مصنع لتجهيز البوكسيت/what is the process of mining silicon
The element silicon is used extensively as a semiconductor in solidstate devices in the computer and microelectronics industries. For this, hyperpure silicon is needed. The silicon is selectively doped with tiny amounts of boron, gallium, phosphorus or arsenic to control its electrical properties.
Silica is mined from the earth and is found in sand, rock and quartz. Because silica has a dioxide component, it must be taken to a plant, where it is converted to silicon through a heating process. According to the United States Geological Society, there are 16 mines and plants that yield silica,...

Energy is one of the inputs of the mining and purifying process. The output is purified silicon, which gets shipped to a computer chip factory. The computer chip factory then takes the purified silicon and makes it into a crystal wafer form. The purified silicon is an input of the manufacturing process. Only about 43% of the pure silicon crystal used in the process becomes part of the chip.
