purification of uranium from ores

Ore - Wikipedia

Ore - Wikipedia

An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element or elements The ore grade, or concentration of an ore .
