Abstract. Ore is defined as a mineral or mineral aggregate more or less mixed with a gangue, from which a metal or metals can be won at a profit or in the hopes of a profit.*. From this definition it follows that local production and transportation costs are a prime factor and what may constitute an ore body in one region may not do so in a ...

Instead, when valuing quarries, we look at several factors to come up with a final figure for their rateable value: The mineral element is calculated by multiplying the annual output of mineral by an adopted "royalty" per tonne. The "royalty" is a derived value that reflects not only the mineral being extracted but also the factors that ...

Many suppliers sell large quantities of gravel by the ton. Converting from cubic yards to tons requires knowing the density of the gravel; while this can vary, our gravel calculator keeps it simple by using the standard 2,835 lbs per cubic yard for density. Thus, 1 cubic yard = 2,835 lbs / 2,000 lbs = 1.42 tons.
