Where both overlap, USGS data is prioritized.\n- As BGS does not provide global data, we calculated the world total by summing the data from individual countries, using this as a cross-check against USGS global figures.\n- Due to the inherent uncertainties in the data for certain minerals and countries, we allowed a maximum deviation of 10% between the global totals reported by USGS and the calculated ones for BGS. If the deviation exceeded this threshold, we excluded the BGS data.\n- The calculated global total from BGS data was used only on exceptional occasions, after ensuring that the resulting aggregate was sufficiently complete.\n- Both BGS and USGS datasets include numerous notes and footnotes. We have retained most of these, making only minor edits or deletions where necessary to maintain clarity.", "type": "int", "grapherConfigIdETL": "019b2c95-e044-7f8f-9d53-463e85647434", "datasetName": "Minerals", "updatePeriodDays": 365, "datasetVersion": "2025-12-15", "nonRedistributable": false, "display": {"unit": "constant 1998 US$ per tonne", "shortUnit": "$/t"}, "schemaVersion": 2, "processingLevel": "major", "presentation": {"titlePublic": "Chromium unit value", "topicTagsLinks": ["Metals & Minerals"]}, "dimensions": {"years": {"values": [{"id": 1900}, {"id": 1901}, {"id": 1902}, {"id": 1903}, {"id": 1904}, {"id": 1905}, {"id": 1906}, {"id": 1907}, {"id": 1908}, {"id": 1909}, {"id": 1910}, {"id": 1911}, {"id": 1912}, {"id": 1913}, {"id": 1914}, {"id": 1915}, {"id": 1916}, {"id": 1917}, {"id": 1918}, {"id": 1919}, {"id": 1920}, {"id": 1921}, {"id": 1922}, {"id": 1923}, {"id": 1924}, {"id": 1925}, {"id": 1926}, {"id": 1927}, {"id": 1928}, {"id": 1929}, {"id": 1930}, {"id": 1931}, {"id": 1932}, {"id": 1933}, {"id": 1934}, {"id": 1935}, {"id": 1936}, {"id": 1937}, {"id": 1938}, {"id": 1939}, {"id": 1940}, {"id": 1941}, {"id": 1942}, {"id": 1943}, {"id": 1944}, {"id": 1945}, {"id": 1946}, {"id": 1947}, {"id": 1948}, {"id": 1949}, {"id": 1950}, {"id": 1951}, {"id": 1952}, {"id": 1953}, {"id": 1954}, {"id": 1955}, {"id": 1956}, {"id": 1957}, {"id": 1958}, {"id": 1959}, {"id": 1960}, {"id": 1961}, {"id": 1962}, {"id": 1963}, {"id": 1964}, {"id": 1965}, {"id": 1966}, {"id": 1967}, {"id": 1968}, {"id": 1969}, {"id": 1970}, {"id": 1971}, {"id": 1972}, {"id": 1973}, {"id": 1974}, {"id": 1975}, {"id": 1976}, {"id": 1977}, {"id": 1978}, {"id": 1979}, {"id": 1980}, {"id": 1981}, {"id": 1982}, {"id": 1983}, {"id": 1984}, {"id": 1985}, {"id": 1986}, {"id": 1987}, {"id": 1988}, {"id": 1989}, {"id": 1990}, {"id": 1991}, {"id": 1992}, {"id": 1993}, {"id": 1994}, {"id": 1995}, {"id": 1996}, {"id": 1997}, {"id": 1998}, {"id": 1999}, {"id": 2000}, {"id": 2001}, {"id": 2002}, {"id": 2003}, {"id": 2004}, {"id": 2005}, {"id": 2006}, {"id": 2007}, {"id": 2008}, {"id": 2009}, {"id": 2010}, {"id": 2011}, {"id": 2012}, {"id": 2013}, {"id": 2014}, {"id": 2015}, {"id": 2016}, {"id": 2017}, {"id": 2018}, {"id": 2019}, {"id": 2020}, {"id": 2021}, {"id": 2022}]}, "entities": {"values": [{"id": 355, "name": "World", "code": "OWID_WRL"}]}}, "origins": [{"id": 9504, "title": "Historical Statistics for Mineral and Material Commodities", "description": "Information on mineral commodities, including production and unit value (the real and nominal price in U.S. dollars of a metric ton of apparent consumption).
