you how much lithium is in the deposit which happens to be a pegmatite. The two minerals you are specifically interested in are Spodumene and Lepidolite. The company gives you the following information. The pegmatite is 10m wide, 500m long and at least 100m deep. From initial assay results the rock averages 5% spodumene and 10% lepidolite. Your company sent out some samples for electron probe microanalyzer data and the lepidolite came back at 2 cations of Lithium in the molecular formula of Lepidolite based on 22 oxygens. 1. Balance out the chemical formula for lepidolite. 2. Write out which site Lithium resides in for Spodumene and Lepidolite and coordination number for lithium for each mineral? 3. Determine how much lithium is in the deposit. 4. Supporting information: Inosilicates general formula is the following: XY(Z2O6) Mica's general formula is the following: X[12]Y[6]23(Z[4]4O10)(OH)2 Spodumene's chemical formula is: - LiAlSi O6 Lepidolite's chemical formula is: - K2(Li,Al)(6)(Al(21)Si([7))O20(OH)4
