How is silicon metal made, the main grade classifiion …
Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive in non-ferrous alloys.Silicon metal is produced by smelting quartz and coke in the electric heating furnace. The content of main component silicon is about 98% (in recent years, 99.99% Si content is also contained in silicon metal), and the remaining impurities are iron, aluminum, calcium, etc.

Presolar grains - Wikipedia
Presolar grains are interstellar solid matter in the form of tiny solid grains that originated at a time before the Sun was formed. Presolar stardust grains formed within outflowing and cooling gases from earlier presolar stars.The stellar nucleosynthesis that took place within each presolar star gives to each granule an isotopic composition unique to that parent star, which differs from the

How is Molybdenum Extracted - SAMaterials
The molybdenum mineral recovered by flotation is molybdenite. The flotation agent uses non-polar oils as collectors, and a foaming agent is added. In order to ensure the quality of molybdenum concentrates, we need to further separate copper, lead, iron and other metal minerals and calcium oxide and carbon minerals from molybdenum concentrate, can use sodium sulfide, cyanide to inhibit iron

Cosmic dust - Wikipedia
Cosmic dust, also called extraterrestrial dust or space dust, is dust which exists in outer space, or has fallen on Earth. Most cosmic dust particles measure between a few molecules and 0.1 µm.Cosmic dust can be further distinguished by its astronomical loion: intergalactic dust, interstellar dust, interplanetary dust (such as in the zodiacal cloud) and circumplanetary dust (such as in a

Carborundum may grind out eco-mode UPS - DCD
Silicon carbide - or carborundum - can increase double-conversion efficiency to 99 percent, and end the worry about eco-mode However, a change from silicon to silicon carbide (better known as carborundum or occurring in nature as the extremely rare mineral moissanite) can increase UPS module efficiency to 99 percent in double-conversion.
