Metallogeny of the syenite-related Dongping gold

2016-3-1  The genetic link between the Shuiquangou syenite intrusion and the gold mineralization is consistent with the observation that 13 gold deposits occur within or adjacent to the Shuiquangou syenite intrusion (Li et al., 2000b, Song and Zhao, 1996, Wang et al., 1990, Yin, 1994), whereas there is no gold mineralization related to the abundant Triassic and Jurassic to Cretaceous granite intrusions in the

Cyanide Use in Gold Mining - Earthworks

How is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold

Structural setting of the Young-Davidson syenite

2014-7-1  Syenite-hosted veins and associated gold mineralization. Gold was first reported in the Matachewan area in 1901, and the Young-Davidson and Matachewan Consolidated mines were discovered in 1916 and 1917, respectively (Lovell, 1967, Sinclair, 1982). Mineralization in the two mines is spatially continuous, and is considered to be one deposit, the Young-Davidson deposit.

Cyanide hazards to plants and animals from gold

Cyanide extraction of gold through milling of high-grade ores and heap leaching of low-grade ores requires cycling of millions of liters of alkaline water containing high concentrations of potentially toxic sodium cyanide (NaCN), free cyanide, and metal-cyanide complexes. Some milling operations result in tailings ponds of 150 ha and larger.

Archean high-Mg monzodiorite–syenite, epidote

2007-12-19  Gold-bearing reverse faults displace the syenite porphyry (Fig. 8a) and the biotite–calcite veins (Fig. 8c) and are marked by fractures and quartz–dolomite veins (0.1–2 cm) containing minor albite, microcline, pyrite, and accessory sericite and biotite. Thicker quartz breccia veins (5–20 cm), mostly located at the boundaries of major faults, enclose fragments of altered wall rock and aggregates of

Galloway Project Gold deposits Fokus Mining

The gold mineralization is associated with a decametric syenite dike in mafic lapilli tuffs mineralized with pyrite and chalcopyrite. Hole VHD-12-57 intersected 2.68 g/t Au over 9.0 m (210-222 m) in what appears to be an ultrabasic dike or sill in mafic tuffs. It is mineralized with pyrite and traces of malachite.
