Tourmaline, scheelite, and magnetite from orogenic gold deposits (n = 22) and glacial sediments (n = 5) of the Val-d'Or mining district (Québec, Canada) were investigated by Electron Probe Micro-Analyzer (EPMA) and Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) in order to determine their chemical signature and to assess their …
Gold-bearing ores contain gold hosted in various min-eralogical sites. Most common are free particles of gold and electrum, and inclusions of these phases in sulphide minerals.
Scheelite (CaWO 4) is a widespread accessory mineral associated with hydrothermal veins in the Archean gold deposits of the Kalgoorlie-Norseman region of Western Australia.Rare earth element (REE) and other trace element abundances in scheelite have been determined in situ by excimer laser ablation-inductively coupled plasma-mass spectrometry …

The crystal structure of scheelite belongs to the tetragonal system, with a space group of I4 1 /a and cell parameters of a = b = 0.5243 nm, c = 1.1376 nm, α = β = γ = 90°, and Z = 4 (Gao et al., 2016b).As shown in Fig. 1 (a), the complex anion in the crystal is a W–O 4 tetrahedron, formed by the combination of W 6+ and four O 2-and Ca 2+ ions, and the eight O …
Scheelite (CaWO 4) collected from 37 different ore-deposit settings (orogenic, sediment- and greenstone-hosted, skarn, porphyry, greisen, volcanogenic massive sulfide, breccia, and polymetallic deposits) globally was examined and evaluated using a combination of cathodoluminescence (CL), SEM-EDS, LA-ICP-MS, and δ 18 O analytical methods. These …
Hamid et al. [218] conducted a work index study on Mittersill scheelite ore, and it varied between 8.02 and 15.07 kWh/t according to the different feed particle sizes. Again, the study also revealed that most of the scheelite particles are liberated at a particle size ranging between 80 and 200 μm.

Tungsten ore is a rare metal that is widely distributed and exists in almost all kinds of rocks. Due to its low content, it can only be enriched through relevant geological processes before forming ore deposits for mining. At present, more than 20 types of tungsten ore have been found in nature, among which scheelite and wolframite are more valuable for mining and are also …

Ore shoots are typically sub-vertical with internal movement indicators suggesting a component of left lateral movement associated with the latest stibnite – quartz – gold vein breccia stage.
In this bulletin the subject of ore dressing is approached from the economic rather than from the technological standpoint, and the supporting data have been compiled with a view to their bearing upon the economic exploitation of ore deposits. Results obtained are stressed rather than the details of processes and the physics and chemistry involved. For discussions …
