TL;DR: In this article, the effects of processing parameters, such as calcination temperature, holding time and calcium carbonate dosage on conversion ratio of wolframite were investigated, and the results demonstrated that 97.58% of the Wolframite was converted to scheelite in 2h at temperature of 800°C under the condition of calcium carbonates stoichiometric ratio of 1.3.
Abstract: Scheelite was successfully prepared by solid-state calcination synthesis using wolframite [(Fe,Mn)WO 4 ] and calcium carbonate as materials in air atmosphere. The effects of processing parameters, such as calcination temperature, holding time and calcium carbonate dosage on conversion ratio of wolframite were investigated. The conversion of wolframite increased with increasing of temperature, holding time and calcium carbonate dosage. The results demonstrated that 97.58% of wolframite was converted to scheelite in 2 h at temperature of 800 °C under the condition of calcium carbonate stoichiometric ratio of 1.3, and the corresponding reaction products are scheelite, iron oxide and manganese dioxide.

TL;DR: The flotation results show that Ca2+ significantly reduces the flotation recovery of scheelite using single dodecylamine (DDA) or single sodium oleate (NaOL) as mentioned in this paper.
Abstract: The flotation results show that Ca2+ significantly reduces the flotation recovery of scheelite using single dodecylamine (DDA) or single sodium oleate (NaOL), whereas Ca2+ hardly affects scheelite ...

TL;DR: The mineral chemistry of the scheelite samples indicate that the ore-forming fluids of the Dahutang deposit were dominated by magmatic hydrothermal fluids during the early stage, and that meteoric water was added during fluid evolution as mentioned in this paper.

TL;DR: In this paper, the authors analyzed the Sm-Nd isotopic compostions in scheelite concentrates and obtained a SmNd isochron age of 212 ± 20 Ma (MSWD = 0. 52).
Abstract: Gaoling quartz-vein type tungsten deposit is located in southern margin of the Miao 'ershan—Yuechengling batholith. The granitic rocks closely associated with tungsten mineralization can be divided into two facies according to the contents of phenocrysts: medium- to fine-grained porphyritic two-mica granite,and mediumto fine-grained two-mica granite. Whole rock chemical analyses indicate that the granitic rocks have high Si O2 and are metaluminous to slightly peraluminous,which belong to typical highly fractionated S-type granites. They have relatively low total REE contents and are enriched in LREE,Cs,Rb,Th,U,Pb,depleted in HREE,Ba,Sr,Ti.In-situ LA-ICP-MS zircon U-Pb chronology indicates that the granitic pluton was emplaced at 224. 9 ± 1. 4 to 220. 2± 1. 6 Ma. Furthermore,we analyzed the Sm-Nd isotopic compostions in scheelite concentrates and obtained a SmNd isochron age of 212 ± 20 Ma( MSWD = 0. 52). The result suggests that the tungsten mineralization in Gaoling depositis the response of the Triassic tungsten mineralization event in the western Nanling Range. The detailed observations of ore minerals under optical microscope and EPMA show the Gaoling tungsten deposit was formed in two mineralization stages:( 1) wolframite—scheelite—quartz vein stage;( 2) scheelite( wolframite) —sulfide—quartz vein stage. eNdvalues of the scheelite concentrates range from- 8. 9 to- 9. 4,which is correspond with the crustal origin of typical highly fractionated S-type granite and indicates that the parental granite was formed by the partial melting of the crustal basements.
