Neves Corvo is an underground high-grade Cu–(Sn)–Zn mine, located in the Portuguese part of world-class Iberian Pyrite Belt (IPB), which currently producing copper, zinc, and lead concentrates. The operation owned by SOMINCOR, a subsidiary Lundin Mining, with maximum capacity 2.6 Mtpy for copper processing plant 1.0 zinc plant. From 2010 till end 2019, mine has accumulated 7.3 Mt waste rock 17 ...

To reduce the workload and misjudgment of manually discriminating microseismic events blasts in mines, an artificial intelligence model called PSO-ELM, based on extreme learning machine (ELM) optimized by particle swarm optimization (PSO) algorithm, was applied this study. Firstly, difference between mine previous research results, 22 seismic parameters were selected as discrimination feature t...

nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (anfo) explosive at the sungun surface mine, located in the northwest of iran. the pollutants were monitored during some blasting operations at the mine. it was concluded that the gases and dust clouds initially went up to the ...

This report addresses the challenges encountered and, to a certain extent, overcome, while health risk assessment and management were being conducted in Mae Sot, Thailand following cadmium contamination to rice, the main diet of Thais. In November 2003, Department of Agriculture (DOA), Ministry of Agriculture (MOA) sent a summary report of a 6-year study revealing serious contamination of cadmi...

The soil heavy metal pollution around the mine threatens crop growth and human health. Intensively studies of distribution characteristics source metals some typical mines are very crucial for environmental management green development mine. A total eighty-nine samples, twenty-one sediment five waste rock samples two tailing sand were sampled to investigate copper (Cu), lead (Pb), zinc (Zn), ar...

The spatial patterns, ecological risks, and sources of heavy metals (HMs), including Pb, Zn, Mn, Cu, Cd, Hg, As in river sediments, were identified around a lead-zinc mine Danzhai, Guizhou, China. concentrations selected HMs their coefficient variations indicated that the sediments this typical obviously contaminated with HMs. Anthropogenic activities had further enhanced accumulation higher co...

slope stability is one of the major and determiner parameters in the economy and safety of open pit mines. failure and consequently rupture of the slope caused no compensable economic and humanity losses. so, probability assessment of the further failure for presentation of damages and additional costs is of prime importance. in this research, stability analysis and probability assessment of th...

Mine tailing storage represents an important environmental issue. The generation and dispersal of dust from mine tailings can contaminate air surrounding soils. In addition, metals soluble salts present in these wastes could pollute groundwater surface water. recovery contribute to minimize the risk achieve a circular economy model. main objective work is study use two carbon-based materials, c...

This study was designed to investigate heavy metal (Cu, Zn, Pb, and Cd) contamination levels of soils, vegetables, and rice grown in the vicinity of the Dabaoshan mine, south China. The concentration of Cu, Zn, Pb, and Cd in paddy soil exceeded the maximum allowable concentrations for Chinese agricultural soil. The heavy metal concentrations (mg kg(-1), dry weight basis) in vegetables ranged fr...
