  • Design and fabrication of cable bolt for excavation in a fractured rock 
    Dhanawardana, YLC; Siriwardana, HDPM; Henderson, SH; Kumara, HMCP; Indika, KAS; Dharmaratne, PGR; Welideniya, HS; Rohitha, LPS [Conference-Abstract]
    In fractured rock masses, large excavations have an unsupported stand-up times Jess than the minimum time required to support the roof after the excavation. Therefore, the principal objective in the design of a support ...
  • Design of a low cost magnatic separator for local beach sand separation. 
    Boralugoda, BPD; Udowita, UGKBP; Sayathan, K; Rohitha, LPS [Conference-Full-text]
    Study had been carried out to identify beach sand minerals available locally. Principles, cost, and design feasibilities of industrially used magnetic separators were reviewed. As the best suit for requirements permanent ...
  • Finding a new sampling methods and studying its characteristic with respect to existing methods. 
    Kumarasinghe, KJMD; Nanayakara, SS; Yapa, YHPSM; Rohitha, LPS [Conference-Full-text]
    In mineral processing industry, quality of minerals has to be measured in several stages of processing. In measuring the quality, obtaining accurate samples is of prime importance in representing the bulk material. There ...
  • Identifying Garnet Bearing Rocks Suitable for Mining and Processing of Manufactured Garnet Sand 
    Senthuran, S; Boyagoda, EMRCL; Rukshan, AMM; Sathiyaparathan, T; Wannisinghe, WMVK; Weerawanakula, S; Premasiri, HMR; Rohitha, LPS; Abeysinghe, AMKB [Conference-Full-text]
    Garnet sand has a wide range of applications in mineral industry, mainly as an abrasive. The demand for garnet sand has been increasing rapidly during recent past. Industrial quality garnet can be recovered from beach sand ...
  • Parameters which affect the Flow Rate of Minerals through Silos with varying Silo angles and Particle Size 
    Kankanamge, LUM; Siriwardene, KM; Sairudeen, MI; Rangana, WGL; Chathurange, KJVM; Rohitha, LPS [Conference-Full-text]
    The study was carried out to develop a model for mineral flow rate through conical silos. Dominant factors governing the flow behaviour of minerals through silos were studied. Silo angle and the outlet diameter were ...
