Brazil Production of lignite coal, 1949-2020 -

2020-12-23  In 2018, production of lignite coal for Brazil was 1,596 thousand short tons. Though Brazil production of lignite coal fluctuated substantially in recent years, it tended to increase through 1999 - 2018 period ending at 1,596 thousand short tons in 2018. Lignite is the lowest rank of coal, often referred to as brown coal, used almost exclusively as fuel for steam-electric power generation.
