mining mining quarrying: although seldom used to form entire structures, stone is greatly valued for its aesthetic appeal, durability, and ease of maintenance. the most popular types include granite, limestone, sandstone, marble, slate, gneiss, and serpentine. all natural stone used for structural support, curtain walls, veneer, floor tile, roofing, or strictly ornamental purposes is the production of aluminium involves three main stages: mining bauxite ore, refining bauxite to alumina and then smelting alumina to produce aluminium. bauxite comes from open mines mainly located in tropical and subtropical regions. On average it takes to tonnes of bauxite to produce tonnes of alumina, yielding tonne of aluminium.To effectively extract and process all the materials from the ground, the mining and quarrying industry must maximise different types of equipment. but given the complexity and difficulty of the activities in these industries, these pieces of equipment must only be controlled and used by those who have enough experience and have the licenses and certifications to handle their operations.
