1992, the best offshore sand deposits in Sri Lanka are found between the coastal towns of Kalutara and Kalpitiya (Figs. 1 and 2). Furthermore, according to the GSMB the offshore sand deposits off the western coast have already been exploited by the government to provide material for the Colombo-Katunayake Highway
Aug 17, 2021 A best-known mineral sand deposit in Sri Lanka is situated at Pulmoddai to the north of Trincomalee. The major minerals found in this deposit are Ilmenite and Rutile. Other associated minerals are Zircon, Monazite, Garnet, Sillimanite, and few other heavy minerals.
The Recent Quaternary deposits in Sri Lanka include residual, alluvial, coral and shell formations, lagoons, estuaries, peat, gem-bearing gravels, and beach mineral sands (Fernando, 1986). ...
Deposits of Sri Lanka was compiled by the senior author on the basis of the study discussed in the text. Areas me categorized as highly probable, proba- ble, moderate, poor, and no deposits on the basis of their gem potential. An estimated 20% of Sri Lankas land mass contains viable gem

Beach sediments in Sri Lanka contain industrial-grade heavy mineral occurrencs. Samples of both offshore and onshore sediments were collected to examine the provenance, mineralogy and geochemical ...
Sri Lanka is well-endowed with industrial minerals including Graphite, Ilmenite, Rutile, Zircon, Quartz, Feldspar, Clay, Kaolin, Apatite (Phosphate Rock),Silica Sand, Garnet sand, Mica, Calcite and Dolomite. Pulmoddai beach sand deposit is the most important non-ferrous mineral reserve in Sri Lanka to date.
Sri Lanka could expand mineral sand mining geological survey . Nov 05, 2009 (LBO) - Sri Lanka has a chance to expand the mining of mineral sands deposits especially in the
Mar 08, 2014 Mar 08, 2014 In Sri Lanka, the total demand for sand is about 12,000,000 m 3 per year with a demand growth projected to increase by 10 % every year. However, Sri Lankas construction industry seems to face a shortage of sand if offshore sand mining is not promoted as a viable alternative and over-exploitation of river sand may lead to more significant damage to rivers (which is presently a serious issue).
Nov 02, 2018 Nov 02, 2018 Beach sediments in Sri Lanka contain industrial-grade heavy mineral occurrences. Samples of both offshore and onshore sediments were collected to examine the provenance, mineralogy and geochemical compositions of the heavy mineral occurrences. Coastal morphodynamic changes along the coastline of Sri Lanka were analyzed using the time-series satellite images. These

Well known Kaolin deposits in Sri Lanka are located at Boralasgamuwa and Metiyagoda.
Sri Lanka Could Expand Mineral Sand Mining. Nov 05, 2009 Sri Lanka has a chance to expand the mining of mineral sands deposits especially in the north east of the island with the end of a three decade war, the islands geological survey office has said.
Mineral deposits occur at the surface as well as at various depths of the earths crust. So far the mineral deposits discovered in Sri Lanka, except the Panirendawa iron ore deposit, are those which exposed to the surface. Hence it is necessary to investigate the subsurface to have a proper understanding
Monazite, apatite, allanite, and zircon are the primary rare earth (RE) minerals found in the preceding resources. The Pulmoddai mineral sand deposit is considered as the most potential REE ...
