Abstract (EN): The production of high-grade scheelite concentrates from low-grade ores involves a set of operations to eliminate the undesirable minerals. The present work includes as main goals the study of the effect of (i) meteorization of the ore, (ii) pH during the grinding, (iii) the amount of soda ash in grinding process, (iv) the depression or previous flotation of sulphides, (v) and the acidification of the silicate solution on the scheelite grade and tungsten recovery from flotation of Tarouca tailings. The studies which led to the conditions to produce a 72% WO3 concentrate at a 71% recovery from fresh tailings assaying 0.52% WO3, using Pamak-4 as collector are presented.
