Uranium is a relatively common metal, found in rocks and seawater. Economic concentrations of it are not uncommon. Quantities of mineral resources are greater than commonly perceived, and are relative to both market prices and cost of extraction. The world's known uranium resources increased by at ...

Bronze Age source of tin discovered. A University researcher has found, for the first time, a local Bronze Age source of tin in the Middle East, a discovery that shows that tin the metal that makes the alloy bronze possible was not entirely imported from regions outside the area, as archaeologists had previously thought.

Underlying physical and chemical processes of formation are common to many metallic and nonmetallic ore deposits. A good deal of data is lacking about the processes of ore formation, ranging from how metals are released from source rocks through transport to deposition and postdeposition alteration.

Tin ore is an ore used to create the metal alloy bronze. Tin ore, along with copper ore, is the first ore a player can mine through the Mining skill, and the rocks it is mined from are found at various mines .
