Based on information from the Public Relations Team of the Geological Agency of the Ministry of Energy and Mineral Resources (ESDM), one of the rare ingredients in the Lapindo mud is minerals that are included in the Critical Mineral (CRM) category, namely Lithium (Li) and Strontium (Sr).
In addition, the location of the Lapindo mudflow can also be used for raw materials for pottery, ceramic bodies, bricks, and roof tiles.
“The lithium content in the Lapindo mud has levels of 99.26-280.46 ppm, and strontium levels of 255.44 – 650.49 ppm. Economical Mineral Potential is still in the general investigation stage so the data is not accurate because in general it is still using the results of the investigation stage. initial details that have not been detailed and are limited to shallow depths,” wrote the official statement from the Geological Agency’s Public Relations Team, quoted on Sunday (1/23/2022).
Investigations related to the ‘treasure’ in the Lapindo mud have been carried out by the Geological Agency of the Ministry of Energy and Mineral Resources since 2020. Then, in 2021 the Geological Agency began to examine in detail the findings of super rare minerals there.
The results of the initial investigation of the Lapindo mud content will be the basis for consideration in determining the target area for further potential investigations. Later, the study of the characterization and extraction of lithium and strontium in the Lapindo mud will be carried out by the Research and Development Center for Mineral and Coal Technology (Puslitbang tekMIRA), a work unit under the Ministry of Energy and Mineral Resources.
“From the results of the Lab analysis, LTJ levels are quite low, with the highest levels in the element Cerium (Ce). In addition to economic considerations, namely the use of Sidoarjo Mud as an economic mineral potential, mud handling/management is also to minimize the risk of its existence (hazard to resources),” he said. .
The discovery of lithium and strontium at the Lapindo mud location only came from a certain area. The area that became the source of this finding has a depth of 5 meters. It is not impossible, further findings related to the ‘treasure’ under the Lapindo mud will increase in the future.
“More detailed research needs to be done to get more detailed and definite data related to the amount of Lithium and Stronsium resources on the Sidoarjo mud content,” he said.
As is known, rare earth metals function as energy raw materials in the manufacture of batteries in this case can be used as raw materials for electric vehicle batteries. In fact, rare earth minerals can also be used as raw materials for nuclear power plants (NPP).
Based on survey data from the Geological Agency of the Ministry of Energy and Mineral Resources 2009 – 2020, rare earth metals are found in Tapanuli, North Sumatra about 20,000 tons. Then, in Bangka Belitung there is monazite mineral containing rare earth metals, and this monazite was found with tin deposits with a resource of around 186,000 tons.
Then, in Kalimantan, there was a study in West Kalimantan on the potential of rare earth metals in the form of laterite 219 tons and Sulawesi 443 tons. The Ministry of Energy and Mineral Resources opens investment opportunities to work on the exploration of these rare earth metals, especially in the technology sector to process exploration acquisitions.
