Purification of metallurgical grade silicon by acid ...

The purification of metallurgical grade silicon (≈98% Si) from Companhia Portuguesa de Fornos Eléctricos by acid leaching is studied as a function of the particle size, time, temperature and concentration of leaching agents (HNO 3, H 2 SO 4, HCl and HF). It was found that using only hydrochloric acid (16%, 5 h, 80°C) and a relatively coarse fraction (116 μm) it is possible to remove .

The Effect of Citric Acid on Metals | Hunker

Metal corrosion. Strong acids corrode metals rapidly. Strong acids react by oxidizing a metal, changing a pure elemental metal into a metal oxide. Adding strong acid to elemental iron will react to produce iron oxides or rust. Adding strong acid to nickel creates nickel oxide, a greenish blue crust that appears on coins left outside in the rain.

Silicon - Wikipedia

The properties of silicon may be used to modify alloys with metals other than iron. "Metallurgical grade" silicon is silicon of 95–99% purity. About 55% of the world consumption of metallurgical purity silicon goes for production of aluminium-silicon alloys (silumin alloys) for aluminium part casts, mainly for use in the automotive industry.
