mineral three or four inches in size.(7) Here argentiferous galena was obtained, and the mine was worked for its silver.(8) Normally, in mineralogy, argentiferous gold containing 20-25 per cent of silver is referred to as electrum.(9) As already mentioned, lead occurs in British Columbia, mainly in the form of argentiferous galena or silver lead ores.(10) These are always argentiferous in a high degree, and their colour varies from light-yellow to pure silver-white.(11) The mines of Foxdale and Laxey have yielded from time to time for many years immense quantities of argentiferous lead of a high class, at very good profits to the shareholders.(12) He reported that most highly argentiferous galena required silver to have been coupled with bismuth or antimony to allow a substitution for lead within the lattice under high-temperature conditions.(13) Regarding the technical process, treating amorphous slags consist in smashing and washing them in order to pick off argentiferous lead bullets.(14) Gold-bearing quartz and argentiferous galena [ore containing silver] have been discovered in several places.(15) Since ancient times this area was famous for its argentiferous minerals.
