Mineralogy and Geochemistry of beach sediments …
The beach faces of the SE coastline in Sri Lanka are mainly exposed as sandy beaches with siliciclastic sediments. Within 45 km of coastline, scatter distributions of heavy mineral rich fine sands occur near to each fluvial outlet.
Characterization of Beach Sand Deposits with Heavy
microscopic studies of beach sand is one of the most accurate methods in the determination of percentages of constituent heavy minerals of beach sand. However, in this study a magnetic survey method was tested as a field method to separate magnetic minerals from non-magnetic minerals in beach sand. The main
Analysis of Sediment Characteristics and Depositional …
Pulmoddai mineral sand deposit which extends about 800,000m 2 is located in the Northeast coastal zone of Sri Lanka. It is the largest and well known heavy mineral sand deposit in Sri Lanka. High-quality Zirconium-bearing minerals like Rutile, Zircon, and Ilmenite are concentrated in this deposit.

Pulmoddai beach sand deposit is the most important nonferrous mineral reserve in Sri Lanka, containing some of the most expensive and sought-after metals in the world.
Pulmoddai Mineral Sand Deposits
Pulmoddai is a town situated on the northeastern coast of Sri Lanka, close to Trincomalee. Pulmoddai lies between Trincomalee and Mullaitivu. It is famous for mineral sands that are mined at its beach. The Pulmoddai deposit is about 6 kilometers in length and about 100 meters in width.
Grain size distribution of modern beach sediments in Sri Lanka …
The objective of this study is to analyze grain size distributions of modern sandy beach sediments in Sri Lanka. Sediment samples (n = 90) were collected from beach berm, representing the entire coastline of Sri Lanka. Grain sizes were determined by …
Extraction of Rare Earths from Monazite in Pulmoddai …
Pulmoddai beach sand deposit is the major Monazite deposit in Sri Lanka. Although many researchers have developed several methodologies to extract REEs, Sri Lanka has not been able to develop a successful industrial-level methodology to extract REEs yet. Pulmuddai mineral sand contains Ilmenite, Garnet, Rutile, Zircon, Spinal, Sillimanite and ...
Which mineral is found abundantly in Sri Lanka?
Pulmoddai beach sand deposit is the most important non-ferrous mineral reserve in Sri Lanka to date. What are the most valuable resources in Sri Lanka? Natural resources include limestone, graphite, mineral sands, gems, and phosphate.
Geochemical, mineralogical and textural nature of beach …
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).
Mineral Resources Found in Sri Lanka
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.
