The 674 quilombolas or Maroons families living in municipality of Moju are suffering the negative impacts of the kaolin transport by Vale. The kaolin is explored by CADAM, a subsidiary of Vale, in Vitoria do Jari and transported by a pipeline to Barcarena, both in the State of Para. According to the report of the Ministerio Publico Federal in Para, since November 2006 six quilombolas communities (Jacundai, Mirindeua, Conceicao de Nossa Senhora das Gras, Santa Luzia, Sao Bernardino and Sao Manuel) had their crops affected by the mining company.
In December 2006, the quilombolas blocked three access roads used by Vale to reach the mining site, in the lands of the quilombo Santa Maria de Tracuateau. The reason for the protest was the lack of compliance by the mining company in accordance with the municipality of Moju, in which it was established that the company would build a Community House for agricultural education and a health post for communities, as well as the recovery of 33 miles of road that cut the quilombo lands and reform of two bridges, which were damaged by mining trucks. At the same time, the Ministerio Publico Estadual has given support for the communities claim to carry out an environmental impact study to assess the activities of the company in the region.
In Moju there is also a large social tension because of the lack of land titles of quilombo lands. Part of the works of the Vale, especially the construction of a new pipeline of kaolin, was being built on the areas of this traditional population. Local media reported conflicts between quilombolas and the Vale, caused by failure to comply with the agreement signed between the mining company and the municipality, as a form of compensation for environmental damage caused to the quilombolas. The quilombolas has already denounced the deforestation of Brazilian nuts trees, the invasion of plantations and purchase of subscriptions to permission of entry of third-party companies in quilombolas lands. In November 2007, towers of power transmission lines constructed by Vale in quilombola lands were destroyed, and the road that connects the construction site of the pipeline and the company was blocked. An agreement with Vale was signed, where it was established that the company would pay for a study of environmental impacts in areas where Maroons live and would rehabilitate families affected by mining works.
In 2011, the Federal Court in Belém (PA) condemned VALE to pay monthly damages to families affected. In 2012, Vale sold the CADAM to KaMin by thirty million dollars.(See less)
