ABSTRACT Estimation of mineral resources and reserves with low values of error is essential in mineral exploration. The aim of this study is to estimate and model a vein type deposit using disjunctive kriging method. Disjunctive Kriging (DK) as an appropriate nonlinear estimation method has been used for estimation of Cu values. For estimation of Cu values and modelling of the distributio...

An expert system, for fault diagnosis of shaking table operations, is presented. The system is designed as one element of an integrated, computer-based method for plant enhancement, for application in the mineral processing industry. The relationship between expert and conventional software techniques is discussed. The system is based on prod uc tion rule s and has been wri tten in the PROLOGla...

-After moisture stress, one of the most important limiting factors for crop productivity is nutrient stress. The crop yield losses are estimated to an extent of 10-20% with or without-visual symptoms (“Hidden hunger”). Of the several nutrients, P, Fe, Zn, B & Mg are reported to be in short supply for plant growth and productivity globally. Especially the low level of Fe and Zn has a bearing on ...

introduction the senj deposit has significant potential for different types of mineralization, particularly porphyry-like cu deposits, associated with subduction-related eocene–oligocene calc-alkaline porphyritic volcano-plutonic rocks. the study of fluid inclusions in hydrothermal ore deposits aims to identify and characterize the pressure, temperature, volume and fluid composition, (ptx) cond...
