High Li concentration in coal seams has been reported by several papers in recent years. However, there is no minimum mining grade (or minimum economic grade; or ore border grade; or cut off grade) for lithium in coal seams because associated Li ore deposits in coal seams have not been found until now. In this paper, the minimum mining grade is suggested by compared the Li enrichment in coal with the Geology and Ore Deposit Standard Specifications in rocks for Rare Metal Mineral Exploration of the People's Republic of China (DZ/T 0203–2002), and also compared with the minimum mining grade for Ga and Ge in coals.
