A leaching technology on samples of Algerian quartz sand deposit has been investigated in order to obtain high-purity silica (SiO(2)) as raw material intended for photovoltaic application.
With voltage of 20 kV and 30 kV, few evident changes were found in the distribution of coal and quartz, showing that the enrichment of coal and quartz was minimal with relatively low voltage. However, with increase of plate voltage, the mass fraction of quartz particles near the positive plate increased while that near the negative …
