Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.

Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.
be measured as alpha-Quartz. The crystalline silica content in the respirable fraction is calculated back to a percentage in the bulk sample. Some iron ore samples were tested for recovery by mixing 4 g of the ore with 1 g of very fine Quartz powder (app. 60% respirable). The recovery of respirable Quartz was >97.5 % for Quartz/iron ore mixtures.
The iron ore slimes were in situ sieved and analysed with 94.4% present as < 25 microns particles. The sub-25 micron fraction contained 58.8% Fe, 5.74% SiO 2, 6.65% Al 2 O 3 and 0.15% P. The bulk mineralogical analysis of iron ore rejects slime is shown in Table 1 which contained about 13% silica and alumina gangue minerals. It was used as ...
