The mineral resource potential of an area is a measure of the likelihood within forescale. It was against this background that the mineral compositions in rocks of Hong Local Government Area were investigated. The un-weathered rock sample was chiseled, dried for 12 hours and pulverized. X-ray fluorescence spectrometer (XRF) was used for the mineral oxides determination. Considerable amounts of SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2 and MnO were recorded in the 10 locations. The mean values of SiO2 contents were comparably higher (72.51 %) among the locations. The mineral oxides revealed in the study have potentials for industries.

Abstract
Using a highly detailed dataset at the municipality level, drawn from the Spanish Mining Cadastre of 1890, this paper shows how the mining sector affected education provision and human capital formation in early twentieth century Spain. The results indicate that there were two patterns in mining towns. Those mines that invested in technology, those highly productive, and those with post-extraction industries linkages were able to transform mineral capital into human capital. However, in areas where mines were characterized by unskilled labour and low living standard, the mining sector had a negative impact on education, especially in women's human capital formation.

Abstract
The green transition is creating exponential needs for critical minerals. As demand currently exceeds supply for many of these minerals, governments worldwide are devising strategies to secure stable procurements of the minerals they lack as well as to ensure that they reap the benefits of their own natural wealth. The European Union (EU) is in a difficult position in this regard due to limited domestic reserves and, thus, serves as an ideal case study to explore developments in international economic law on this issue. Internally, the EU has been reforming its financing mechanisms, developing risk management tools, and enhancing recycling. Externally, the EU has been using international trade tools to focus on access to supply rather than traditional market access issues while also developing new investment rules to open doors and protect its foreign investors in extractive industries. Both internal and external actions are being coordinated with allies through new cooperative mechanisms. However, challenges abound. These strategies will face resistance from resource-abundant economies in view of their growing demand for policy space to protect their own mineral sector. Such strategies are also inherently competitive and, hence, might lead to growing tensions among resource-seeking economies themselves.

Der ökonomische und soziale Strukturwandel der Industriegesellschaft findet seine kulturellen Entsprechungen in der post-industriellen "Landschaftsreparatur" und in der "Musealisierung" industrieller Hinterlassenschaft. Strategien der In-Wert-Setzung des industriekulturellen Erbes ließen neue Orte und Landschaften der Erinnerung entstehen, die zentrale Ankerpunkte regionaler, post-industrieller Identitäten sind. Dabei erscheint das Argument des Authentischen essentiell für die In-Wert-Setzungs-Prozesse des industriekulturellen Erbes. Aus unterschiedlichen Perspektiven thematisieren die Beiträge des Bandes diese Zusammenhänge. Sie historisieren zugleich die industriekulturelle Authentizität

ABSTRAKKonservasi mineral dan batubara merupakan salah satu aspek yang diamanatkan oleh Undang-Undang Minerba untuk mewujudkan kaidah teknik pertambangan yang baik (Good Mining Practice). Konservasi minerba adalah upaya dalam rangka optimalisasi pengelolaan atau pemanfaatan sumber daya mineral dan batubara secara terukur, efisien, bertanggung jawab, dan berkelanjutan. Objek-objek yang menjadi target pengelolaan pelaksanaan konservasi mineral dan batubara sesuai Lampiran VII Kepmen ESDM No. 1827 K/30/MEM/2018 meliputi recovery penambangan, recovery pengolahan, batubara kualitas rendah, mineral kadar rendah, mineral Ikutan, sisa hasil pengolahan dan pemurnian, serta cadangan marginal. Kegiatan pertambangan timah di Indonesia berada di wilayah Provinsi Kepulauan Bangka Belitung dan Kepulauan Riau. Kegiatan ini dimulai sejak era kolonial Belanda yang ditandai dengan berdirinya "Banka Tin Winning Bedrijf" (BTW) di Belitung dan Singkep. Penambangan dilakukan oleh perusahaan swasta Belanda yaitu "Gemeeenschappelijke Mijnbouw Maatschappij Biliton" (GMB) dan "NV Singkep Tin Exploitatie Maatschappij" (NV SITEM). Kedua perusahaan ini berubah nama menjadi PT Timah, Tbk. Kegiatan pertambangan timah nasional mengalami pasang surut seiring dengan menipisnya cadangan timah karena eksploitasi yang sudah berlangsung lama dan perubahan terhadap kebutuhan saat ini maupun masa depan timah di dunia perindustrian. Untuk menjaga keberlanjutan kegiatan penambangannya, PT Timah, Tbk melakukan berbagai inisiatif diantaranya pelaksanaan konservasi dengan mengoptimalkan cadangan marginal, pemanfaatan sisa hasil pengolahan, penambangan mineral kadar rendah dan mineral ikutan. Saat ini PT Timah, Tbk mulai melakukan inventarisasi kembali cadangan timah yang sebelumnya ditinggalkan dan melakukan estimasi ulang untuk dikategorikan sebagai cadangan marginal. Potensi tambahan cadangan timah ini berasal dari bekas penambangan yang tidak tuntas maupun dari bekas penambangan tanpa ijin. Selain itu, PT. Timah, Tbk juga melakukan pendataan, inisiatif pengelolaan, dan rencana pemanfaatan untuk sisa hasil pengolahan, mineral kadar rendah dan mineral ikutan dengan aplikasi ketersedian teknologi saat ini. Beberapa upaya yang terus dikembangkan untuk tetap menjaga keberlanjutan industri pertambangan timah dan pengembangan timah primer adalah dengan pengembangan metode penambangan baru seperti borehole mining (BHM) dan inovasi metode penambangan yang sudah ada seperti cutter section dredges (CSD). Pelaksanaan hal-hal tersebut diatas adalah upaya nyata yang dilakukan oleh PT Timah, Tbk untuk melaksanakan konservasi mineral dan mendorong terwujudnya kaidah teknik pertambangan yang baik. Dengan pelaksanaan konservasi mineral dan dukungan dari seluruh stackholder, baik Pemerintah Daerah Provinsi Kepulauan Bangka Belitung dan PT. Timah, Tbk maka diproyeksikan kegiatan pertambangan timah nasional dapat terus bertahan dan berkelanjutan untuk menunjang industri timah nasional.Kata Kunci: konservasi minerba, timah, cadangan marginal, sisa hasil pengolahan, mineral kadar rendah, mineral ikutan, pengelolaanABSTRACTMineral and coal conservation is one of the aspects mandated by the Minerba Regulation to embodies the principles of Good Mining Practice. Mineral and coal conservation is an effort to optimize the management or utilization of mineral and coal resources in a measured, efficient, responsible and sustainable. Objects that are targeted for mineral and coal conservation in accordance with Attachment VII of the Minister of Energy and Mineral Resources Decree No. 1827 K / 30 / MEM / 2018 comprise of restoration mining recovery, processing recovery, low quality coal, low grade minerals, gangue minerals, residues from processing and refining, and marginal reserves. Tin mining activities in Indonesia are mainly in the provinces of the Bangka Belitung Islands and Riau Islands. This activity began in the Dutch colonial era marked by the establishment of "Banka Tin Winning Bedrijf" (BTW) in Belitung and Singkep. Mining is carried out by a Dutch private company, "Gemeeenschappelijke Mijnbouw Maatschappij Biliton" (GMB) and "NV Singkep Tin Exploitatie Maatschappij" (NV SITEM). These two companies then merged into PT Timah, Tbk. Tin mining activities in Indonesia experienced the ups and downs through the depletion of tin reserve due to lifelong exploitation and changes in the current needs and the future of tin in the industrial world. To ensure the sustainability of its mining activities, PT Timah, Tbk has conducted a variety of initiatives such as conserving by optimizing marginal reserve, utilizing the residue of processed products, mining low grade minerals and accompanying gangue minerals. Currently PT Timah, Tbk starts to carry out an inventory of the previously abandoned reserves and re-estimates to be categorized as marginal reserves. This potential additional on tin reserves are comes from mines that are incomplete or from ex-mining activity without permits. In addition, PT. Timah, Tbk also conducts data collection, management innitative, and utilization plans for processing residues, low grade minerals and gangue minerals with current technology applications available. Some efforts that are continually being developed for the sustainable development of the tin mining industry and primary tin development are by developing new mining methods such as borehole mining (BHM) and innovate in existing mining methods such as cutter section dredges (CSD). The implementation of the above is a real effort made by PT Timah, Tbk to carry out mineral conservation and encourage the realization of good mining practice. With mineral conservation and the support from the stockholders, the Bangka Belitung Islands Provincial Government and PT. Timah, Tbk, it is projected that tin mining activities in Indonesia can be maintained and sustainable to support the national tin industry.Key Word: Coal and mineral Conservation minerba, tin, marginal reserve, residual of processing and refining, Low grade mineral, gangue mineral,management

This book analyses institutional development that the Peruvian state has undergone in recent years within a context of rapid extractive industry expansion. It addresses the most important institutional state transformations produced directly by natural resources growth. This includes the construction of a redistributive law with the mining canon; the creation of a research canon for public universities; the development of new institutions for environmental regulation; the legitimation of state involvement in the function of prevention and management of conflicts; and the institutionalization and dissemination of practices of participation and local consultation.--
