Penelitian ini bertujuan untuk mengetahui kandungan magnesium dan mangan, serta mengetahui jenis pelarut dan pengaruh waktu destruksi pada penentuan kandungan magnesium dan mangan dalam bijih besi. Penelitian ini menggunakan metode destruksi basah, dimana proses pendestruksian dilakukan dengan beberapa variasi yaitu variasi pelarut (HCl pekat, HNO pekat dan campuran HCl pekat dan HNO 3 3 pekat dengan perbandingan 3:1), dan variasi waktu destruksi 1,5 jam; 2,0 jam; 2,5 jam; 3,0 jam; dan 3,5 jam. Dari penelitian ini diperoleh kandungan logam magnesium tertinggi adalah 1,020 % dan kandungan logam mangan sebesar 1,504 % dengan pelarut yang sama, yaitu aquaregia, pada ukuran partikel sampel ≤63µm dan waktu destruksi 3,5 jam.</mods:abstract><mods:classification authority="lcc">LC Special aspects of education</mods:classification><mods:classification authority="lcc">QD Chemistry</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8601">2011</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Universitas Negeri Padang;Kimia FMIPA UNP</mods:publisher></mods:originInfo><mods:genre>Thesis</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_46698"><mets:rightsMD ID="rights_eprint_46698_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
