Chromium pollution due to chromite mining. The Indian mining industry is an important economic activity that contributes significantly to strengthening the national economy. Around 90% of India's chromite resource reserves are concentrated in the Sukinda Valley of Anka chromite, applying magnetic separation.
Chromium (Cr) Ore Minerals. Chromium (Cr) ore minerals typically refer to the naturally occurring minerals that contain chromium in their composition. The most common chromium ore mineral is chromite, which is a dark, black to brownish-black mineral with the chemical formula FeCr2O4.
Chromium-rich mineralization was discovered in the Red Mountain area around 1910 and some limited mining occurred there during World War I. Knowing Red Mountain could provide a domestic source of chromium during World War II, the U.S. Bureau of Mines drilled more than thirty holes to evaluate this chromite-rich area near …

The abundance of chromite resources in South Africa, amongst other factors, has led to the development of the South African ferrochrome industry. The country's production accounted for around 34% of global ferrochrome production in 2013. Most South African producers have smelting facilities and chromite mines within the BIC .
The Coto Chromium Mine, located in Zambales, Philippines, was initially found in 1925. It was classified as a medium-sized mine in terms of its production output. The primary mineral extracted from this site is chromite, while the associated waste material consists mostly of magnetite, antigorite, and olivine.
