Abstract
Magnesium karbonat merupakan salah satu mineral magnesium berbasis karbonat, dengan nama mineral hydromagnesite. Aplikasi material magnesium karbonat digunakan untuk pemutih kertas, industri otomotif dan bahan kosmetik. Indonesia sebagai negara kepulauan memiliki sumber daya berbasis magnesium yang dapat digunakan sebagai bahan baku pembuatan magnesium karbonat seperti dolomit, magnesite, limbah garam (bittern) dan limbah pengolahan brine water geothermal. Limbah pengolahan brine water Gunung Panjang Bogor memiliki berbagai macam senyawa karbonat golongan II seperti magnesium karbonat, kalsium karbonat dan stronsium karbonat. Pada penelitian ini akan dilakukan proses ekstraksi magnesium karbonat dari limbah pengolahan litium berupa padatan yang mengandung magnesium karbonat, kalsium karbonat dan stronsium karbonat. Pada penelitian ini proses yang digunakan adalah proses kalsinasi magnesium karbonat secara parsial pada temperatur 600°C-700°C. Variabel penelitian pada proses kalsinasi parsial yaitu variasi temperatur kalsinasi (650, 675, 700 dan 750°C) dan waktu kalsinasi (2, 4 dan 6 jam). Setelah dilakukan kalsinasi akan dilakukan proses lanjutan yaitu slaking, karbonatasi, dan kristalisasi. Hasil penelitian menunjukkan bahwa proses kalsinasi terbaik adalah pada temperatur 700oC dan waktu proses 2 jam. Hasil terbaik diperoleh magnesium yang terekstraksi adalah 46%, dengan kadar kemurnian 72% dengan nilai persen ekstraksi 74,2%.

| Additional Information: | Magnesium carbonate is one of the magnesium-based carbonate minerals, known as hydromagnesite. The applications of magnesium carbonate materials include paper whitening, automotive industry, and cosmetics. As an archipelagic country, Indonesia has magnesium-based resources that can be used as raw materials for producing magnesium carbonate, such as dolomite, magnesite, bittern, and geothermal brine water processing waste. The brine water processing waste from Gunung Panjang Bogor contains various II-group carbonate compounds, such as magnesium carbonate, calcium carbonate, and strontium carbonate. This study aims to extract magnesium carbonate from lithium processing waste, which consists of solids containing magnesium carbonate, calcium carbonate, and strontium carbonate. The process used in this study is the partial calcination of magnesium carbonate at temperatures ranging from 600°C to 700°C. The research variables for partial calcination include calcination temperature variations (650°C, 675°C, 700°C, and 750°C) and calcination time (2, 4, and 6 hours). After calcination, further processes such as slaking, carbonation, and crystallization are conducted. The results indicate that the optimal calcination process occurs at a temperature of 700°C and a processing time of 2 hours. Under these conditions, the extracted magnesium was 46%, with a purity of 72% and an extraction percentage of 74.2%. | |||||||||
