Ceramext™ technology has developed a newly patented hot-forging processes that can repurpose mine tailings and other waste materials into advanced impermeable high strength patented ceramic compositions. Many new patented ceramic compositions are derived from waste materials including reservoir sediments, mine tailings, quarry fines, biomass ash, garbage incinerator ash, and coal fly ash. These waste materials, without using binders, can produce high quality floor, wall and roof tiles, building cladding, bricks, pavers, and other ceramic products suitable for marketing at competitive prices.
Climate change and increased populations have made it challenging to maintain some reservoir water capacities due to the need for sediment removal and lack of disposal sites. In California, more than 100 reservoirs can no longer be dredged due to mercury contamination in mine tailings exacerbated by dredging. The fine sands and silts from the sediments, whether dredged or dry mined when the reservoir is periodically drained, can be turned into patented high quality ceramics using Ceramext™ technologies. At the temperatures necessary for Ceramext production, mercury is volatile and can be safely recovered in the kiln flues using activated carbon filters in the vapor phase.
