As early as 1602 a stamp battery working in Cornwall was described, and in 1671 calcination and buddling was a recognised scheme of treating pyritic ore. In the first half of the 16th century the output of tin from Cornwall was 700 tons per annum, and, from then on, production increased to the maximum in 1914 of 6500 tons.
With a primary focus on grinding appliions, OMC was instrumental in the wide acceptance of SAG milling to the Australian mining industry. Over the years, a database compilation of project information and ore characterisation testwork has captured OMC's extensive project experience.

treatment by simply grinding and amalgamation. They require a chloridizing roasting after which they are amalgamated in barrels. The ore is first reduced to a suitable size for stamping, and then dried. The drying kiln consists of a series of flues, covered by a castiron floor on which the ore is spread to a depth of about 5 inches. The kiln has a
