Silver

Silver is a metal resource added by IC², but not generated as ore. Absent any other mods that generate it, silver is only acquired by processing  Gold Ore.

Forms

These forms of silver are seen during ore processing (the first two only if silver ore is generated):

•  Crushed Silver Ore
•  Purified Crushed Silver Ore
•  Silver Dust
•  Tiny Pile of Silver Dust

If silver ore is not generated, silver dust is acquired (in tiny piles) by running  Crushed Gold Ore or  Purified Crushed Gold Ore through a  Thermal Centrifuge.

Silver is not used in metal shaping. Currently^[2.6.133] its only non-dust form is as  Silver Ingot when smelted (which has no use, really).

Uses

Silver has a single use, albeit an extremely important one: crafting  Glass Fibre Cables.

• In addition to carrying power tier 5 voltage), these are used to craft the  Teleporter, which is used to craft the  Advanced Miner and  Replicator.

Each  Gold Ore you process will only get you 2x  Tiny Pile of Silver Dust, so 9 ore will get you enough for 2x  Silver Dust. Treasure your gold!
