how is copper extracted via milling
AN INTRODUCTION TO COPPER EXTRACTION
2.2 OVERVIEW OF COPPER EXTRACTION The copper extraction process begins at an open cut mine where Copper Ore is blasted and removed via Excavators and Tip Trucks. The ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor. When the crushed ore falls onto the

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 ...

The average crystallite size extracted from the broadening of all peak widths labeled in Fig. 1a using the Scherrer equation is about 49 nm for milled powder, versus 56 nm for raw ones [12,13]. Obviously, the milling does not pose much effect on reducing the crystallite size; but, importantly, it does affect the particle size significantly.
