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...

due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. the known world class cu-mo deposit, sarcheshmeh porphyry deposit (central iran) selected as the study area. the hypogene zone of the deposit was chosen as the space in which estim...

Located on the west coast of Pacific Ocean, Jiaodong gold concentration area is one world's famous deposit areas. Its unique metallogenic environment and background are favored by geologists all countries, multi-level multi-disciplinary scientific research work has been carried out in this area, good results have achieved. Linglong deposit, located 20 km northeast Zhaoyuan, Shandong, a quartz v...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

introduction the mn mineralization occurs in the northeastern segment of the sabzevar zone (sz), north of the central iranian microcontinent (cim). this zone (sz) is located between the cim fragmentation in the south and the kopeh dagh sedimentary sequence in the north. the ore deposits of the northeastern segment of the sabzevar zone can be divided into three groups, each with different metal ...

Investigations on the chemical and microbial leaching of a Nigerian Iron-ore in sulphuric acid have been carried out. The influence of physico-chemical parameters such as acid concentration, temperature, particle size and stirring speed on the chemical dissolution of the ore was investigated. The dissolution rates are significantly influenced by the temperature and acid concentration while the ...

Abstract The Juomasuo Au–Co deposit, currently classified as an orogenic gold deposit with atypical metal association, is located in the Paleoproterozoic Kuusamo belt northeastern Finland. volcano-sedimentary sequence that hosts was intensely altered, deformed, and metamorphosed to greenschist facies during 1.93–1.76 Ga Svecofennian orogeny. In this study, we investigate temporal relationship b...

Sandstone-hosted roll-front uranium ore deposits originate when U(VI) dissolved in groundwater is reduced and precipitated as insoluble U(IV) minerals. Groundwater redox geochemistry, aqueous complexation, and solute migration are important in leaching uranium from source rocks and transporting it in low concentrations to a chemical redox interface where it is deposited in an ore zone typically...

A geometallurgical model was developed in three steps using the Malmberget iron ore deposit, northern Sweden as a case study. It is based on a mineralogical-particle approach which means that the mineral information is in the focus. Firstly, the geological model describes quantitatively the variation within the ore body in modal composition and mineral textures. Traditional geological textural ...
