The term rare earths denotes the group of 17 chemically similar metallic elements that includes scandium, yttrium, and the lanthanides (Spedding 1978; Connelly et al. 2005). The lanthanides are the series of elements with atomic numbers 57 to 71, all of which, except promethium, occur in nature. The rare-earth elements, being chemically similar to one another, invariably occur together in minerals and behave as a single chemical entity. Thus, the discovery of the rare earths themselves occurred over a period of nearly 160 years, from 1787 to 1941 (Szabadvary 1988; Weeks 1956).

This book is written as a practical field manual to be used by geologists engaged in mineral exploration. It is also hoped that it will serve as a text and reference for students in Applied Geology courses of universities and colleges. The book aims to outline some of the practical skills that turn the graduate geologist into an explorationist:. It is intended as a practical 'how to' book, rather than as a text on geological or ore deposit theory. An explorationist is a professional who searches for ore bodies in a scientific and structured way. Although an awkward and artificial term, this is the only available word to describe the totality of the skills which are needed to locate and define economic mineralization.

In early August 2012, following failed wage negotiations and civil unrest, about three thousand striking platinum miners employed by Lonmin plc gathered on a hill close to the town of Marikana in the North West province of South Africa. Nine out of ten Lonmin miners were migrants, mainly from the Eastern Cape, who lived next to the mine in squalid shacks and informal settlements.1 During a confrontation on 16 August, police opened fre, wounding 78 miners and killing 34 others. Many of those killed and injured were shot in the back.

It is necessary to define some fundamental terms that will provide indispensable background for the entire book. The first term to be explained deals with the title of the book: mineral resources. A mineral resource can be defined broadly as the concentration of material of economic interest in or on the Earth’s crust. In this book, it includes solid earth materials such as metals (i.e., copper, gold, iron),

Mine designers often face difficulties in selecting an appropriate mining method; however, such a method should be selected based on ore and rock characteristics. The selection of mining methods can be considered a type of multi-criteria decision making, and this depends on many factors used in the selection process.

Mining method selection is the most fundamental activity of a mining study, because everything else depends on it. It is a process whereby the mining method attributes are matched to the orebody characteristics. This crucial decision must invariably be made at a stage of the study when the least information is available.

Рассмотрено оборудование, применяемое при добыче полезных ископаемых открытым способом: буровые и шнекобуровые машины, одно- и многоковшовые экскаваторы, бульдозеры, рыхлители, скреперы, одноковшовые погрузчики, машины для гидромеханизации и драги.

Даны основные сведения по силовому оборудованию, технике безопасности, автоматизации рабочего процесса.
Учебник предназначен для студентов высших учебных заведений, обучающихся по специальности «Горные машины и оборудование» направления подготовки дипломированных специалистов «Технологические машины и оборудование».

This monograph provides a useful review of economic, financial and policy issues affecting the minerals industry and has proven extremely popular with students, practitioners and industry advisors. This second edition is timely given the continued high demand and interest for minerals professionals wishing to keep abreast of current thinking on this subject
The volume is set out in five main sections: Minerals and the World Economy Minerals - Consumption, Production and Markets Mineral Finance and Investment Minerals and Public Policy Mining and Local Communities
