Gold/Auriferous Deposits can be classified into types for which here is a List of 10 Types of Gold Deposits: ... lodes, stockworks and silicified zones in a complex geological environment with sedimentary, volcanic and various igneous intrusive + granitic rocks.
The Berezitovoe gold-polymetallic deposit is located within the Urusha-Oldoi ore-placer district of the Sergachi metallogenic belt in the Amur River head (Amurskaya Oblast' of the Russian Federation).
A northerly trending zone of porphyry Cu-Au, porphyry Au, polymetallic replacement Pb-Zn-Au-Ag, and sedimentary rock-hosted Au deposits along the northwest margin of the Late Cretaceous Timok Magmatic Complex forms a part of the Bor metallogenic zone in eastern Serbia.
Key words: polymetallic copper–gold deposits, genetic types, metallogenic model, magmatic–hydrothermal system, Tongling ore district, Anhui Province Citation: Fu et al., 2019. Genetic Types and Metallogenic Model for the Polymetallic Copper–Gold Deposits in the Tongling Ore District, Anhui Province, Eastern China.
Underground bulk samples have been taken from the Main Zone to conduct metallurgical test work. The Main Zone is a complex polymetallic deposit high in arsenic concentrations which create a challenge in the production of saleable zinc and lead concentrates and the economic recovery of gold.
This paper presents mineral prospectivity mapping to identify potential new exploration ground for polymetallic Sn–F–REE mineralization associated with the Bushveld granites of the Bushveld Igneous Complex, South Africa. The Lebowa Granite Suite, commonly known as the Bushveld granites, is host to a continuum of polymetallic mineralization with a wide range of metal assemblages (Sn–Mo ...
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 ...
Abstract. This paper presents mineral prospectivity mapping to identify potential new exploration ground for polymetallic Sn–F–REE mineralization associated with the Bushveld granites of the Bushveld Igneous Complex, South Africa.
Polymetallic Flotation Equipment - Complete Ore Process Plant. This ore processing plant is for the flotation of 2 base metals (Cu/Pb/Zn/Co/Ni/etc) which may or may not contain precious metals These ore deposits are called polymetallic by geologists and metallurgists This system allows you to recovery by way of differential or sequential flotatio, the sulphide metals in 2 separate concentrates ...

A polymetallic replacement deposit is an orebody of metallic minerals formed by the replacement of sedimentary, usually carbonate rock, by metal-bearing 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 deposit.Other ore geometries are chimneys and veins.
Hydrothermal monazite co-precipitated with gold-hosting ore minerals (e.g., magnetite, pyrite and chalcopyrite) was identified in the high-grade skarn gold ores from the world-class Beiya polymetallic gold deposit. In situ SIMS U-Th-Pb dating of monazite reveals variable fractions of common Pb and the influence of excess 206 Pb.

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.

polymetallic replacement deposits are associated with skarn deposits in which host carbonate rocks are replaced by calc-silicate±iron oxide mineral assemblages. Most polymetallic vein and replacement deposits are zoned such that copper-gold ore is proximal to intrusions, whereas lead-zinc-silver ore is laterally and vertically distal to ...
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 lead-zinc concentrates.

Gold-bearing Polymetallic Veins and Replacement Deposits Part II Gold in the Tintic Mining District, Utah By Hal T. Morris Abstract Gold is the fourth most important mineral commodity produced from the Tintic mining district after silver, lead, and zinc. Some of this gold is produced as a byproduct or
All the same types of mineral deposits occur under the ocean such as epithermal gold, porphyry, and placer. There are also diamond pipes, massive sulphides and everything else that we mine at the surface. Deposits. The ocean also has types of deposits that we can't find on land. One special mineral deposit is called Polymetallic Nodules.
Furong Sn-polymetallic ore field, Qitianling complex, Beihu District, Chenzhou, Hunan, China : Tin ore field with estimated reserves of 600,000 tons of ore grading at 0.8% Sn, located in the southern part of the Qitianling granite complex and its contact zone. The deposit consists of three ore ...
A technical design team with experience in all the comminution technologies used in crushing, conveying, grinding, gravity-gold 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.
