Relationship between Los Angeles abrasion value and mineral content of metamorphic rocks

Dayarathna, IWTP; Puswewala, UGA; Abeysinghe, AMKB; Rohitha, LPS [Conference Full-text]

This research includes study of the relationship between Los Angeles Abrasion Value and the mineral content of rock aggregates narrowed down to the commonly found high grade metamorphic rocks in Sabaragamuwa Province. Los ...
Applicability of pre-heating techniques for recovery of garnet from garnet biotite gneiss

Jayakodi, JDSU; Weliwita, BY; Nishanthan, SS; Samaradivakara, GVI; Abeysinghe, AMKB; Rohitha, LPS; Vijitha, AVP [Conference-Full-text]

In mineral processing industry, the highest energy is consumed by crushing and grinding operations. However, if we can initiate micro cracks in the hard rock pieces in advance, we should be able to reduce the crushing ...
Dynamics of the Madu-Ganga Estuary

De Silva, UHNH; Somasiri, RBHP; Jayasekara, NNL; Ratnayake, AS; Dushyantha, N; Weththasinghe, SM; Samaradivakara, GVI; Vijitha, AVP; Ratnayake, NP [Conference Full-text]

Among the estuaries in Sri Lanka, Madu-Ganga Estuary plays a significant role to generate a massive income through tourism. The existing tropical ecosystem attracts the tourists. However, this ecosystem faces problems of ...
Nearshore sediment dynamics in Sri Lanka

Ratnayake, AS; Weththasinghe, SM; Dushyantha, N; Premasiri, HMR; Ratnayake, NP [Conference Full-text]

Coastal environment is a unique morphodynamic system for diverse changes. The present study estimated coastal morphodynamic changes and sediment transportation directions at locations of Uswetakeiyawa beach nourishment ...

Fluctuations in groundwater level and corresponding earth resistivity changes

Chandrasena, RTPIU; Madushanka, GHSP; Amalan, K; Samaradivakara, GVI; Chaminda, SP; Jayawardena, CL [Conference Full-text]

The earth resistivity at a known location was frequently measured, through resistivity sounding. Resistivity of subsurface layers could be influenced by the permeability, porosity, transmissivity, composition etc., where ...
Effect of organic bio-polymer on bio-mineralization of CaCO3

Nawarathna, THK; Nakashima, K; Kawasaki, S [Conference Full-text]

Organic matrix in the biogenic CaCO3 has a significant influence on the CaCO3 crystal growth, its polymorphs and morphology. In this research, effect of the cationic and anionic organic bio-polymers on the crystallization ...
Diamond core drilling for narrow vein graphite exploration - as practiced at Bogala Mines, Sri Lanka (A Case Study)

Ekanayake, EMKB [Conference Full-text]

The vein type graphite deposits which are rich in carbon found in Sri Lanka occur in metamorphic rocks as narrow steeply dipping veins. In Sri Lanka, generally these graphite deposits are explored by diamond core drilling ...
Optimizing the specific charge for limestone blasting at Aruwakkalu Limestone Quarry

Perera, WDS; Epa NBM; Neligama, DA; Hemalal, PVA; Dharmaratne, PGR [Conference Full-text]

The objective of this research is aimed at optimizing the specific charge for limestone blasting at Aruwakkalu limestone quarry without leading to poor fragmentation of the blasted material. Thus, in reducing costs incurred ...
Effects of metal ions on flotation of Sulfide minerals

Mayumi, I; Atsuhiro, T; Tatsuya, S; Tsuyoshi, H; Carlito, BT; Naoki, H [Conference Full-text]
