Copper Concentrates

For example, they are used for comminution of porous copper cake. A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening.

Copper Smelting

2.1.1.6.1 FeO–Fe 2 O 3 –SiO 2 Slags. It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces now use basic refractories. Viscosities of slags are important ...
