La production chinoise d'enrichissement du minerai de wolframite a plus de 70 ans d'histoire et a accumul\u00e9 une riche exp\u00e9rience, qui peut \u00eatre r\u00e9sum\u00e9e comme suit.<br \/>\n1. Pr\u00e9-enrichissement : les st\u00e9riles sont d'abord jet\u00e9s, puis lav\u00e9s, d\u00e9simpr\u00e9gn\u00e9s, calibr\u00e9s et concass\u00e9s.<br \/>\nLe taux de dilution de l'extraction de wolframite est g\u00e9n\u00e9ralement de l'ordre de 80%. La quantit\u00e9 de roches environnantes dans le minerai est importante et il est facile de les distinguer des roches contenant de la wolframite. La pr\u00e9s\u00e9lection des st\u00e9riles augmente la capacit\u00e9 et l'efficacit\u00e9 du traitement d'enrichissement et r\u00e9duit l'usure du concasseur.<\/p>\n<p>2.

Concentration fine des boues de wolframite<br \/>\nLes boues fines de wolframite comprennent les boues primaires et secondaires, qui repr\u00e9sentent environ 10% du minerai d'origine. La teneur en tungst\u00e8ne est sup\u00e9rieure \u00e0 celle du minerai d'origine, de 141 \u00e0 151 TTP3. L'extraction du tungst\u00e8ne de la boue est une m\u00e9thode importante pour am\u00e9liorer le taux de r\u00e9cup\u00e9ration du tungst\u00e8ne.<br \/>\nLes machines de concentration des boues de wolframite comprennent des tables \u00e0 secousses, des concentrateurs centrifuges, des goulottes \u00e0 courroie, la flottation, la s\u00e9paration magn\u00e9tique. Le taux de r\u00e9cup\u00e9ration des boues fines est pass\u00e9 de 10% ~ 50% \u00e0 60%~70%.<\/p>\n<h3>\u00c9tude de cas : usine de wolframite<\/h3>\n<p>Prenons l'exemple de l'usine de tungst\u00e8ne et de wolframite de Pangushan et \u00e9tudions plus en d\u00e9tail le flux et la technique de traitement du minerai de tungst\u00e8ne.<\/p>\n<p>\u3010Ore caract\u00e9ristiques\u3011<br \/>\nComposition min\u00e9rale : Gisement composite de type quartz-wolframine-sulfure, contenant principalement de la wolframite, de la bismuthinite, des min\u00e9raux auxiliaires tels que la scheelite, la pyrite, la pyrrhotite, la molybd\u00e9nite et la chalcopyrite.<br \/>\nLes roches environnantes sont principalement constitu\u00e9es de quartz, d'ardoise et de phyllite.<br \/>\n\u3010Capacit\u00e9\u3011800t\/d<br \/>\n\u3010Target minerals\u3011<br \/>\nwolframite, scheelite, bismuth et argent.<br \/>\n\u3010Extraction et valorisation\u3011<br \/>\nConcassage - lavage - cueillette manuelle - broyage - concentrateur \u00e0 jigs - table \u00e0 secousses - flottation - s\u00e9paration magn\u00e9tique.<br \/>\nLe processus de traitement complet est divis\u00e9 en quatre parties : s\u00e9paration primaire, s\u00e9paration par gravit\u00e9, r\u00e9cup\u00e9ration des boues et concentration.<br \/>\n\u3010Equipment\u3011<\/p>\n<table style=\"border-style: solid;
