Calculate the gross value of a lithium mine : geology - reddit

You need to convert that mass into mass of Li2CO3. Molecular weights are what you need here. Li2O is MW=29.9 (about) and Li2CO3 is MW=73.9 (about), so 1 tonne of Li2O is 73.9/29.9=2.47 tonnes of Li2CO3. Your 1.4 million tonnes of ore would have 5900x2.47= 14,500 (about) tonnes of lithium carbonate.
