This work shows the changes in properties of an industrial red-clay-based mixture, already in use in the production of floor tiles, due to additions of an ornamental stone cutting reject (marble and granite). Samples containing up to 30 wt.% reject were uniaxially pressed and sintered in air in an electric furnace (1100–1150 °C, for 2 h).

4.3.1: Surface Mining Methods. Surface mining methods are traditionally divided into two classes: mechanical and aqueous. Mechanical methods rely on breaking the ore by mechanical means, and aqueous methods rely on the use of water or another solvent, e.g. an acid, to break down the ore and facilitate its removal. Mechanical Methods Open pit …

Mining marble from a quarry involves creating a bench wall, which requires synthetic diamond wire and diamond-tipped drills to separate the rock to form a vertical plane. This involves drilling holes in the marble from the top of the quarry and lining up another drill hole from the side. The marble is fed through these holes and connected to …

Ground radiometric and magnetic methods are useful for follow-up surveys. A variety of geochemical (e.g. stream-sediment, soil, and till chemistry; 'direct indicator minerals') and biochemical methods have been successfully used, tested, or customised for exploration and detection of carbonatites and related deposits.

3.5.1 Granite and Marble. The commercial blocks of granite and marble obtained at the quarry are sent to the factory for processing operations. Most stone is sold as blocks, slabs, or finished products. The slabs are typically 2–3 cm thick in lengths of approximately 3 m and widths around 1 m, although any size is possible.

As a rule, marble and granite rejects show non-plastic behaviour and, like the great majority of traditional ceramic products, their major constituents, expressed as oxides, are silica (SiO 2) and alumina (Al 2 O 3 ), followed by lime (CaO) and alkaline oxides (Na 2 O, K 2 O). Iron oxide contents can be significant, due to the sawing process ...
