Many problems occur in recruiting staff to remote mining operations, relating to both domestic and works environments. These are stated, together with steps which have been taken to overcome them. Geographical and climatic conditions applying to the Agnew mining operation are described. Company policies have been established to define criteria for selection of staff, and to define methods by which the criteria are applied.

Selecting persons who are unlikely to suffer an overexertion injury is one of three methods to reduce the risk of musculo-skeletal disorders in manual material handling. This paper describes the underlying models, methods, and techniques for such personnel selection. In particular, it describes the isoinertial LIFTEST in which persons actually lift weights to assess their capability for doing so on the job.

Introduction In difficult times such as these, there is a strong reaction to the current way of doing things. Typical reactions that we have all heard are "There has to be a better way," "We're pricing ourselves out of business," "We have to improve our productivity," and "We have to have more cooperation," between union and management and employees and management. All of these comments have at their roots one common factor - getting the maximum amount for your dollar. The other factor inherent in these statements is productivity. I have not yet met a person in our industry who has not expressed the opinion that we should, and that we can, improve our productivity. Reducing Labor Costs In light of these factors I suspect we have all spent a fair amount of time examining our labor costs. For some of us, labor costs are a high proportion of our total cost of doing business. To alleviate the impact of these costs, we have generally done four things. We have reduced our number of employees, shut down operations for appropriate periods, sought concessions from union employees, and placed freezes on wages, salaries, and other benefits on nonunion employees. These approaches have been made to improve current shortfalls in our cash positions - to tide us over, as it were - or to provide us with a chance for survival. These are short-term measures that help to bring immediate relief, but can pose significant problems (or challenges), for the longer term. For instance, what do we do when times improve? How much do things have to improve before we do anything? By seeking concessions from unions in bad times, what do we do when unions come to us in good times? It is a rather sad and critical fact that we have grown too fat during the good times and too thin during the bad. In the first case, we have failed to optimize our earnings. In the second, we have cut ourselves too far. Consequently, when good or better times have arrived, we have had to bulk up our requirements to meet production commitments. In mining, for example, when times become tough, we tend to reduce our development plans so that when times improve we have to really "sock it to 'em," so that we can maintain productive capacities. We should plan ahead a little more to reduce the amplitude of our cyclical wavelength, so that in good times profits are optimized and in bad time we are better able to take the strain. Of course, forecasting cycles is not a refined art, but if we properly control our work force levels and costs at all times, and therefore optimize our productivity, we would be more able to withstand the problems we face today. Unfortunately, it appears that it takes bad times to bring us to a realistic appraisal of our way of managing our businesses. Labor Practices Not all of the problems now faced are due to low metal prices. Inflation has played a major role in bringing costs to a frightening level. Trade unions alone can not be blamed for high inflation levels over the past several years, popular though that notion is. Contract negotiations, after all, require two parties. Indeed, our current levels of labor cost are due to two factors: • We have felt obliged to keep our employees whole, relative to the cost of living. • We have felt obliged to maintain our competitive position relative to our peers, in order to maintain our ability to attract and retain a skilled, efficient work force. In the first case, our felt obligation has been applied without due recognition of the factor of performance, either in individuals or groups. Average, even mediocre performers, have been amply rewarded for their average work and mediocrity, while the good performers, no doubt receiving more for their good work and effort, have not perhaps appreciated the slight premium for their effectiveness. The rather predictable result of this practice has been that the average and mediocre stay that way (why change?), while some (certainly not all) of the good performers have said "It's not worth it," and slipped into the warm, cosy pool of the average and mediocre. In the second case, that of maintaining competitiveness with other companies' employees, we have compounded an already serious problem of lack of skilled tradesmen by paying higher and higher prices for the existing pool to maintain comparability without improving the flow of more skilled people through sound and sufficient training programs. We have the rather dubious pleasure of paying more and more for the same problems. Compensation is either mutually agreed, as with unions, or it is unilaterally applied, as with nonunion employees. Generally, there is more flexibility available to the employer when dealing with nonunionized groups than there is with unionized groups. Sometimes that flexibility has not been used well, most often be-

El presente texto señala la dotación del cobre en el Perú desde el período 2013, la cual se encuentra ubicada en tres franjas metalogenéticas como son: Paleoceno, Eoceno-Oligoceno y Mioceno. Estas franjas produjeron más de 24 Mt de cobre y aún guardan reservas y recursos que llegan a 192 millones de toneladas. En ese sentido, el futuro de la producción de cobre se encuentra en 18 proyectos mineros, los cuales bajo un escenario optimista ingresan en producción entre 2014 y 2019. Para realizar este trabajo, se ha considerado datos estadísticos de producción global de cobre de la United States Geological Survey, y de la producción nacional de anuarios mineros del Ministerio de Energía y Minas el Perú hasta el año 2013. Los datos de reservas y recursos de operaciones y proyectos se han tomado de reportes anuales de compañías mineras y de exploración en el Perú.

El presente texto describe las perspectivas en la utilización de la tecnología de conversión del carbón en los países latinoamericanos para producir petróleo sintético y derivados. En ese sentido, el proceso de gasificación carbón y síntesis en combustibles líquidos es costoso. Por ello, se requiere un análisis económico cuidadoso antes de decidir la instalación de cada planta en los países en América Latina y en el que los institutos geológicos y del carbón de los países de Latinoamerica inicien o continuen, según sea el caso, con la exploración de los recursos carboníferos para determinar reservas, incluyendo las de los carbones hidrocarburables.

Nos últimos anos ocorreu uma deterioração considerável na qualidade química e granulométrica dos minérios de ferro utilizados na sinterização. Como resultado ficou limitada a utilização de silicatos de MgO na mistura, devido à elevação excessiva do teor de sílica no sínter, e as siderúrgicas voltaram a utilizar a dolomita como fonte de MgO. A utilização de pellet feed na mistura a sinterizar (natural ou moído) tem se apresentado como uma alternativa à elevação do teor de sílica na sinterização e a eventual redução na produtividade, compensada pela otimização das condições de misturamento. Testes em escala piloto indicam que a eventual redução na produtividade, decorrente da utilização do pellet feed, pode ser compensada pela utilização de olivina na mistura a sinterizar, em substituição à dolomita, com uma otimização do processo e da qualidade do sínter.

El proceso de industrialización del Perú se rige por la demanda de materias primas minerales, para las cuales se exigirá una óptima calidad y precios competitivos. Para contrarrestar esta demanda, es necesario el manejo adecuado del aprovechamiento de los recursos minerales naturales en los yacimientos mineros y así valorar las disponibillidades de los mismos a escala nacional. En este sentido, el objetivo del texto describe la aplicación del programa de no-metálicos que el Departamento del mismo programa INGEMMET propuso.
