COAL MINES & MINERALS
The Coal sector develops around the global use of coal as solid fuel for power stations and heating supply. USA is one of the major coal producers and users of the world. MATEC has installed over 50 filtration plants worldwide in the major coal mines. Rocks, coal and clay may contain a wide range of heavy materials, such as arsenic, lead, cadmium, chromium, iron, manganese, aluminum and nickel. This is why it is important filtrating waste waters to clarify them and recover the precious materials.
AGGREGATES SAND & GRAVEL
Aggregates generally include sand, gravel, expanded clay, vermiculite and perlite, and also any crushed material used in building construction. They can be found in composite materials, such as cement and bituminous conglomerates and plasters.
Sedimentary rocks: Chemical (Limestone, Dolostone, Evaporites), Clastic (Conglomerate, Breccia, Sandstone, Siltstone, Mudstone, Shale) Biologic (Coal, Chert); Igneous rocks: Intrusive (Gabbro, Diorite, Granodiorite, granite), Extrusive (Basalt, Andesite, Dacite, Rhyolite); Metamorphic rocks: Foliated (Slate, Schist, Gneiss), Non-foliated (Quartzite, Marble)
MARBLE & STONE CUTTING
In marble, granite and stone cutting and processing, water has multiple applications either in quarries or workshops or saw-mills. From cutting to polishing, water is necessary to avoid tools’ over-heating and reduce dust produced in various processes. Then, water needs to be treated in order to be re-used in the production closed cycle or discharged while complying with environmental regulations.
CONCRETE & TUNNELING
In the construction sector, the washing of trucks and mixers produces a slurry which contains several solids that could be recovered and sent back to the cement and concrete production process, cutting down costs. In addition, the water can also be recovered and reused or simply discharged. Thus clarify the washing water is an important point for saving it.
MATEC is able to offer complete plants in many other sectors, such as ceramics, glass, pharmaceutical and chemichal ones.
