Field investigations suggested the occurrence of heavy minerals as beach-placers, and inland/raised beach deposits along the coastline of Sri Lanka. Geochemical results showed the enrichment of TiO 2, Fe 2 O 3, Al 2 O 3, and trace elements, and depletion of other major oxides such as Na 2 O, K 2 O, MnO, MgO, CaO, and P 2 O 5 .

The beach sediment from this region, exhibited elevated concentrations of major elements like silicon (Si) and manganese (Mn) and high abundance of minor and …

The southeastern coast of Sri Lanka contains extensive depositional beaches, lagoons, and estuaries, and shows signs for occurrences ... [Show full abstract] of valuable mineral placers. We ...

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 ...

Mineral detection using remote sensing techniques is important since it saves the time and effort of carrying out manual land surveys. In this paper a novel algorithm, which can be used to detect ilmenite using hyperspectral image analysis is discussed. To investigate this task, a hyperspectral image obtained from the Earth …

The sand deposited by the tsunami is light colored and overlies a pre-tsunami darker sandy soil.2.1.1 Lanka Mineral Sands Limited (LMSL) formerly Ceylon Mineral Sands Corporation was established in 1957 for the exploration of beach sands in Sri Lanka subsequently converted to a fully Government-owned Company in 1992 under the …

exploited since 1957 (Herath 1980 ; Lanka Mineral Sand Ltd 1999). The Pulmoddai deposit contains 6 million tons of heavy mineral sands (Sri Lanka Minerals Year Book 2014). The Verugal deposit is located about 50 km south of Trin-comalee Bay (Fig. 1). This deposit extends over a distance of more than 3 km (Fernando 1986), and no commercial

Pulmoddai mineral sand deposit which extends about 800,000 m 2 is located in the northeast coastal zone in Sri Lanka. It is the largest and well known heavy mineral sand …

The current status of the heavy mineral industry and its perspectives are poorly examined in Sri Lanka. Therefore, this paper presents and assesses the heavy mineral industry of Sri Lanka related to ilmenite, rutile, and zircon using real-time data, obtained from Lanka Mineral Sands Limited (LMSL), during the last decade.

The main REE bearing minerals in the beach placers of Sri Lanka are monazite and xenotime. The heavy mineral prospects of the north-eastern coast of Sri …

The beach sands along the coasts of India contain large reserves of strategic minerals like ilmenite, monazite, zircon, etc. Monazite mineral is primarily used as an ore for extracting rare earths particularly cerium and lanthanum. In the present study, the chemistry and distribution of monazite found in the beach sands of …

Abstract. Southeastern landmass of Sri Lanka is laid on the Vijayan Complex (VC) rocks, a Precambrian basement characterized with specific geological features …

This confirms the onset of large-scale mineral sand mining in Mannar. According to the plan, Titanium Sands aims to drill 300 holes within an area of 3,600 square meters on the island of Mannar by the first week of March. 38 holes have already been placed of which 33 holes have a surface area of 2 meters and a depth of 12 meters.

Depletion of inland sand reserves for the construction industry and occurrence of beach sand deposits rich with heavy minerals such as ilmenite, rutile, garnet, zircon and monazite around the ...

The heavy mineral prospects of the north-eastern coast of Sri Lanka are high, with a heavy mineral content of about 70e85% in the Pulmoddai deposit and 45e50% in the Verugal deposit (Amalan et al ...

Heavy minerals have become an essential commodity in modern-day technology. The objective of this study is to examine the current status of the heavy mineral industry of Sri Lanka. The present study also examines the economic viability of potential heavy mineral placer deposits, based on geochemical data. Field investigations …

The results of the mineralogical and chemical analysis tests for the beach sand deposit indicated that 71% of beach sand was smaller than 355 µm in particle size and more than 99% of titanium ...

Placers are mineral deposits formed by the mechanical concentration of minerals from weathered debris. Placers can be classified as eluvial, alluvial, eolian, beach, and fossil (paleo) deposit types. Monazite-bearing placer-type deposits can occur in residual weathering zones, beaches, rivers and streams, dunes, and offshore areas.

This is the only commercially exploited mineral sands deposit in Sri Lanka while several other mineral sand deposits are available as beach mineral sand deposits. Some of them are along the beach north of Trincomalee (Nayaru & Nilaveli), Induruwa …

The main REE bearing minerals in the beach placers of Sri Lanka are monazite and xenotime. The heavy mineral prospects of the north-eastern coast of Sri Lanka are high, with a heavy mineral content of about 70%–85% in the Pulmoddai deposit and 45%–50% in the Verugal deposit (Amalan et al., 2018).

Beach-rocks are cemented coastal sediments that occur mainly under subtropical to tropical climatic conditions. Due to higher biogenic chemical association on the beach fronts, Sri Lanka comprises ...

2018). In 2015, Sri Lanka exported nearly 39,000 tonnes of ilmenite, 1,800 tonnes of rutile, and 600 tonnes of zir-con (Lanka Mineral Sands Ltd 2018; Subasinghe et al. 2021). Two heavy mineral deposits are located towards the north (i.e., Nilaveli to Mulativu beach placer deposits) and south (i.e., Verugal deposit) of the Trincomalee Bay (Fig ...
