Following on from the article in Materials World February 2015 (Asset 997) this article is the second half of a special focus on graphite. It looks at graphite's market prospects over the next few years. Natural graphite is used in refractories, which accounts for ca. 20% of global demand and is forecast to grow by 2-4%/a to 2020, while the largest growth in demand (increases of 10-15%/a) is estimated to come from its application in anodes for lithium-ion batteries, especially those in hybrid electric vehicles. High-grade natural graphite deposits that are either coming back on stream or are in the pipeline are discussed including Woxna mine in Sweden, Bissett Creek project in Ontario, Canada, Balama mine in Mozambique and Lac Knife project in Quebec, Canada

Application of the Internet of Things (IoT) technologies - the interconnection of uniquely identifiable embedded computing devices within the existing internet infrastructure - to the mining industry is discussed. IoT technologies are aimed at making projects safer, better optimised and more economic and are applicable to current or new underground or open-pit mines, regardless of size. Two examples are presented of successful implementation of IoT technologies, the Chelopech gold, copper and silver mine in Bulgaria, where production has increased from 500 000 to 2 000 000 tonnes/y and communication costs have been reduced by US $2 500 000 over 2 y, and the Pilbara project in Western Australia, where remotely controlled wirelessly connected autonomous trucks have covered ca. 3 000 000 miles and hauled almost 250 000 000 t of ore since 2008

The current status of the heavy and light rare-earth elements outside China is reviewed. New suppliers of the light rare-earth elements are Lynas (Australia/Malaysia) and Molycorp (USA), which are anticipated to process 11 000 and up to 10 000 t/y, respectively, and the most advanced heavy rare-earth elements project is Avalon's Nechalacho project at Thor Lake, Northwest Territories, Canada. U3O8 Corp has potential rare-earth elements production, e.g. ytrrium and neodymium, from its Berlin deposit in Colombia and Namibia Rare Earth's Lofdal project (Area 4) has potential to produce an average of 1 500 t/y of separated rare-earth oxides. With regard to the three historical producers, India has some small-scale production, Brazil has been a small-volume producer and has potential for new heavy rare-earth elements production, while South Africa has no current production

IMAGES (Integrated Mapping Applications Graphical Evaluation System) is a computer graphics system developed by British Coal for mine planning. The objectives of the system are to increase the profitability of mined coal through a combination of direct and indirect benefits. The system is flexible and can be used in part or in full at a mine as a stand-alone system or as a remote location of a central corporate system.

"This paper summarises many experiments conducted, and how in North American industry the use of aluminium in treatment and prevention has been adopted widely. The Pottery Insurance Co., Ltd., made it possible for me to investigate conditions in Canada and the U.S.A., and I thank them for permitting me to submit this short paper- an abstract of my report to them."

Two of the most important economies in coal-washing are in the actual washing of the coal and in a proper lay-out to reduce to a minimum the cost of labour for handling and washing. A guarantee is usually required for turning out a washed coal containing not more than 2% of free dirt and a resulting refuse with not more than 2% of free coal; any plant that gives results within such guarantees can he considered economical, provided that there are no other losses during the washing process. Various drainage arrangements and washery lay-outs are illustrated and discussed with respect to drainage, bunkers, sieves, settling tanks and conveyors and two further points considered: siding accommodation, which may become quite important with washeries of large capacity especially when the coal is brought in railway-wagons; and the irregularity with which the coal arrives.

This paper describes the history of civil engineering tunnelling and developments in soft ground techniques during the 19th and 20th centuries, culminating in the design and use of high speed tunnelling machines for all types of ground conditions. Some of the problems encountered are outlined, and descriptions are given of some contemporary developments in rock tunnelling techniques, with comparisons of methods used in the mining industry.

During the production of the Geochemical Atlas of Finland till samples were collected throughout Finland at a density of one sample per 300 km2. The material studied was the fine fraction of till (less than 0.06 mm). The geochemical mapping has shown that elements that are locally enriched in bedrock in the form of ore mineralisation are also enriched in a wide area of the surrounding till. These anomalous enrichments of ore elements take the form of rectangular or curvilinear zones that are some tens of kilometres wide and hundreds of kilometres long. The mineralised zones host ore deposits of different genetic types and can be termed "ore provinces". They stand out prominently on the geochemical maps and can be divided into sub-units of different chemical composition.

"The paper covers the activities of the Government Miners' Training-Schools. It argues that its success is proved by the steady demand for miners trained at the Schools; by the large numbers of ex-apprentices who hold responsible official positions in the industry; and bv the probable expansion of the organization in the near future to meet the never-ending call for trained personnel."

A personal overview and assessment is given of the 42 papers delivered over the three days of the symposium. As well as 18 from the UK there were presentations from 16 other countries; 20 were on rock tunnels, 13 on soft ground and 3 on both; there were 17 case histories and 16 discussions of tunnelling machines but, for the first time in the conference series, almost no papers on tunnelling for mining purposes. Some projects, such as the Lesotho Highlands Water Project and the London Ring Main, attracted a number of papers addressing their different aspects
