A polymetallic replacement deposit is an orebody of metallic minerals formed by the replacement of sedimentary, usually carbonate rock, by metalbearing solutions in the vicinity of igneous intrusions. When the ore forms a blanketlike body along the bedding plane of the rock, it is commonly called a manto ore ore geometries are chimneys and veins.
You do not know what Disseminated Polymetallic Ore Deposits or Complex Mineralogy until you have seen a QEMSCAN like this: With simple main observations as crazy as these below. ***The proportion of each mineral liberated at a 56µm grind P80 was: Chalcopyrite — 36% liberated Galena — 12% liberated Sphalerite — 45% liberated Pyrite — 85% liberated ***The most abundant binary composites ...
Basemetalpoor, highgrade gold deposits of low sulphidation character occurring in continental sedimentary rocks of synextensional basins (, Ada Tepe) show a close spatial and temporal relation to detachment faulting prior and during metamorphic core complex formation. Their
Roughly 80 tons of gold, 4 000 tons of silver, 70,000 t of Zn, 55,000 t of Pb and 8,000 t of Cu have been produced during one thousand years of mining. The Kremnica epithermal gold deposit has produced around 20 t gold since the 12 th century and the same amount of gold is available in reserves of the planned open pit operation.

Hydrothermal monazite coprecipitated with goldhosting ore minerals (, magnetite, pyrite and chalcopyrite) was identified in the highgrade skarn gold ores from the worldclass Beiya polymetallic gold deposit. In situ SIMS UThPb dating of monazite reveals variable fractions of common Pb and the influence of excess 206 Pb.
In the case of small or complex polymetallic deposits, it may be considered to ship a bulk concentrate resulting in a lower net smelter return, as opposed to operating the equipment required to separate the minerals .Polymetallic projects such as McArthur River, Australia and Red Dog, Alaska have benefited from bulk leadzinc concentrates.
A technical design team with experience in all the comminution technologies used in crushing, conveying, grinding, gravitygold separation, and classifying is extremely valuable. With an increase in complex polymetallic deposits, a team experienced in flotation across a wide range of minerals can drive the success of a project.

polymetallic replacement deposits are associated with skarn deposits in which host carbonate rocks are replaced by calcsilicate±iron oxide mineral assemblages. Most polymetallic vein and replacement deposits are zoned such that coppergold ore is proximal to intrusions, whereas leadzincsilver ore is laterally and vertically distal to ...
polymetallic base metal ores, and refractory gold or es [12]. For the biomining of gold and some other precious metals, microorganisms are used to remove minerals that occlude target metals which are solubilized in a second process (, by extracting with cyanide or thiosulfate in the case of gold) [13].
quartzgoldsilver deposits; (4) skarn gold deposits; (5) postmagmatichydrothermal goldpolymetallic deposits; (6) gold placers. In some areas the superposition of different mobilization, generation and regeneration processes in time and space lead to the foonation of more complex polygenic and polychronous goldbearing deposits. The proposed ...
