Processo de extração do minério de bauxita com base na malha de desmonte mecânico

Abstract

The strip mining method is widely used in bauxite mines, mainly due to the high productivity of the method and the ease of recomposition of the degraded area, in addition to being combined with other characteristics that favor the use of this method, one of them being the disposition of the ore body, which in the case of the Juruti Mine, the bauxite body is in tabular format, of low depth, which justifies the use of the method. For bauxite extraction to take place, some steps are necessary, among them: vegetation suppression; stripping, where this stage also includes the removal of laterite; the disassemble; mining and transportation of the ore and finally, the recomposition of the plowed land. The intention of the work was to demonstrate the bauxite extraction process, based on the mechanical disassemble mesh and to give the idea that if the opening of the disassemble mesh varies according to the type of bauxite in the mine, the quality of the disassemble can improve , mainly in the generation of blocks of ore with adequate sizes for the crusher, facilitating its loading and transport, and who knows how to improve its processing at the plant.
