this mining operation. The process is currently unprofitable with a gold price around 300 per ounce. Process Description Unit 100 Size Reduction of Ore The BFD of the overall process is shown in Figure 1. The PFD for Unit 100, shown in Figure 2, is designed to reduce tons/hr of gold ore from a feed range of 25" to 160 microns.

CNC milling process. A CNC milling machine uses a rotating cutter in a cylindrical shape. The plasma cutter moves in multiple Axes. The plasma cutter creates slots and holes in the material that later turns into a part. Standard machines operate on three to five axes. That makes precise cuts and more detail than on 2 Axis.

Treating ore by milling is generally a twostep process, first the ore must be crushed, then the crushed ore must be treated to separate the valuable mineral content from the waste rock. Elaborate milling operations at Tomboy, Colorado. The earliest, and simplest method of crushing ore was the use of arrastras.

the milling process takes place during rotation as a result of the transfer of kinetic energy of the moving grinding media into the grinding product. The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product.

Cyanidation. The gold cyanidation process is the most important method ever developed for extracting gold from its ores. The reasons the widespread acceptance of cyanidation are economic as well as metallurgical. It usually obtains a higher recovery of gold than plate amalgamation and is easier to operate than the chlorine or bromine process.

The cooled dore bars are secured in the refinery safe and the slag is fed manually into the ball mill for reprocessing. The production rate of the EXAMPLE Gold Mines processing plant is expected to be approximately 4000 troy ounces of combined gold and silver (dore) per day. Each refining day will produce 81000 troy ounce dore bars.
