In general, the rarer the ore, the higher its volume per unit (e.g. one unit of Veldspar has a volume of 0.1 m 3, whereas one unit of Arkonor has a volume of 16 m 3). Since mining lasers mine a given volume of ore per minute, it takes longer to mine the rarer ore types. Additionally, each ore reprocesses into a different set of minerals.
