By Sierra Alvarez CAVE CREEK – Ten steel rods, each weighing 1,000 pounds, pulverize gold-bearing rocks into sand, releasing the precious metal from the ore, which is then further refined with mercury to extract every flake. This is a stamp mill, a 19th-century invention that saved miners from extracting precious minerals by hand, which …

The Argo Mill was completed in the early 1900s, soon after the 10-year Argo Tunnel operation was completed. In its time, the state-of-the-art milling techniques of the Argo processed over $100 million worth of gold ore!. The prices per ounce ranged from $18 to $35, meaning the mill operations were hard at work each and every day.
Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low …
Soft ore Work Index 13 = 100,000/90,000 = 1.1 kwh/t Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers.
