Mining in Paraná
State in Southern Brazil / From Wikipedia, the free encyclopedia
Mining in Paraná is a set of studies, research, knowledge, and theories regarding the mineralogical aspects of the state of Paraná, in Brazil. Paraná is the second federative unit of Brazil that produces the most talc, which is extracted in the municipality of Ponta Grossa. In 2016, it was responsible for 40% of the country's production, ahead of Bahia and São Paulo.[1] It is the sixth state that produces the most silver, behind Mato Grosso.[1] Coal, dolomite (used to produce metallic magnesium and refractory marble), limestone ( used in the steel and metallurgical industries, and to produce cement and paints) are also found in Paraná. Shale (schist) is also extracted, which, when heated, provides natural gas, sulfur, and other fuels. Petrobrás developed a shale industrialization program, which includes a plant in São Mateus do Sul, in the south of the state.[2][3][4]
