lengkap<\/b><\/strong><\/p>\n<p>Karena mineral tungsten rapuh dan mudah berlumpur selama proses penghancuran dan penggilingan, metode seperti penggilingan tahap, pemisahan tahap, penggilingan kasar dan panen awal, proses gabungan pemisahan gravitasi-flotasi, dll., Sering digunakan untuk memulihkan mineral tungsten berbutir kasar. Untuk memulihkan molibdenum, bismut, tungsten, dan fluorspar dalam bijih secara wajar, aliran proses utama flotasi total, pemisahan gravitasi-flotasi, dan flotasi-pemisahan gravitasi-flotasi diusulkan.<\/p>\n<p>&nbsp;<\/p>\n<h3>Proses flotasi penuh<\/h3>\n<p>Bijih mentah digiling sekali hingga mencapai ukuran partikel (90%-74\u03bcm), di mana semua mineral berharga dipisahkan menjadi monomer. Bijih sulfida diapungkan terlebih dahulu, kemudian mineral tungsten diapungkan, dan terakhir, fluorspar diapungkan. Keuntungan dari proses ini adalah bahwa bijih sulfida dipulihkan pada satu waktu, hanya dengan operasi flotasi, bubur diangkut dengan lancar, dan aliran proses relatif sederhana. Kerugiannya adalah bahwa bijih mentah digiling halus pada satu waktu ke ukuran partikel di mana monomer mineral yang berharga dipisahkan, dan mineral tungsten mudah berlumpur, yang mempengaruhi peningkatan tingkat pemulihan tungsten.<\/p>\n<p>&nbsp;<\/p>\n<h3>Proses pengapungan gravitasi<\/h3>\n<p>Bijih mentah digiling hingga berukuran -0,5 mm dan pertama-tama dilakukan pemisahan gravitasi untuk mendapatkan pasir kasar hasil pemisahan gravitasi. Tailing kemudian digiling menjadi ukuran partikel di mana semua mineral yang berguna dipisahkan monomernya (90%-74\u03bcm), dan kemudian bijih sulfida, mineral Tungsten, dan fluorit. Setelah pemisahan gravitasi dan penyesalan, bijih sulfida dan scheelite dipulihkan dengan urutan flotasi, dan tailing dipulihkan dengan <a href=\"https:\/\/www.jxscmachine.com\/id\/pemisah-gravitasi\/meja-goyang-emas\/\">meja goyang<\/a> untuk memulihkan wolframite. Proses tulang punggung flotasi-pemisahan gravitasi lainnya menggunakan pemisahan gravitasi (<a href=\"https:\/\/www.jxscmachine.com\/id\/pemisah-gravitasi\/parasut-spiral\/\">parasut spiral<\/a>) untuk memproses pasir yang mengendap di sirkuit penggilingan untuk mendapatkan pasir kasar hasil pemisahan gravitasi. Proses tulang punggung pemisahan gravitasi-flotasi lainnya sama dengan proses tulang punggung pemisahan gravitasi-flotasi di atas. Keuntungan dari proses ini adalah bahwa penggilingan kasar dan pemisahan gravitasi dapat memulihkan tungsten dan mencegah penggilingan berlebih pada mineral tungsten, yang bermanfaat bagi pemulihan tungsten. Kerugiannya adalah beberapa mineral molibdenum sulfida dan bismut sulfida juga masuk ke dalam pasir kasar yang dipilih secara gravitasi dengan mineral tungsten berbutir kasar. Oleh karena itu, ada dua sistem untuk pemulihan molibdenum, bismut, dan tungsten. Alur prosesnya relatif rumit, sehingga menimbulkan ketidaknyamanan dalam manajemen produksi.<\/p>\n<p>&nbsp;<\/p>\n<h3>Aliran proses flotasi-gravitasi-flotasi<\/h3>\n<p>Giling bijih hingga 60%-65%-74\u03bcm, pertama-tama mengapungkan mineral sulfida molibdenum dan bismut, dan melakukan pemisahan gravitasi <a href=\"https:\/\/www.jxscmachine.com\/id\/proses-flotasi-mineral-sulfida\/\">tailing flotasi bijih sulfida<\/a> untuk mendapatkan konsentrat campuran tungsten hitam dan putih, dan kemudian menggiling tailing menjadi 90%-74\u03bcm. Flotasi berurutan memulihkan bijih sulfida, mineral tungsten, dan fluorspar. Mirip dengan proses tulang punggung pemisahan gravitasi-flotasi, keuntungan dari proses ini adalah tungsten dipulihkan dengan penggilingan kasar dan pemisahan gravitasi, tingkat lumpur mineral tungsten rendah, dan tingkat pemulihan tungsten tinggi. Kerugiannya adalah pemisahan gravitasi pasir kasar dan tailing flotasi bijih sulfida memerlukan pemulihan molibdenum, bismut, dan tungsten, dan aliran prosesnya rumit.<\/p>\n<p>&nbsp;<\/p>\n<table border=\"1\" width=\"100%\">\n<tbody>\n<tr>\n<td style=\"text-align: center;\" colspan=\"6\"><strong><b>Tabel 7: Keuntungan dan Kerugian dari 3 Proses<\/b><\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Alur Proses<\/td>\n<td style=\"text-align: center;\">Tingkat Mudifikasi Mineral Tungsten<\/td>\n<td style=\"text-align: center;\">Sistem Pemulihan Mineral Molibdenum, Bismut &amp; Belerang<\/td>\n<td style=\"text-align: center;\">Sistem Pemulihan Mineral Tungsten<\/td>\n<td style=\"text-align: center;\">Kompleksitas Proses<\/td>\n<td style=\"text-align: center;\">Manajemen Produksi<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Flotasi Penuh<\/td>\n<td style=\"text-align: center;\">Lebih besar<\/td>\n<td style=\"text-align: center;\">1 pcs<\/td>\n<td style=\"text-align: center;\">1 pcs<\/td>\n<td style=\"text-align: center;\">Lebih sederhana<\/td>\n<td style=\"text-align: center;\">Lebih nyaman<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Pemisahan Gravitasi - Flotasi<\/td>\n<td style=\"text-align: center;\">Kecil<\/td>\n<td style=\"text-align: center;\">2 pcs<\/td>\n<td style=\"text-align: center;\">2 pcs<\/td>\n<td style=\"text-align: center;\">Lebih kompleks<\/td>\n<td style=\"text-align: center;\">Tidak nyaman<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Flotasi - Pemisahan Gravitasi - Flotasi<\/td>\n<td style=\"text-align: center;\">Kecil<\/td>\n<td style=\"text-align: center;\">2 pcs<\/td>\n<td style=\"text-align: center;\">2 pcs<\/td>\n<td style=\"text-align: center;\">Lebih kompleks<\/td>\n<td style=\"text-align: center;\">Tidak nyaman<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p><strong><b>Larutan flotasi campuran bijih sulfida sepenuhnya<\/b><\/strong><\/p>\n<p>Senyawa minyak non-polar dan sulfhidril digunakan sebagai pengumpul untuk mengapungkan semua mineral sulfida dari bijih mentah. Tailing masuk ke dalam sirkuit flotasi tungsten, dan kapur ditambahkan ke dalam konsentrat campuran bijih sulfida untuk menekan pirit. Tailing adalah konsentrat pirit, produk busa adalah konsentrat campuran molibdenum-bismut, produk busa adalah konsentrat molibdenum, mineral molibdenum pengapungan, produk busa adalah konsentrat molibdenum, dan tailing adalah konsentrat bismut. Aliran proses yang sederhana mencirikan proses tersebut. Kerugiannya adalah bahwa daya apung alami mineral tidak dimanfaatkan, pemisahan molibdenum dan bismut serta pemisahan bismut dan belerang sulit dilakukan, dan kualitas konsentrat molibdenum dan konsentrat bismut bisa lebih baik.<\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>Larutan yang dapat mengambang seperti molibdenum dan bismut<\/b><\/strong><\/p>\n<p>Gunakan minyak non-polar sebagai pengumpul untuk mengapungkan semua mineral molibdenum dan mineral bismut yang paling mudah terapung dari bijih mentah.
