Abstract

Penelitian ini bertujuan untuk mensintesis prinsip-prinsip ekstraksi selektif dari literatur terkini guna mengembangkan kerangka kerja terpadu untuk sistem ekstraksi dan pemurnian emas nonmerkuri yang berkelanjutan. Melalui tinjauan sistematis terhadap 18 artikel kunci, dianalisis tiga aspek utama : (1) adaptasi metodologi ekstraksi selektif, (2) integrasi teknologi pemurnian bertingkat, dan (3) integrasi kerangka keberlanjutan dan tata kelola. Hasil sintesis mengungkapkan bahwa selektivitas tinggi dapat dicapai melalui kombinasi pretreatment bijih, kontrol ketat parameter proses (terutama pH), dan optimasi multivariat dengan desain Taguchi dan Central Composite Design (CCD). Lebih lanjut, integrasi Magnetic Solid-Phase Extraction (MSPE) menggunakan nanopartikel terfungsionalisasi dan elektroflotasi menciptakan sistem "penyaringan ganda" yang efektif untuk menghasilkan umpan elektrowinning berkemurnian tinggi. Kesimpulan penelitian menegaskan bahwa solusi teknis yang viable harus diintegrasikan dengan prinsip ekonomi sirkular (Lèbre et al., 2017) dan kerangka tata kelola inklusif (OPIDD) sejak fase desain. Dengan demikian, penelitian ini berkontribusi pada bidang ilmu metalurgi ekstraktif dan pengelolaan sumber daya berkelanjutan dengan menyajikan sebuah pendekatan holistik yang memadukan kemajuan teknis, pertimbangan lingkungan, dan keadilan sosial.
