The main purpose of geometallurgy is to develop a model to predict the variability in the mineral processing performance within the ore body. Geometallurgical tests used for developing such a model need to be fast, practical and inexpensive and include as an input data relevant and measureable geological parameters like elemental grades, mineral grades and grain size. Important in each geometal...

One of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. After choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. Choosing a mining method depends on the geological and geometrical c...

Mine valuation can be defined as the process of determining the worth of a specific mineral deposit and capability of making a return by a prospective investment (SME, 2005). Although the definition is very brief and compact, actually, it has a very wide content. Determination of worth of an underground asset requires a plenty of works to explain physical, structural and economical properties o...

the aim of the study is to determine the major source and extent of metal pollution in the vicinity of dashkasan gold mine. dashkasan mine has resulted in extensive contamination of soils by arsenic (as) and potentially toxic ore-related elements including mercury (hg), antimony (sb) and cadmium (cd). soils samples were collected and analyzed for as, cd, hg, pb and sb. the concentration of each...

Nowadays, shovels play an important role in production of open pit mines and their failures result in significant production loss and considerable increase in maintenance costs. Therefore, reliability and risk analysis can help to improve production, productivity and reduce production costs. In this study, reliability of electric cable shovel of Chadormalu iron ore mine in Iran was investigated...

A dynamic simulation algorithm based on 1-D transient convection/diffusion transport per particle size class is proposed to simulate a hydraulic classifier operated selectively remove quartz from an iron oxide concentrate produced by processing the ore mine in northeastern Canada. The calibrated model used operation of dense bed classifiers different sizes and/or under operating conditions. sim...
