The Odisha Voluntary Health Association (OVHA) reported that 84.75% of deaths in the mining areas and 86.42% of deaths in the nearby industrial villages occurred due to chromite mine-related diseases.

The Sultanate of Oman started mining chromite ores and exporting these ores since early 1980s. However, metallurgical grade chromite ores started to be exported in the last few years primarily in response to rising demand from China and general shortages of ferro chrome worldwide in the production of stainless steel.

A second period of extensive chromite mining came during the late 1860's and early 1870's. Production figures are incomplete and conflicting. Estimates from the available data indicate that the aggregate production from 27 of 40 known mines before 1900 totaled between 250,000 and 280,000 tons of lode-chromite ore; information is lacking for the ...

Estimates from the avail­ ... high-grade mines now flooded have not been completely explored. Although other chromite deposits probably lie concealed at relatively shallow depths, no practical method of ...

Chromite ore mining is a typical mining industry with substantial environmental hazards. Chromium metal derived from industrial chromite mining is used in the production of stainless steel, leather industry, paint industry, and other important industrial usages [].Nevertheless, the presence of chromium ions, particularly hexavalent chromium (Cr(VI)) in …

The Lagonoy High Grade Chromium Mine is located in the province of Camarines Sur, Philippines. This mine primarily utilizes surface mining techniques to extract chromium deposits. The mining operations were first established in 1975 and include underground workings. There is a single known shaft within the mine.

Turkey has a 6% share in the world's chromite mining and possess 25 million tons of reserves (Uyanik, 2010). In Aladag (Adana, South Turkey) a low-grade chromite deposit (5.42% Cr 2 O 3 grade) with 200 metric tons reserve has yet to be exploited. Chromite demand in Turkey is mostly met by metallurgic-type ores.
