by geo-statistical tools. The limestone ore deposit was studied in this paper. The assay value of individual constituents of limestone ore i.e CaO, SiO 2, Al 2 O 3 and Fe 2 O 3 were determined for a block by using Inverse Square Distance Weighting (ISDW) method. The average assay value of those individual constituents were 45.85, 15.94, 1.56 and

Limestone is available in 50-pound bags, each occupying 0.5 cuft. Knowing that 1 cuft. is 7.481 gallons of water, we can determine that 13.4 lbs of limestone are required per gallon. In our example, that would result in over 2,300 lbs of limestone! Unfortunately, the limestone breaks down over time and needs to be replaced.
