The raw materials market, including for quartz, is today highly globalized.
To date it has been common mining practice to extract material first and then classify it according to quality.
The images clearly identify the locations of materials in the vein, whether silicon metal, ferrosilicon, aggregate or kaolin.

Experimental As starting material, high purity powders of electrolytic copper(<75μm)and titanium carbide powder(<45μm)were used.
The composites electric conductivity is connected with material composition and internal organization, also with the material milling process.
With increasing the milling time, deformation and fracture of powder filled in the pores, causing the relative density increased and porosity reduction, particle need to undergo large deformations to file pores, so reaches a certain density, prolonging ball milling time the material density increase is not obvious.
