“…The requirements for the quality of crude ore vary due to considerable diff erences in the assessment criteria and the main methods for achieving the required quality parameters of the extracted ore. The development and practical implementation of an automated quality management system for mined ore in quarries contribute to the systematisation of all ore extraction processes and the determination of the quality of extracted crude ore at the early stages of its extraction, to optimise its subsequent processing and use [6].…”

Purpose. Formation of a realistic assessment of the prospects for the introduction of automated ore extraction systems and quality control in the activities of modern mining enterprises. Methodology. The basis of the methodological approach in this study is a combination of system analysis of various aspects of automation of management processes of ore quarrying, with an analytical investigation of the prospects for optimising ore mining processes in quarries using modern methods of automation and digitalisation. Findings. A systematic analysis of various aspects of automation of ore mining management processes by quarry method was performed. The most promising areas of quarry development in order to obtain ore raw materials of the highest quality were identified. A scheme showing the systems of methods for managing the quality of ore mined by the mining method at the mining enterprises was presented. In addition, the scheme of automation of ore quality management processes extracted in quarries was presented and analysed. Originality. A real assessment of the prospects for the introduction of automated systems of ore mining and quality control in the activities of modern mining enterprises has been formed. Practical value. The results of the research can be used as a basis for training specialists in the field of mining industry, whose professional responsibilities include solving issues of ore mining in a quarry way.

A geochemical study over the southwestern part of the South Range of the Sudbury Igneous Complex (SIC) was completed to assess the suitability of surficial media (humus, B-horizon soil and C-horizon soil) for delineating geochemical anomalies associated with Ni-Cu-PGE mineralization. Another objective was to test whether Na pyrophosphate can eliminate the effects of anthropogenic contamination in humus. Results of this study suggest that the natural geochemical signature of humus is strongly overprinted by anthropogenic contamination. Despite no indication of underlying or nearby mineralization, metal concentrations in humus samples by aqua regia collected downwind from smelting operations are higher compared to background, including up to 13 times higher for Pt, 12 times higher for Cu and 9 times higher for Ni. The high anthropogenic background masks the geogenic signal such that it is only apparent in humus samples collected in the vicinity of known Ni-Cu-PGE deposits. Results of this study also demonstrate that anthropogenically-derived atmospheric fallout also influences the upper B-horizon soil; however, lower B-horizon soil (at > 20 cm depth) and C-horizon soil (both developed in till) are not affected. Glacial dispersal from Ni-Cu-PGE mineralization is apparent in C-horizon till samples analyzed in this study. Compared to the background concentrations, the unaffected C-horizon till samples collected immediately down-ice of the low-sulfide, high precious metal (LSHPM) Vermilion Cu-Ni-PGE deposit are enriched over 20 times in Pt (203 ppb), Au (81 ppm) and Cu (963 ppm), and over 30 times in Ni (1283 ppm).Supplementary material:https://doi.org/10.6084/m9.figshare.c.5691080

Since the 1970s, till geochemical and indicator mineral methods for mineral exploration, provenance studies and environmental research in glaciated terrain have been developed, tested, and refined. This paper summarizes these methods, focussing on field and laboratory methods for till geochemical, indicator mineral, and boulder surveys. This review of protocols is meant to be a guide for the mineral exploration industry and publicly funded agencies. The paper summarizes till as a sample medium, describes the formation of glacial dispersal trains, and methods for till sample collection, sample processing, matrix geochemistry, indicator mineral analyses, quality assurance/quality control (QA/QC) procedures, and data reporting and interpretation. The methods described here can be used to conduct reconnaissance- to deposit-scale till sampling surveys to assess mineral resource potential and establish environmental baselines.
