The platinum-group minerals (PGM) are a diverse group of minerals that concentrate the platinum-group elements (PGE; Os, Ir, Ru, Rh, Pt, and Pd). At the time of writing, the International Mineralogical Association database includes 135 named discrete PGM phases. Much of our knowledge of the variety and the distribution of these minerals in natural systems comes from ore deposits associated with mafic and ultramafic rocks and their derivatives (see also Barnes and Ripley 2016, this volume).

This guidebook is dedicated to ultramafic-mafic intrusions, volcanic rocks and the world-class PGE-Cu-Ni sulfide deposits of the Noril’sk Province, Polar Siberia. The characteristics of geology, mineralogy and geochemistry of volcanic rocks and ore-bearing ultramafic-mafic intrusions are briefly outlined. The proposed excursion stops include inspection of the different volcanic and intrusive rocks, associated PGE-Cu-Ni sulfide ores from drill cores and bedrock outcrops. In addition, an open pit Medvezhy Ruchei and two mines (Oktyabrsky and Taimyrsky) collectively provide an overview of the Noril’sk-type intrusions and associated disseminated and massive PGE-Cu-Ni sulfide ores.

Обогащенные PGE–(REE–Ti) элементами включения микрометрового размера, минеральные ассоциации, вариации состава и потенциальный источник минералов платиновой группы в россыпной зоне Сисим, Восточные Саяны, Россия.

We report the results of a mineralogical investigation of placer samples from the upper reaches of the Sisim watershed, near Krasnoyarsk, in Eastern Sayans, Russia. The placer grains are predominantly Os–Ir–(Ru) alloys (80%) that host various inclusions (i.e., platinum-group elements (PGE)-rich monosulfide, PGE-rich pentlandite, Ni–Fe–(As)-rich laurite, etc.) and subordinate amounts of Pt–Fe alloys.

This book describes extraction of nickel, cobalt and platinum-group metals. The starting point is ore-in-place and the finishing point is high-purity metals and chemicals.
We have combined the description of these metals in one book because they very often occur together, are extracted together and have similar properties.
The objectives of the book are to:

(a) describe how these metals occur and are extracted;
(b) explain why these extraction processes have been chosen;
(c) indicate how the processes can be operated most efficiently, with minimal impact on the environment; and,
(d) suggest future improvements.

Металлы платиновой группы это важнейшее стратегическое сырье, в связи, с чем потребность в их обнаружении представляет очень важную задачу для геологии. С каждым годом увеличивается потребность в золоте и металлах платиновой группы. К числу перспективных на благороднометалльное оруденение относится Центральный регион России. Необходимо развитие социально-экономического положения этого региона за счет увеличения минерально-сырьевой базы.

Большая часть мировых ресурсов элементов платиновой группы (ЭПГ) сосредоточена в малосульфидных месторождениях (Додин н др., 1999; Naldrett, 2010), локализованных лрсиму шестое шю в расслоенных базит-гипербазитовых массивах. За последнее десятилетие в раниепротсрозойских расслоенных массивах Кольского региона разведаны и поставлены на государственный баланс четыре месторождения, выявлены десятки малосульфных рудопроявлений платиновых металлов.
