The Argo Mill was constructed to process the gold bearing ore from these mines. When completed, the Argo would be the largest mill of its type in the world. The mill processed over 100 million dollars of gold ore. At that time, gold prices were $18.00 to $25.00 per ounce. Taking into account the difference in gold values between 1900 and 2017 ...
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

Today, the iron-ore industry uses HPGRs to prepare pellet feed for finishing grinding after wet-ball milling and filtering. The wet-ball mill product is more readily filtered without the need to grind it to the final product size. Since HPGRs can process fine ores at moistures of up to 10%, they are used to perform the final stage of grinding.
