2016-10-22 · According to the ore composition and structural features of black-shale blocks, the studied subjects are associated with big large-volume gold deposits belonging to black-shale formation: 1) dispersed, finely disseminated condition of noble metal mineralization; 2) presence of carbonaceous matter in ore-bearing rocks; 3) presence of nativeBanded iron formations, pyritic black shale, and gold,Banded iron formations (BIF) are predominantly Precambrian sedimentary rocks composed of alternating layers of iron-rich minerals (commonly hematite and magnetite, but also siderite, chlorite, and grunerite) and silica-rich minerals (e.g., quartz or chert) in which the Fe content of the entire rock is at least 15 wt. %. Although typically thought of as strictly Fe resources, such as
2014-12-1 · The origin of fluid involved in black shale gold deposits is an ongoing controversy. Many researchers insisted that ore fluids of orogenic gold deposits are of metamorphic origin (Groves et al., 1998, Kerrich and Cassidy, 1994, McCuaig Synsedimentary to Early Diagenetic Gold in Black Shale,Gold content is particularly high in the Paringa Basalt interflow shale nodules, which average 3 to 4 ppm Au as well as 30 to 40 ppm Ag, 30 to 40 ppm Te, and 1,000 ppm As. Samples taken several kilometers to the south (along strike) and west of the Golden Mile of the Kapai Slate and Black Flag Group shale also contain disseminated and nodular
These processes release gold, arsenic, sulfur and other elements (Sb, Te, Cu, Zn, Mo, Bi, Tl, and Pb) from the source rocks to become concentrated by hydrothermal processes, locally to produce gold ores, in structural sites such as fold hinge zones, shear or breccia zones within or above the black shale sequence.Synsedimentary to early diagenetic gold in black shale,The Kalgoorlie goldfield (~50 Moz Au produced), famous for its long mining history and diversity of precious metal telluride minerals, is a world-class Neoarchean Au-Ag-Te district, which includes the Golden Mile Super Pit, the largest single gold deposit in the Eastern Goldfields of Western Australia, and the smaller but nonetheless significant Mount Charlotte deposit, 3 km to the north.

2021-11-23 · The refractoriness of gold ores occurs by occlusion or entrapment of subatomic gold particles in matrices of sulfide minerals (pyrite, arsenopyrite, stibnite, etc.) and insoluble siliceous gangue, by association with tellurides, clays and carbonaceous matter .The carbonaceous material can adsorb gold, an effect known as preg-robbing, from the solution similar to Gold losses from cyanide solutions Part I: The influence,2000-8-1 · Shale material from Beatrix Gold Mine in South Africa has been found to be capable of adsorbing gold from cyanide solutions. Black shale bands occur in the reef zone at Beatrix Mine, but because of the mode of occurrence of the shale bands selective mining cannot be practised and ore delivered to the plant is contaminated by shale.
A shale with at least 1% carbonaceous material indicating a reducing environment. A dark, thinly laminated carbonaceous shale, exceptionally rich in organic matter (5% or more carbon content) and sulfide (esp. iron sulfide, usually pyrite), and often containing unusual concentrations of certain trace elements (U, V, Cu, Ni).It is formed by partial anaerobic decay of buried organic GEOLOGY OF SEDIMENTARY ROCK-HOSTED GOLD ,2001-3-16 · sedimentary rock-hosted gold deposits in P.R. China. These breccia bodies are conformable with stratigraphic units in the host rock. An example of this is the Shuangwang gold deposit (Fan, S.C. and Jin, Q.H., 1994), which is a large Carlin-type gold deposit in the Qinling area, hosted by stratabound breccia bodies (fig. 29),
The majority of the gold recovered from mining the Forgotten Four mine was from shear bound quartz vein stockworks or sheeted veins and quartz carbonate veins within a narrow carbonaceous shale (dipping 40⁰-60⁰ east), positioned within a granophyric quartz dolerite with carbonate-sericite-sulphide altered wall rocks.': It' USGS,2010-10-31 · Of the 66 named mining districts in Elko County, 56 have been pro ductive of one or more of 19 different commodities: 11 metals copper, gold, silver, lead, zinc, mercury, tungsten, manganese, iron, uranium, and antimony; 8 nonmetals sand and gravel, stone, barite, diatomite, gems, oil shale, volcanic ash, and clay.
