ball mill. The maintenance costs and availability of the Tower mill are the same when compared to the equivalent ball mills (Ramsey, 1982; Stief, 1987). Several Australian companies have installed Tower mills as a device that can produce a fine product with a significantly lower power draw (Glen et al, 1991).

Lead-210 is particularly useful for helping to identify the ages of samples by measuring its ratio to lead-206 (both isotopes are present in a single decay chain). In total, 43 lead isotopes have been synthesized, with mass numbers 178–220. Lead-205 is the most stable radioisotope, with a half-life of around 1.73 × 10 7 years.
