Abstract The use of copper isotopes related to ore deposit location and genesis has greatly expanded over the past twenty years. isotope values in ores, rocks, soils, water range greater than 10‰ provide ample isotopic variation identify interpret complex geological process. From an exploration standpoint, waters, sulfides weathered rocks vector mineralization at depth. Ground surface waters di...

Abstract The ages of Zn-Pb deposits are exceptionally challenging to determine owing the lack suitable mineral chronometers and techniques. Here we present first result for in situ LA-ICP-MS U-Pb dating carbonates barite from a Mississippi Valley– type (MVT) deposit South China. Hydrothermal dolomite close textural paragenetic association with sulfides, calcite cement breccia ores, yield 473.4 ...

Through integration of Pb-Zn ± Cu non-sulfide mineralogy, texture, and stable isotope (C, O, S) geochemistry, the world-class Touissit- Bou Beker Jbel Dahar Mississippi Valley-type districts Moroccan Atlasic system have been investigated in order to gain insights into origin processes that contributed formation base metal mineralization. In both districts, direct replacement (“red calamine”) wa...

The rapid growth in the demand of embedded systems and the increased complexity of embedded software pose an urgent need for advanced embedded software development techniques. Software technology is shifting toward semi-automated code generation and integration of systems from components. Component-based development (CBD) techniques can significantly reduce the time and cost for developing soft...

In the south of Far East, a large deposit Sukhoe gold has been identified, where noble metal is in dispersed form, being present form microscopic particles, or entering structure sulfide minerals. It was found out that «invisible» (nano) finding mainly associated with pyrite and arsenopyrite. To develop technology for extracting useful component, completeness convenience opening stone material ...

Porphyry Mo deposits are the most important type of resource. They result from a high oxygen fugacity parent magma, which acts as an effective indicator for evaluating mineralization. In ore-forming system porphyry deposits, sulfur exists mainly sulfate in highly oxidized magma but sulfide ores. What triggers reduction mineralization that leads to precipitation has not yet been determined. Most...

This study assessed the radiological health hazards to various body organs of workers working within Transnet Precinct in Richards Bay in Kwazulu-Natal, South Africa due to radionuclide content of mineral ores often stored within the facility. Thirty samples were collected from five mineral ores (rock phosphate, rutile, zircon, coal and hematite) and analyzed for 238U, 234U, 226Ra, 210Pb, 235U,...

Dolomite [CaMg(CO3)2] is an intolerable impurity in phosphate ores due to its MgO content. As high grade phosphate reserves become depleted, the need to develop a cost effective method for the removal of dolomite from high-MgO phosphate ores becomes increasingly important. The jigging process has been investigated as a method for the beneficiation of high-MgO sedimentary phosphate ores. A labor...
