In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.
The ore box is made using the Smithing skill at an anvil. Ore boxes can be upgraded to hold higher level ores, this is done at an anvil with two bars and the previous ore box. Ore boxes can store 100 of each ore up to the level of the box (i.e. a Steel ore box can store 100 Copper ore, 100 Tin ore, 100 Iron ore .
Pure copper has an electrical conductivity value of 5.9×10 7 Siemens/m, making it the second most electrically conductive metal to silver, which has a value of 6.2x10 7 Siemens/m. As copper is far more abundant and therefore less expensive than silver, copper quickly became a popular method for transmitting electricity.
The extracted ore must be mill ed to prepare it for further recovery activities. Uniformly sized particles may be obtained by crushing, grinding, and wet or dry classification. The degree of milling performed on the ore depends on the gold concentration of the ore, mineralogy and hardness of the ore, the mill's capacity, and the next planned
