gold ore for calcium carbonate

Gold ore can be mined at level 40 Mining providing 65 Mining experience. After a gold rock is mined, it will take 60 seconds until it reappears. Gold ore is used to smelt gold bars. Smelting a gold bar gives 22.5 Smithing experience, or 56.2 with the goldsmith gauntlets equipped. The bar can then be crafted into various types of jewellery through the Crafting skill at a furnace, rather than an ...

    It appears to give a higher recovery (82%) of gold than some of the earlier papers dealing with refractory gold ores. It looks very good for a refractory ore. Also, it runs at ambient temperature (25oC) rather than higher temperatures usually used with refractory ores (i.e., pressure oxidation, roasting).
