Silicon wafer with mirror finish. Most elemental silicon produced remains as a ferrosilicon alloy, and only approximately 20% is refined to metallurgical grade purity (a total of 1.3–1.5 million metric tons/year). An estimated 15% of the world production of metallurgical grade silicon is further refined to semiconductor purity. [79]
This is a list of silicon producers. The industry involves several very different stages of production. Production starts at silicon metal, which is the material used to gain high purity silicon. High purity silicon in different grades of purity is used for growing silicon ingots, which are sliced to wafers in a process called wafering.

Spruce Pine district is one of the largest suppliers of high-purity quartz, which is used in the manufacture of silicon for integrated circuits. [2] The district is named after the town of Spruce Pine, which is located in the middle of the region and is the hub of major mining activity there. The district is approximately 25 miles (40 km) long ...
Some statistics on this page are disputed and controversial—different sources (OPEC, CIA World Factbook, oil companies) give different figures. Some of the differences reflect different types of oil included. Different estimates may or may not include oil shale, mined oil sands or natural gas liquids.
In Silicon Valley and New York, venture firms had amassed billions in dry powder to invest in crypto projects. It was the was perfect time for Al-Naji’s next act.
In 1970, South Africa produced 995 tonnes or 32 million ounces of gold, two-thirds of the world's production of 47.5 million ounces. [2] Production figures are for primary mine production. In the US, for example, for the year 2011, secondary sources (new and old scrap) exceeded primary production. [3]
