Silver

Silver ore is added by several of the major tech mods Thermal Expansion 3, Factorization, IndustrialCraft 2, GregTech and RedPower 2. Silver Ingots are used in many crafting recipes.

Processing
Silver ore can be smelted using any smelting machine or furnace.

GregTech 6
As added by GregTech 6

Smelting
To double or triple ore output a crushing machine must be used. The dust from these machines will need to be smelted in a smelting machine.

MineChem
MineChem adds Silver in the form of test tubes which can be obtained from silver of other mods. With these test tubes other materials and elements can be created. For more information see.

Thermal Expansion 3
Silver can also be made by using Factorization's Slag Furnace, and putting either Silver Ore in or any other of the Factorization ore processing chain items.

World generation
Silver Ore generates with Lead Ore. They generate in veins with a maximum size of 8 blocks. At y levels 5 to 30, the veins are generally composed of a 4:1 ratio of Silver:Lead. At y levels 10 to 35 they are generally composed of a 9:1 ratio of Lead:Silver.

Uses
Silver can be made into Ingots or Dust at which point can be converted in to Nuggets or Storage Blocks It is also used to make Electrum Ingot

World Generation
Thermal Expansion 3, Factorization, GregTech, RedPower 2, and Immersive Engineering all generate some form of Silver Ore. Although IndustrialCraft 2 has a processing chain for Silver and recipes requiring it, it does not add Silver Ore itself.

Ore world generation is controlled in the config files of the mods that add it. They spawn independently from one another. CoFH Core is able to tweak the spawn rate of all modded and vanilla ores.

Immersive Engineering
Silver can be used to create the Silver Cartridge.

Config options
In the "ProjectRed.cfg" configuration file (in the "config" folder), the generation of Silver Ore can be disabled, and the generation can be reduced by increasing the resistance value. Furthermore, the enabling of the retro generation allows to generate the ore in an old world, which was started with older versions or without Project Red. "World Gen" { B:"Silver Ore"=true I:"Silver Ore resistance"=0 B:"Silver Ore retrogen"=false }
