the application of lanscientific handheld ore analyzer in the detection of uranium and thorium
2021-08-18 | industry: 

in nature, uranium is usually found in the form of u-238 (99.2739 – 99.2752%), u-235 (0.7198 – 0.7202%), and a small part of it is found in the form of u-234 (0.0050 – 0.0059%). a major feature of u-235 is the isotope that can naturally fission (can maintain a chain reaction of nuclear fission). u-238 is derived from rapid neutron fission. uranium ore can be mined by the following methods: open-pit veins, underground, in-situ leaching, and underground mining (using high-pressure water jets). low-grade uranium ore usually


contains 0.01 to 0.25% uranium oxide (usually called u 3 o 8 by us). in nature, uranium occurs in several types of deposits, including unconformity deposits, olympic dam deposits, sandstone deposits, quartz- pebble conglomerate deposits, surface veins (calcite conglomerate veins), vein-type deposits, volcanic and volcanic vent-related deposits, intrusive deposits, and metasomatic rock deposits.


thorium is a natural radioactive element that undergoes alpha decay. it is estimated that the content of thorium in the earth's crust is about three to four times more than that of uranium (9.6 ppm thorium, 2.7 ppm uranium), and it is mainly refined as a by-product of monazite sand extraction of rare earth metals.

on-site portable xrf technology has the ability to provide fast and accurate test results with little or no sample preparation. it can be applied to all stages of mining activities, from basic exploration and mining, ore grade control, and even to the environment investigation.


the truex series of handheld ore analyzers from lanscientific instruments brings huge improvements to the detection limit, accuracy and collection time in terms of on-site testing. these benefits come from the revolutionary technological changes of lanscientific instruments. when our handheld analyzer is used in conjunction with the test stand, it can be used in the laboratory to test the prepared samples
