The lack of information on the metallurgical performance of the mineralization. Whereas polymetallic deposit can be of very high grade such as indicated at Rupice, they are usually also metallurgically complex with relatively low recoveries and deleterious elements that find their way in concentrates resulting in penalties.
The Qibaoshan area, located to the northwest of Wulian town in Shandong Province, is an important polymetallic ore field. Four mediumsized ore deposits have been discovered so far: the Jinxiantou Au–Cu deposit, the Changgou Cu–Pb–Zn deposit, the Hongshigang Pb–Zn deposit, and the Xingshanyu Pb–Zn deposit.
The widespread mineralization is predominantly in the form of quartz +/ carbonate highgrade polymetallic veins rich in silver, lead, zinc, copper and gold. Mineralization is primarily hosted in the middle Jurassic Hazelton Group volcanics and sediments, and is intruded by Eocene phases of the Coast Plutonic Complex.

iron and silver, (Fe,Ag),S, and an unusual (antimonian) variety of free gold, Auo,uSbo ou, are also found in the ores. The presence of this complex of rare and new minerals of manganous metasomatite and ore indicates the specific conditions of formation of the deposit. Introduction This deposit of South Primorye is in the zone of the

Introduction In addition to tin and fluorite mineralization the granites The Bushveld Complex is the world's largest known are host to a range of polymetallic mineralization that igneous complex and is host to the world's largest includes base and precious metals, as described by platinum, vanadium and chromium deposits.

The mineralization potential is consisted of magmatic porphyry copper type deposits, hypothermal/ mesothermal mantotype polymetallic sulphides and epithermal gold systems (Arvanitidis 2010).

The mathematical description of the electron mechanism of reduction of metals from complex polymetallic types of ore has been suggested. The description of the mechanism was based on diffusion and thermal processes occurring in the phases of a reducing agent and an oxide, and chemical reactions on the surface of a phase boundary. The effect of the major physicschemical parameters on the rate ...
Oct 26, 2018· Drilling at RupiceIntroductionThis time Kees Dekker analyzes Adriatic Metals, an Australian junior exploring a very high grade polymetallic project called Rupice in Bosnia Herzegovina. Kees and I had our doubts as the last drill results at the border of the drill permitted area took a very long time until release, but when they did came in, the results appeared to be pretty good again.

Aftabrou polymetallic prospect is located at the contact of OligoMiocene calcalkaline granodioritic to dioritic and Eocene andesitic to basaltic volcanic complex in middle section of UrumiyehDokhtar volcanic arc in NW of Saveh city. Petrographic study indicated that the volcanic rocks are mostly: lava and tuff. Composition of lavas is mainly andesite and tuffs are mainly composed of dacite ...
