12.3 Primary Copper Smelting

2015-9-10  Mining produces ores with less than 1 percent copper. Concentration is accomplished at themine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percentcopper. A continuous process called floatation, which uses water, various flotation chemicals, andcompressed air, separates the ore into fractions. Depending upon the chemicals used, some mineralsfloat to the surface and are removed in a foam of air bubbles, while others sink and are reprocessed.Pine oils, cresylic acid, and long-chain alcohols are used for the flotation of copper ores.

Milling Process, Defects, Equipment

Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached to a platform inside the milling machine.
