Упрощенное унифицированное определение меди (цинка, кадмия) в медных и свинцово-цинковых рудах

Porphyry Cu deposits in the Chilean and Argentinian central Andes occur in a series of orogen-parallel magmatic arcs, which migrated episodically eastward since the Early Cretaceous. The three Cenozoic belts, corresponding to Paleocene-early Eocene, middle Eocene-early Oligocene, and Miocene-early Pliocene epochs, cut obliquely across a composite belt of subeconomic porphyry Cu mineralization formed at several times during the Late Carboniferous to Triassic interval.

Copper belongs to those metals whose concentrations in nature arise from a broad diversity of endogeneous and exogeneous processes, which applies to essentially all genetic classes of ore deposits.

This is the first proceedings volume on copper metallogeny to cover the worldwide distribution of the four main groups of copper deposits, including in Part I: copper-nickel deposits with cobalt and platinum group elements; Part II: copper-molybdenum-gold deposits with silver, zinc, and lead; Part III/IV: copperzinc-lead deposits (with silver etc.).

In August 1882, the Morgan brothers recognised a mineral deposit, now known as the Mount Morgan Gold-Copper Deposit. The final production figures for the mine were 250 tonnes of gold and 360,000 tonnes of copper from 50 million tonnes of ore, making the average grades 4.99g/t gold and 0.72% copper.

Among the strata-bound ore deposits, the group of sandstone-type, sometimes called red-bed type, forms a complex case of genetic problems related to the detrital1 nature of the ore-bearing facies. The group of the so-called red-bed deposits appears to be homogeneous, even if some transitions are frequent, both towards volcano—sedimentary deposits and towards Kupferschiefer2.

Тектонический контроль, реконструкция и консервация тигелонгнанского месторождения порфиров и эпитермальных отложений меди (Au), Центральный Тибет, Китай

The newly discovered Tiegelongnan Cu (Au) deposit is a giant porphyry deposit overprinted by a high-sulfidation epithermal deposit in the western part of the Bangong–Nujiang metallogenic belt, Duolong district, central Tibet. It is mainly controlled by the tectonic movement of the Bangong–Nujiang Oceanic Plate (post-subduction extension). After the closure of the Bangong–Nujiang Ocean, porphyry intrusions emplaced at around 121 Ma in the Tiegelongnan area, which might be the result of continental crust thickening and the collision of Qiangtang and Lhasa terranes, based on the crustal radiogenic isotopic signature.

Carrapateena is an underground sublevel cave operation. To maximise future value from the Carrapateena copper–gold resource, an expansion study has been completed to feasibility study level to assess a larger block cave expansion below the current sublevel cave. This paper will summarise Carrapateena block cave mine design and planning from pre-feasibility to feasibility study.

Mineral exploration is undertaken in stages, with each stage designed to get to the next decision point of whether or not to keep exploring a particular area based on the results at hand. As a general rule, each consecutive exploration stage is more expensive due to the progressively more drill- and study-intensive nature of the work required, in particular after discovery of a potentially economic mineral deposit.
