Barite: Extraction
How a heavy mineral is sorted and ground
What this tab covers How it is mined, drilled or grown, and processed into a tradeable form: the main methods compared, their unit economics, by-products, and the companies that do this work globally and in India.Barite is barium sulfate, prized for its weight. It occurs in bedded sedimentary deposits and in veins, often with fluorite or lead-zinc ores. Most is mined in open pits, then upgraded by washing, jigging or flotation and ground to a fine powder. The drilling industry's standard requires a high specific gravity. Because high-grade 4.2 material was dwindling, the American Petroleum Institute added a 4.1 specification in 2010. Barite is a primary product. Only about 5% of supply is a by-product of other mining.
Barite is a primary industrial mineral, mined mainly for its weight. Most comes from shallow open pits worked with simple equipment and hand-sorting, which keeps costs low in India, China and Morocco. The key quality test is specific gravity: drillers want 4.2 (or 4.1 since 2010), and the high-grade deposits that meet it are becoming scarcer. Lower-grade ore can be upgraded by jigging or flotation. White, high-purity grades for paints and chemicals command higher prices.
Methods compared
| Method | Share of supply | Typical scale | Recovery / efficiency | By-products | Unit cost |
|---|---|---|---|---|---|
| Open-pit mining with hand-sorting and jigging (India, China, Morocco) | India 3.0 Mt, China 2.2 Mt, Morocco 1.0 Mt of about 8.7 Mt in 2025 (USGS, excluding US) | APMDC produced about 90% of India's 0.91 Mt in 2014-15 (IBM 2015) | n/a | None significant | Average value of Indian production about Rs 2,957/t in 2014-15 (IBM; value, not cost) |

| Grinding and blending to API drilling grade | US grinders sold 2.3 Mt in 2025 from domestic and imported ore (USGS) | grinders in nine US states (USGS 2026) | n/a | n/a | n/a |

How each method works
Open-pit mining with hand-sorting and jigging (India, China, Morocco)Benches are drilled and blasted, and lumps are sorted by hand or jigged to remove waste rock. Mangampet in Andhra Pradesh, run by the state-owned APMDC, is the main Indian example; most Indian output is 'off-colour' drilling grade. Lump is trucked to ports for bulk export or to local grinders.
Very low cost and fast to scale; quality depends on high-grade ore that is being depleted.
USGS MCS 2026; IBM Indian Minerals Yearbook 2015 Mining with flotation of lower-grade ore (US Nevada, others)Lower-grade or finely intergrown ore is ground and floated to raise BaSO4 content and specific gravity to API standards. Three US companies mined at four Nevada operations in 2025 and ground most of it in Nevada for western US drilling.
Uses deposits that cannot meet spec by sorting alone; higher energy and reagent costs.
USGS MCS 2026 Grinding and blending to API drilling gradeImported or domestic crude lump is dried and ball- or Raymond-milled to fine powder, blended to meet API 4.2 or 4.1 specific gravity, and bagged or bulk-shipped to rigs. Grinders sit near drilling regions because ocean freight is cheaper than long rail hauls (USGS).
Adds value close to customers; margins depend on rig activity.
USGS MCS 2026 By-product barite from other miningSome barite is recovered from fluorspar or lead-zinc tailings by flotation. The EU rates barite's companionality as low, meaning it is mostly a primary product.
Uses waste; small volumes.

About 5% of primary supply comes as a by-product (Nassar, Graedel & Harper 2015, approximate).Who does it: global

Who does it: India
| Company | Country | Activity | Volume | Year | Source |
|---|---|---|---|---|---|
| Andhra Pradesh Mineral Development Corporation (APMDC), Mangampet Recent annual volume not published; APMDC has raised nearly Rs 10,000 crore of bonds backed by barite revenues. | India | open-pit mining and export | 0.82 Mt (public-sector output, about 90% of India's total) | FY2015 | IBM Indian Minerals Yearbook 2015 (latest public company-level figure found); Mangampet reserves fell from 49 Mt (2015) to under 23 Mt (2024) per C-DEP (Indian Chemical News, Dec 2025) |
India was the world's largest barite producer in 2025 (3.0 Mt, USGS) and the largest exporter (22.6% of world export value in 2024), mostly from APMDC's Mangampet mine, which holds about 95% of India's barite. A December 2025 C-DEP report warned of under 10 years of accessible reserves and urged a strategic reserve. Barite is not on India's 2023 critical list.
