[Abstract] The Northeast of Brazil, essentially in the Borborema Province [1], have small-scale mining as a secular activity, promoting livelihood and economic development of cities with mining vocation [2][3]. Junco do Seridó is a town located in the Brazilian State of Paraiba, with privileged rich geology in pegmatite fesdspatic bodies with low iron levels, fastened in quartzites of the Equador Formation. The chemical weathering in acidic conditions [4] in the region promoted degradation of pegmatites, turning feldspars and other silicates in kaolinite with impurities of quartz, muscovite, iron oxides-hydroxides, tantalite and several clay minerals. The kaolin is drawn by hand, initially in open pit front. With the advancement of depth, the mining evolves underground, always handmade, rustic, dangerous, and unhealthy. The goal of this study is to show how the artisanal mining of kaolin influences livelihoods and promotes the economic development of the municipality, but on the other hand causes environmental impact and serious damage to the health of miners. The precariousness of working conditions associated with the lack of surveillance, mining planning of technological innovation, and the absence of recovery projects of degraded areas, altogether cause a mismatch between economic development, social welfare, occupational health, and environmental balance in small-scale mining.
