12.3 Primary Copper Smelting

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.

What Is Copper Smelting? (with pictures)

A typical process might begin with grinding of the ore into a powder. This powder is processed with chemicals and air to separate out some of the unwanted material and concentrate the copper. Unwanted material from this step is referred to as the tailings.

During the process, the two wheels rotate in the same direction but with the grinding wheel at a higher speed than the slower regulating wheel. Unlike traditional OD grinding machines, in centerless grinding the workpiece is not held between centers or chucked. Instead, the workpiece is supported on its outside diameter by a workpiece rest blade.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.
