Commonly used collectors for scheelite are oleic acid, oleic acid soap and 731 oxide paraffin soap. There was once a beneficiation plant that used high-temperature beneficiation to select scheelite. The production technical indicators: the grade of scheelite concentrate was 67.03%, the tailings was 0.095%, and the recovery rate was 80.17%.
The aim of this study was to develop a comprehensive technology for the utilization of tailings from quartz vein-hosted gold deposits. We investigated the recovery potential and separation process for gold, feldspar, and quartz from tailings samples collected from the Jinqu gold mine in Henan province, China. The sequence of the …

Scheelite is a common accessory mineral in hydrothermal gold deposits and is paragenetically related to the deposition of gold (Uspensky et al., 1998). Scheelite (CaWO 4) crystallizes in the tetragonal system and elements such as Na, Sr, Y Pb and REE can substitute for Ca 2+ in the scheelite structure (Cottrant, 1981, Raimbault et al., 1993).

The association between gold and scheelite in orogenic gold deposits has long been recognized. Goldfarb et al. (2005)re-view the characteristics of orogenic gold deposits. In many deposits, scheelite predates and/or is contemporaneous with gold deposition, such as in the Val-d'Or district, Canada (Beaudoin and Pitre 2005), at Mt. Charlotte ...
Gold and silver recovery from gold tailings by CIP. All-slime cyanidation carbon pulp gold extraction technology can recover the gold and silver from the old gold tailings. Xinhai …
1. Introduction. Scheelite (CaWO 4) is one of the main sources of tungsten, alongside with the other monotungstates stolzite (PbWO 4) and wolframite (a solid solution of ferberite (FeWO 4) and hübnerite (MnWO 4)).Scheelite is however more common and is found in approximately 65% of known tungsten deposits [1].Pale white to brown-orange, …
The manuscript divulged the potential use of Falcon concentrator in recovering fine and ultrafine scheelite values present in the Hutti gold mine tailings.
The Zhaishang Carlin-like gold deposit in the Qinling Orogen is a giant Au deposit, hosting 127t of Au @ 2.67 g/t with economic concentrations of tungsten and …

In this work, the development of low-grade scheelite recovery from molybdenum tailings in Luanchuan area is reviewed, including ore properties, …
The separation of scheelite and barite. It is difficult to separate scheelite and barite by sodium silicate because of the closed inhibitory action for scheelite and barite. We choose alkyl sulfate as collector to repeatly select barite under the 1.5-3PH, and the product in tank is scheelite. The separation of scheelite and sulfide
New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources.
Investigations were conducted by the U.S. Bureau of Mines to develop flowsheets for the recovery of tungsten and gold from four Alaskan scheelite-bearing
Recently special gravity concentration equi-pment such as Bartles Mozley Separator (MIS)and Cross Belt Concentrator (CBC) have been used in separation of a wide variety …

A thin film (~50 nm) of gold was deposited on the cross-section of the mortar bars for 4 min at a current of 10 mA using a U SC–701 device. Figure 4 presents a flowchart summarizing the steps of the methodology used in this study. 3. …
New ceramic formulations based on scheelite tailing were developed, and their potential in the ceramic industry was evaluated. Green bodies with different contents of scheelite tailing (0–8 wt%) were sintered (1150 °C, 1200 °C, and 1250 °C) and characterized in terms of the main mineralogical phases, microstructure, and physico …
The separated gold tailings slurry is dewatered by the tailings dewatering equipment and then sent to the mine for dry stacking. This is an effective way to increase the storage capacity pressure of the tailings pond, reduce the potential safety hazards of the tailings pond and reduce the environmental pollution of the tailings.
