In northern Vietnam Ni-Cu sulphide deposits associated with ultramafic rocks are located in several continental rift zones of Permo-Triassic age. In recent years a number of ultramafic bodies have also been discovered in southern Vietnam, but detailed work on sulphide occurrences within these bodies has still to be undertaken. A brief description is given of some N i-C u sulphide deposits that are located in the northern part of the country. Of the depos­ its that have been examined in any detail, those in the Takhoa region are of the greatest economic interest. Ni and Ni-Cu sulphide bodies have, however, also been found in association with the ultramafic rocks.

It is shown that sodium can be removed very readily from molten aluminium by the use of a beta"-alumina, the more highly conducting form of beta-alumina, provided that the surface of the tube is wetted by a layer of salt. From current/time plots the theoretical amount of sodium removed has been calculated and excellent agreement obtained. The beta"-alumina tubes can be immersed directly in the Al without fracturing if they are pre-heated for a few minutes prior to immersion. According to its stability beta"-alumina should be attacked by molten Al at low Na contents, but in these experiments the salt acted as a protective layer. Magnesium chloride is a relatively cheap salt, whose Mg product can be used within a foundry. The only other product is NaCl, which can be used in-house as a flux or sent for disposal. No polluting gases are used or produced and no drosses created. The time for removal of sodium was quite short, comparable to that for chlorination

Strong disagreement is registered by A.A. Rocha Gomes with Leca's account of the discovery published in Trans. IMM B, vol.99, 1990, p.B139-B152, which he contends minimises the role of the Portuguese state organisation Servico de Fomento Mineriro (SFM); the author, in response, once again thanks all SFM staff but reiterates his conclusion that Neves-Corvo was discovered through an amalgamation of exploration results and interpretations from different sub-disciplines and geoscientists

The Minister for Roads and Traffic's opening speech highlights some of the topics to be covered in the conference with particular reference to the Channel Tunnel, the recent breakthrough of whose service tunnel marked a historic moment three and a half years after passing of the Channel Tunnel Act and which was the first example in recent years of a major transport project entirely privately funded. The Minister also mentioned the building of UK road tunnels, research and development, and the role of UK consultants in the single European market

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).
