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.
The Gold Rush in California started in 1848 after gold was found at Sutter's Mill. Within a year, hundreds of thousands of 49ers seeking fortune poured into the state.
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 and Tunnel's storied history punctuates the scale of the Colorado Gold Rush and the ambitious businessmen who ravenously chased after golden opportunities buried underground. The 4.2-mile tunnel connected several mines in one of Colorado's richest districts. The Argo served these mines by draining hazardous floodwaters and ...

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.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
With a diameter of 8.2 meters and a length of 12.7 meters, this overflow ball mill is said to be the largest one made in China, marking a breakthrough in the country's …
