The present research paper deals with the oxidation process of molybdenum ore. The main target of the present study is the up-gradation of MoO3 from roasted molybdenum ore by a leaching process without waste generation. The most important application of hydrometallurgical processing is the leaching process of the ore and it is the primary process to make pure metal from ore. The present investi...

A typical South Crofty ore containing minor amounts of arsenopyrite and chalcopyrite (ore A) gives 65% overall recovery of cassiterite in the spiral circuit, overall enrichment ratios being about 25-35. Maximum recovery occurs in the size range 53-110 /Lm(Fig. 2). However, recently treated ore types (ore B) have been much richer in sulphides, yielding up to 30°" As in the recleaner table concen...

A double Ore extension is a natural generalization of the Ore extension. We prove that a connected graded double Ore extension of an ArtinSchelter regular algebra is Artin-Schelter regular. Some other basic properties such as the determinant of the DE-data are studied. Using the double Ore extension, we construct 26 families of Artin-Schelter regular algebras of global dimension four in a seque...

Mineral liberation is an important variable to be considered in the iron ore geometallurgical studies, especially since it provides information leading understanding of ore’s behaviour beneficiation process, mainly when harder ores are concerned. Nowadays, professionals and researchers mineral industry have been using complementary techniques for mineralogical characterization. In this way, Lib...

Abstract Trace element changes in fluids associated with ore-forming events sedimentary basins may be recorded by contemporaneous cements, especially zoned carbonate minerals (microstratigraphy). Cement analysis using advanced mapping and analytical techniques including scanning electron microscopy cathodoluminescence (SEM-CL), charge contrast imaging, high-resolution X-ray computed tomography ...

The current research on metallurgical remains from scientific excavations in northeast Yunnan the Bronze Age period is insufficient. In order to study smelting technology of north-eastern Yunnan, samples slag and mineral excavated Yubei Di site Dongchuan were examined. Based outcome characterization analysis, a simulation was executed utilizing software Factsage 7.1 generate phase diagram that ...

The present work analyzes the specimens of orthite (allanite) mineral ores obtained from Vernadsky mine (Slyudyanka River, Irkutsk region) and Yuzhno-Bogatyrskoye occurrence (Kuznetsk Alatau). elemental chemical composition ore was determined by electronic microscopy specimen’s surface. study establishes that uranium thorium in are mainly represented their separate minerals, while content phase...

A simple and easy-to-use miniphotometer has been designed; the expense involved amounts to only a fraction of that required for large commercially available microphotometers. The instrument can be employed for routine investigations and for teaching reflected light microscopy in conjunction with standard reflected light microscopes. The reflectance of grains down to 50/xm size can be measured i...
