Question
Since the price of Lithium metal is currently at $129.91/kg, your exploration company has determined that they want to explore the potential of reopening the Harding Mine. To determine if a deposit is economic for mining, a company size of the deposit, the grade or concentration, mining costs and clean up/'environmental remediation costs. That is a lot to think about before they even start mining! You must overcome the production costs for the mine to be profitable must first look at the Make sure to show the units in every calculation: work in kg and meters. Provide Calculations on a separate sheet of paper! 1. Given that the pegmatite density is 2650 kg/m and the estimated volume of the main dike is 8,480,565 f' ( f-0.0283 m2), calculate the tonnage (i.e., mass) of the deposit. (1 tonne 1000 kg)Explanation / Answer
The tonnage of the deposit is calculated using volume and density. It is given that 1 m3 of pegmatite has a mass of 2650 kg. The volume of the deposit is 0.0283 m3. Thus, the mass of the rock in the given volume is
0.0283 x 2650 = 74.99 kg or 0.0749 tonnes
Hence, the tonnage of the pegmatitic ore deposit is 0.0749 metric tons.
