Resumo: The Seridó region, located in northeastern Brazil, in the states of Paraíba and Rio Grande do Norte, is known for its vast reserves of kaolin from pegmatites. Small companies mine and process ore. However, these operations are precarious, lacking mining planning and processing studies. Consequently, the recovery rates are only 25%, and mining accidents happen. Within a Ministry of Science and Technology work project named Associated Entities, the Centre for Mineral Technology and the Federal University of Campina Grande carried out integrated research, technology and innovation actions to add value to the mineral production chain in the Seridó region. After elaborating on a working plan, the partners collected information on the area, which they used to construct geological maps and computerized mine models. In addition, a kaolin processing plant with a hydrocyclone, aiming to increase the ore's recovery, was studied. This project results were two pit design scenarios with distinct geometric characteristics for the mine planning stage. The first scenario presented better results than the second, with a higher ore tonnage recovery and a lower waste/ore ratio. In the processing stage, the hydrocyclone tested plant led to a concentrate with high kaolinite percentages. The mining and processing project showed the possibility of extracting and processing the kaolin ore in a safer and more economically viable way for small producers.

Pequenas empresas fazem o processo de extração e beneficiamento do minério. No entanto, essas operações são precárias. A falta de planejamento na lavra e no processo de beneficiamento faz com que os pequenos produtores de caulim tenham apenas um aproveitamento de 25%, e diversos acidentes causados na etapa de extração. O projeto Entidades Associadas do Centro de Tecnologia Mineral – CETEM/MCTI, em parceria com a Universidade Federal de Campina Grande -  UFCG foi criado para desenvolver ações integradas de pesquisa, tecnologias e inovação para agregar valor à cadeia produtiva mineral na região do Seridó. Foi elaborado um plano de trabalho onde se fez o levantamento de informações da área. Foram coletados dados em campo e utilizados na elaboração de mapas e modelos geológicos para cálculo de cubagem, utilizando software computacional. Além disso, foi montada uma planta piloto de beneficiamento de caulim utilizando hidrociclone, visando o aumento de recuperação do mineral minério. Na etapa de planejamento de lavra foram elaborados dois cenários de lavra com características geométricas distintas. O primeiro cenário apresentou resultados melhores que o segundo. A tonelada de minério foi maior e a relação estéril minério menor. No processo de beneficiamento a recuperação de caulim apresentou bom resultado. O concentrado do processo apresentou altas porcentagens de caulinita. O projeto de lavra e beneficiamento mostrou a possibilidade de extrair e tratar um minério de forma mais segura e viável economicamente.Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte2023-12-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoapplication/pdfapplication/pdfhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/1579510.15628/holos.2023.15795HOLOS; v. 6 n. 39 (2023): v.6 (2023)1807-1600reponame:Holosinstname:Instituto Federal do Rio Grande do Norte (IFRN)instacron:IFRNporenghttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/15795/3906http://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/15795/3907Brasilhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMarvila de Almeida, KayroneWilson Hollanda VIdal, FranciscoFerreira Sousa, Antônio PedroFernández Castro, Nuria2023-12-29T23:54:16Zoai:holos.ifrn.edu.br:article/15795Revistahttp://www2.ifrn.edu.br/ojs/index.php/HOLOSPUBhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/oaiholos@ifrn.edu.br||jyp.leite@ifrn.edu.br||propi@ifrn.edu.br1807-16001518-1634opendoar:2023-12-29T23:54:16Holos - Instituto Federal do Rio Grande do Norte (IFRN)false
