The use in regional geochemical reconnaissance of replicate analysis of natural coatings of iron and manganese oxides on the surface of pebbles in stream sediment is described. Pebble coatings were selectively analysed for their relative contents of absorbed trace elements by ablating a small quantity of the coating with a laser beam and sweeping the aerosol obtained into an inductively coupled plasma atomic emission spectrometer. Using this procedure, a geochemical survey in northwest Wales revealed anomalous concentrations of Cu, Mo, As, Zn, Cd, Pb and Co in the pebble coatings of streams draining the mineralised Coed-y-Brenin diorite and the Dolgellau gold belt.

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 reduction of naturally weathered ilmenite concentrate occurs in two steps: reduction of Fe3+ to Fe2+, followed by reduction of Fe2+ to Fe. Small amounts of a magnetic phase were also observed and may correspond either to an Fe3O4-FeTiO3 ilmenite phase or to an Fe3O4-Fe2TiO4 spinel phase. The total amount of metallic iron produced after 12 hr was only 50% of the total iron present in the sample.

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

Complete extraction of copper from Salobo chalcopyrite concentrate can be achieved in less than 10 minutes by chlorination of the dry concentrate with Cl2 at 450 degrees C and in 5 minutes by chlorination of an aqueous slurry containing 5 wt% concentrate at 30 degrees C. In general, slurry chlorination appears to be faster than dry chlorination. The kinetics of dry chlorination of copper sulphide are controlled by an adsorption mechanism with an activation energy of 6.1 kcal/mole. The rate is independent of chlorine partial pressure when pCl2 exceeds 0.4 atm. In slurry chlorination the dissolution of copper sulphide follows a topochemical reaction model and the rate of chlorination decreases with increase in pulp density and also temperature. Dissolved chlorine appears to take part in the reaction in atomic or ionic form.

Although copper has been smelted for many years, relatively small attempt has been made in the past to examine the fundamental physical chemistry of the processes involved. Therefore, technological developments apart, slow progress has been made with the development of improved or new principles of smelting. The methods at present in use in the majority of the world’s smelters are essentially those employed at the beginning of the present century; it is significant that many of the textbooks on copper smelting, written some 50 years ago, are still regarded as standard works. The book is divided into seven chapters. In the first the fundamentals of modern smelting processes are briefly outlined for easy understanding of the subsequent sections, while the next two chapters are confined to the more theoretical aspects of the constitution of mattes and slags. Some problems of considerable practical importance are discussed in the remaining four chapters; these are (1) magnetite formation, (2) copper losses during smelting, (3) the recovery of sulphur from the smokes produced during smelting, and (4) the elimination of impurities. A collection of thermodynamic data relevant to copper pyrometallurgy is presented in an appendix, and, for the convenience of readers not well acquainted with thermodynamics, a brief explanation of the thermodynamic terms and methods employed is given in a second appendix

Paper presented at the IAGOD international symposium on mineralisation related to mafic and ultramafic rocks held in Orleans, France, 1-3 September 1993. The massif contains large chromite bodies of "Alpine-type", ophiolitic affinity. Orebodies reach thicknesses of 150 m and sizes of more than 150 000 000 t chromite ore with average grades of 55-60 wt% Cr2O3. Chromites in the Main ore field are low-Al, high-Cr spinels which exhibit some variation in their Mg-Fe distribution. This differs markedly from high-Al spinels in peridotite host rocks and in narrow chromite pods which occur in the western and northern parts of the massif. Chromites carry silicate inclusions, often hydrous silicates such as amphibole. Chromites in massive chromitites contain micron size inclusions of platinum group minerals (PGM). Composite grains containing two PGM and, occasionally, a hydrous silicate are common. Os-Ir alloys rimmed by PGM sulpharsenides occur in narrow serpentine veinlets that cut chromite and are evidence for the reconcentration of PGE concomitant with introduction of As, probably during serpentinisation. Whole-rock PGE contents are highest in massive chromitites of Diamond Pearl mine (totals of 500 ppb). Chondrite-normalised PGE patterns of chromitites show negative slopes which are typical for ophiolitic, podiform chromitites in mantle sequences. The PGE patterns of host rocks are flat and rather depleted compared with those of chondrites and chromitites. Petrological data from unaltered host peridotites suggest a high temperature overprint leading to sub-solidus re-equilibration of olivine and spinel and to the growth of pargasitic and edenitic amphiboles

Paper presented at the 28th International Geological Congress held in Washington DC, July 1989 (International geochemical mapping sessions). Evidence is accumulating that reconnaissance-level biogeochemical sampling can provide valuable insight into the chemistry of the substrate. Problems such as seasonal variations in plant chemistry and the lack of a universal biogeochemical sample medium may be circumvented by adopting normalising procedures. The planet can be divided into a few climatic zones, each of which is characterised by one or two common plant genera. If it can be demonstrated that the chemical differences between certain species of a single genus are small - as is suggested by studies of boreal forests - it would seem feasible to apply biogeochemistry as a low-density geochemical mapping tool. The technique could prove particularly useful for assessing the substrate chemistry of areas of dense forest, rugged terrain and difficult access by employing airborne sampling of trees from helicopters
