Classification: Copper and copper alloys are considered an "article" and are not hazardous in its solid form. However, certain processes such as cutting, milling, grinding, melting and welding could result in some serious hazardous materials being emitted. The GHS classification below pertains to these emitted products during these processes.

Since metallic copper is malleable, it cannot be broken and pulverized as can the more friable minerals, and after first picking out the larger lumps or nuggets of copper by hand, crushing is done by steam stamps; pebble mills instead of ball mills are employed for grinding because of the abrasive qualities of the gangue.

Milling, Turning, and SawingLubricants for Aluminum and Copper. Also known as plumber's lard oil, these light-colored lubricants are chlorine and sulfur free, so they won't stain soft metal, such as aluminum or copper. They reduce friction between your cutting tool and workpiece to make cutting cycles faster and easier.

A process for abrasively grinding copper comprising (1) cooling the entire copper workpiece to a cryogenic temperature and (2) abrasively grinding the copper workpiece while it is at said cryogenic temperature. The workpiece is preferably immersed in liquid N2 during the abrasive grinding thereby preventing adhesive wear from occurring at relatively high metal removal rates.

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
