    Abinav, R; Chamara, HAKM; Dinojan, J; Sampath, HKT; Dissanayaka, DMDOK [Conference-Full-text]
    Sri Lanka is endowed with a variety of industrial minerals such as graphite, quartz, mica; brick and tile clay, ball clay, kaolin, dolomite, calcite, feldspar, miocene limestone, mineral sands (Ilmenite, Rutile , Garnet ...
  • The flow behavior of mineral particles through glass funnels 
    Rohitha, LPS; Dissanayaka, DMDOK; Fernando, WLW [Conference-Extended-Abstract]
    In industry the flow of mineral particles in silos playa very important role in the recovery of these particles into containers for bagging and transport. The silo design parameters and particulate properties are restricting ...
  • Flow Behavior Of Mineral Particles Through Silos 
    Rohitha, LPS; Dissanayaka, DMDOK; Fernando, WLW [Conference-Abstract]
    Flow behavior of dry minerals in silos has been investigated initially with glass funnels with different orifices. Thereafter, funnel was scaled up to a pilot plant (Silo) with adjustable orifices at its discharge end. The ...
  • Resource recovery from photographic waste by electro-winning 
    Wijeyekoon, SLJ; Rohitha, LPS; Fernando, WLW; Dissanayaka, DMDOK; Karunarathna, S [Conference-Abstract]
    Industries such as mining and industrial minerals, metallurgical, photographic, textile, leather and chemical produce wastewater containing heavy metals that are hazardous to man and the environment. Indiscriminate ...
  • Study on the suitability of cation selective membrane and the effect 011 current density for electrodialitic removal of heavy metal joils 
    Dissanayaka, DMDOK; Jaaweera, MW; Gunawardhana, WDDH; Wijekoon, SLJ [Conference-Extended-Abstract]
    Heavy metal pollution of the environment is a major environmental problem facing the modem world. Their persistence in the environment and the difficulty in removal from wastewaters make them available for aquatic and ...
