Commodity prices are characterized by boom and bust cycles. In this article, the impact of the commodity boom of the 2000s on Latin American and Caribbean economies is studied by analyzing four categories of commodity exports (agricultural raw materials, fuel, food, ore and minerals) as well as manufactured exports. Latin American and Caribbean economies had higher growth during the 2000s than ...

In this paper we present a novel Point-based pattern analysis for predicting Cassiterite (tin-ore) as a secondary mineral deposit in the Plateau Younger Granite Region of Nigeria (PYGR) using statistics, spatial analysis and machine learning techniques. Existing mining data points collected from field survey in the PYGR and the geological map of the region were digitized and converted into shap...

Two texturally and mineralogically distinct types of Mississippi Valley-type mineralization are hosted by the upper Cambrian Metaline Formation in northeastern Washington. Josephine-type mineralization is iron poor and coarse grained, whereas Yellowhead-type mineralization is iron rich, fine grained, and commonly botryoidal. Josephine mineralization is found largely in the Josephine lithofacies...

It is vell known that fines and ultrafines can cause severe problems in mining and mineral processina. The decrease in the grade of ore combined with the arowinS demand for aineral products baa led to the minina and milling of increasing tOQnage or ore. Cl08ely linked with the problem of reduction in the grade of ore is. the more serious problem of the decrease in libration size. A direct cODsq...

barika gold (and silver) rich massive sulfide deposit is located 18 km east of sardasht, north western part of sanandaj-sirjan metamorphic zone. rock units outcropped in this area are cretaceous metamorphosed volcano-sedimentary rocks in green schist facies, and include association of meta-andesite, meta-tuffite, phyllite and slate rocks, where the meta-andesitic unit (kmv1) is host rock to the...

This paper provides a review of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Advanced Land Imager (ALI), and Hyperion data and applications of the data as a tool for ore minerals exploration, lithological and structural mapping. Spectral information extraction from ASTER, ALI, and Hyperion data has great ability to assist geologists in all disciplines to map the d...

The associated mineral ore accompanying Valuable Metal Compounds (VMC) have been usually treated in a smelting furnace ,such as Blast Furnace, Reverberatory, Blowing Furnace, hence the VMC were mostly concentrated into the molten associated slags and separated from liquid metals. So the associated slags become an important man-made resources (Table I), in which the VMC exist dispersively in var...

Broadband frequency-domain electromagnetic sensors can be used not only to detect but also to characterize and identify a particular mineral deposit based on its spectral response. The concept is similar to identifying a particular landmine based on its unique spectral response, which is known as Electromagnetic Induction Spectroscopy (EMIS). Recent advances in single-coil, broadband sensors ha...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...
