Chapter 6 Copper Production Technology

2 Hydrometallurgy is the recovery of metaIs from ores using water-based solutions. As early as 6000 B. C., native copper–the pure metal—was foundas reddish stones in the Med- iterranean area and hammered into utensils, weapons, and tools. Around 5000 B. C., artisans discovered that heat made copper more malle-able.

Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

What Are the Advantages of Wet Grinding vs. Dry Grinding?

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
