New Route of Utilization of Pegmatites Tailings to Application as a Ceramics Raw Materials

Abstract

The proposal to obtain a new route for exploitation of tailings from pegmatite emerged from the need of many companies that showed to reuse of these tailings as raw materials ceramics. The pegmatites represent a large part of available industrial minerals. These can be classified into: kaolin, feldspar, mica, quartz and metallic minerals such as tantalite / columbite and others. The consumer markets for these minerals are glassmaking, ceramic industries, paper, pulp, metallurgy, etc. Order for the product is fit for sale ceramics and metals companies must be of high purity of this raw material. Therefore, the process of separation of these minerals must be carried out as effectively as possible. In this study, surveys have been made to the development of a new process route which facilitates, an optimized manner, separation from pegmatite, concentrated in the waste process of extracting companies, so that a better product shall be passed through the ceramic industry.
