This study describes a method used to improve ore grade estimation in a limestone deposit in India. Ore grade estimation for the limestone deposit was complicated by the complex lithological structure of the deposit. The erratic nature of the deposit and the unavailability of adequate samples for each of the lithogical units made standard geostatistical methods of capturing the spatial variatio...

Kazakhstan possesses the world’s largest resource base of proven industrial uranium reserves. The article discusses geological features and provides a theoretical justification for technology in-situ leaching (ISL) deposits in Republic Kazakhstan. Explored reserves amount to about 1 million 560 thousand tons uranium. presence significant reserves, well-explored deposits, well-developed mi...

Spatial fluctuations for in situ flow structures tend to be spatially highly erratic and to scale with physical dimension. Such reservoir flow spatial fluctuation properties are reflected in the lognormal distributions of well productivities in some oil/gas and geothermal fields. Ability to efficiently recognize and manage large-scale spatially erratic flow structures when they are present is t...

gomish-tappeh zn-pb-cu (ag) deposit is located 90 km southwest of zanjan, in northwestern part of urumieh-dokhtar volcano-plutonic zone. exposed rocks at the area include oligo-miocene volcano-sedimentary and sedimentary sequences as well as pliocene volcano-plutonic sequence (andesite porphyry dykes, dacitic subvolcanic dome and rhyodacitic volcanics). alteration in the deposit developed as si...

In this paper, we study linear control systems over Ore algebras. Within this mathematical framework, we can simultaneously deal with different classes of linear control systems such as time-varying ordinary differential systems, differential time-delay systems, partial differential equations, multidimensional discrete systems, etc. We give effective algorithms which check whether or not a line...

Development and implementation of large-scale industrial projects in complex eco-epidemiological settings typically require combined environmental, social and health impact assessments. We present a generic, spatio-temporal health impact assessment (HIA) visualization, which can be readily adapted to specific projects and key stakeholders, including poorly literate communities that might be aff...

Herein a big Fe-C-Ca cycle, clarifying the basic element flows and energy flows in modern carbon-intensive industries including the metallurgical industry and the cement industry, was proposed for the first time in the contexts of emission reduction and iron ore degradation nowadays. This big cycle was focused on three industrial elements of Fe, C and Ca and thus it mainly comprised three inter...
