Mining in Argentina is diverse in terms of the number of minerals extracted from the country, but also in terms of the varied approaches and attitudes of mining investors and their trust in the country's individual provinces. Laws are discussed, investment attractiveness and taxation.

At its peak in the 1970s, South Africa was responsible for around 80% of global gold production and, according to the US Geological Survey, it still has the largest share of gold reserves - as well as 90% of the world's platinum. But, in January 2015, gold production reached a new monthly low, generating 87% less than it did in January 1980, and South Africa is now the world's sixth ranked gold producer. What next for African gold?

The production of titanium dioxide (TiO2) from its minerals such as ilmenite is challenging, and subsequent isolation of titanium from TiO2 is even more difficult because of the metal-oxygen bond strength. Currently, titanium sponge is mainly produced via the Kroll process, which is energy intensive and generates large quantities of waste. A number of international research groups have come up with technologies for the production of titanium metal. However, none of them have been commercialised, because of engineering or economic issues. The team at Bradford have confirmed that ultra-pure titanium powders can be separated from TiO2 powder through metallothermic reduction and are working to scale up the process.

Mines are facing fresh challenges over how they deal with the huge quantities of water consumed. industry analyst Frost and Sullivan, demand for treatment equipment and services alone is expected to be worth US$3.6bn by 2016, while a report by consultancy Bluefield Research estimates that the total mine water market - which includes water infrastructure such as reservoirs, pipelines and dewatering systems as well as the equipment and services - will be worth US$17bn by the end of 2019. Methods of water decontamination are described.

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

Respect for mining in Botswana is long-standing. This article looks at Africa's most transparent mining regime and some of its ambitious plans. Botswana's mining industry value is forecast to average 5.2% growth from 2014-2018 with solid growth for the diamond sector and acceleration of coal production. Respect for the country's mining regime is maintained in the Fraser Institute 2014 annual survey where Botswana occupies the 26th position of 122 administrations. Botswana's transparency is illustrated by Mupane gold mine near Francistown, Ghaghoo diamond mine in the Gope area and the Morupule coal mine

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

Industrial minerals are extremely important to downstream industries and in our everyday lives. Their ontribution to the UK economy and to society as a whole is greatly underestimated. The industrial minerals sector is lacing increased pressures - environmental and competitive - both at home and abroad. These pressures are likely to increase. The Government, working in conjunction with the industry, can help the industry to meet these challenges. The role of Government is to establish a dialogue w ith the industry, to find out what its concerns are.and to ensure that these are taken into account in the draw ing up of policies that affect it. There is also a role for it in exploring, with industry, the linkages between environmental improvement and competitive advantage, and giving, w herever possible, early warning about regulatory developments. In order to maximise the effectiveness of links, industry needs to be coherently organised and represented both in the UK and in the European Union (EU).

This paper explores the potential to exploit controls over the outputs of the primary blasting operation, arising from the performance consistency benefits gained in using modern bulk emulsion explosives technology. The former, allied with the latest powerful blast predictive software and measuring tools, offers the user the opportunity to apply control over both cost and performance, which has not been possible in the past.

The most traum atic event within the lUK coal industry during the last 30 years was its privatisation. Who were the relatively unknown people from RJB: white knights or robber barons? This paper highlights the strong safety and progressive engineering cultures th at existed and continues within the company. A long-term view of the business coupled with proven professionalism is amply developed. Quite dearly, to revert to private ownership is not a return to Victorian values but ‘back to the future’.
