Sieving & Granulometric Separation of Granular or Clay-Bearing Materials

Classical apparatus for granulometric separation generally have limited applications which are found either in the level of the size of separation or in that of the accuracy and the efficiency of the separation or in that of the rate of feed. Principles and Description of the Sieving – Panel The study of the problems of … Read more

Aqua Regia-Extractable Versus Total Copper and Zinc Content of Granitic Rocks

One of the analytical problems in exploration geochemistry is the choice of a method of sample attack which would be rapid, simple and reliable in terms of precision and discrimination between different concentration levels of elements sought. The wet sample attacks currently used in analysis of silicate rocks vary from total decomposition to leaching by … Read more
