RESUMO

This dissertation deal with a research on gold mining in Mato Grosso state, since its historical period in the Colonial times until the second Gold Cycle, which attained its climax in the 80 s. Besides geographical, social, economic and historical features of Mato Grosso state, the resumption of prospectors activities in the end 70 s followed by several mining companies searching for gold in the periodo 1979-1995 are outlined. The geological setting the mineralization types, the exploitation modes, the dressing units for the gold ore, the "garimpeiro" reserves established in the state, the production statistics are described in the major producing regions Cuiabá lowlands, Southwest region and Northen region. Although the gold production has shown a decrease caused by the depletion of secondary deposits and to the high mining costs, the potential value of primary mineralizations is encouraging several companies that invest in exploration, raising hopes that their production will overcome that based on artisanal work
