Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the …

Silica can be found in its pure form in some minerals. The most common places to find silica is in sand and quartz. The difficulty in extracting silicon from its natural form is due to its high melting temperature. Quartz ore is composed of quartz and silica sand. To extract the silica, the quartz ore is crushed to 25mm and then ground.

Joseph Swan (1828–1914) was a British physicist and chemist. In 1850, he began working with carbonized paper filaments in an evacuated glass bulb. By 1860, he was able to demonstrate a working device but the lack of a good vacuum and an adequate supply of electricity resulted in a short lifetime for the bulb and an inefficient source of light.
