soil contamination in the vicinity of the abandoned lakan lead and zinc mine was studied. the results showed that over the past decades, the environmental pollution was caused by lead, zinc tailings dam and acid mine drainage. the average of lead, zinc, cadmium, copper and nickel is 1295, 4273, 27, 185 and 92 mg/kg, respectively in the soils of tailings dam. these metals were continuously dispe...

One of the main tasks to analyze and design a mining system is predicting the behavior exhibited by prices in the future. In this paper, the applications of different prediction methods are evaluated in econometrics and financial management fields, such as ARIMA, TGARCH, and stochastic differential equations, for the time-series of monthly copper prices. Moreover, the performance of these metho...

The article describes the development and application of a new discrete time-event simulation modeling methodology used in the copper mining industry in Chile. The proposed methodology creates a simulation model that represents a mine-mill operation, and it is used to evaluate different improvement options to maximize the system performance. Two applications of this methodology to existing copp...

Abrud river is an aquatic ecosystem exposed to anthropogenic influences exerted by long-term mining. This study examines the level of copper concentrations by assessing both total copper content and ionic forms in surface waters and sediments. These components were studied in 10 control sites located in a section of river that has been exposed to acidic mine water spills and leaks. The partitio...

The mining industry is looking forward for bacterial consortia for economic extraction of copper from low-grade ores. The main objective was to determine an optimal bacterial consortium from several bacterial strains to obtain copper from the leach of chalcopyrite. The major native bacterial species involved in the bioleaching of sulphide ore (Acidithiobacillus ferrooxidans, Acidithiobacillus t...

Background: High concentrations of various heavy metals of mine tailings can easily contaminate the environment. Such materials need monitoring and remediation to prevent them from polluting the environment and food chain. Materials & Methods: The concentrations of certain metals were evaluated in the soil samples at Sorkheh and Mazraeh copper mining areas in northwestern Iran, using three r...

Technological procedure of extracting metals is being constantly modernised so that polluting of the basic life resources is reduced. Emissions of waste gases and particulate matter are still present in larger mining-metallurgical complexes. Mining-metallurgical complex Bor (RTB) exploits sulphide copper ores, thus emitting acid sulphur gases and suspended particles with high content of Cu, Zn,...

Purpose: The aim of this article is to identify processes and recognise determinants in the copper mining industry supply chain creation activity taking into account influence CoVID-19 pandemic. Design/Approach: research was conducted using qualitative methods. As part procedure, process analysis carried out method mapping (on example mining). To analyse evaluate examined were presented form gr...
