<&alu>§lBauxite Ore§r can be found in the world between layers <config;i;ores.bauxite.min_y> and <config;i;ores.bauxite.max_y>, and requires a pickaxe or tool of stone or better to harvest.
The raw ore will smelt into aluminium ingots, which are an integral part of high-voltage architecture.
<&lead>§lLead Ore§r can be found in the world between layers <config;i;ores.lead.min_y> and <config;i;ores.lead.max_y>, and requires a pickaxe or tool of iron or better to harvest.
The raw ore will smelt into lead ingots, which are used in creating early accumulators, bullets, and industrial dyes.
<&silver>§lSilver Ore§r can be found in the world between layers <config;i;ores.silver.min_y> and <config;i;ores.silver.max_y>, and requires a pickaxe or tool of iron or better to harvest.
The raw ore will smelt into silver ingots, which can be used in mirrors or alloyed with gold to create electrum, a far more effective conductor.
<&nickel>§lNickel Ore§r can be found in the world between layers <config;i;ores.nickel.min_y> and <config;i;ores.nickel.max_y>, but more abundantly below <config;i;ores.deep_nickel.max_y>. It requires a pickaxe or tool of iron or better to harvest.
The raw ore will smelt into nickel ingots, which can be used in accumulators, or  alloyed with copper to create constantan, for use in <link;thermoelectric_generator;Thermoelectric Generators;start>.
<&uranium>§lUranium Ore§r can be found in the world between layers <config;i;ores.uranium.min_y> and <config;i;ores.uranium.max_y>, and requires a pickaxe or tool of iron or better to harvest.
The raw ore will smelt into uranium ingots, but there are few uses for the metal. Uranium blocks can serve as heat sources for the <link;thermoelectric_generator;Thermoelectric Generator;start>, and the metal will be used in future endeavours.
