Primary metal production operates with large tonnages and takes advantage of economies scale. Metal recycled from low-value waste streams, competing in the same global market as primary production, will be more competitive by also taking up-scaling. However, an overview streams to see upscaling potential needs provided literature. In response, this study provides estimates copper, zinc, lead in...

Water quality affects the flotation recovery of minerals and their separation. Mining-process waters become saturated with soluble salts after contact (oxidation dissolution) during crushing, classification flotation. Inorganic species, such as metal ions but also carbonate sulphate ions, may have a positive or negative effect on mineral As are always found in high concentrations process waters...

The impact of agriculture, forestry and metal mining on the quality of fine-grained sediment (<63 μm) was investigated in the Quesnel River Basin (QRB) (~11,500 km(2)) in British Columbia, Canada. Samples of fine-grained sediment were collected monthly during the snow-free season in 2008 using time-integrated samplers at replicate sites representative of agriculture, forestry and mining activit...

All steps of a mining project generally disturb the environment'soriginal condition during construction. Therefore, it is crucial toimplement an appropriate mine reclamation plan throughout all mineplanning stages from sustainable and environmental point of view.Planting the suitable plant species in each step of any reclamationplan and each area is one of the necessities in this respect.Select...

Truck-Shovel fleet, as the most common transportation system in open-pit mines, has a significant part of mining costs, for which optimal management can lead to substantial cost reductions. Among the available dispatch mathematical models, the multi-stage approach is well suited for allocating trucks to respected shovels in a dynamic dispatching program. However, with this kind of modeling sequ...

The life cycle cost of a system is influenced by its maintainability. Maintainability is a design parameter, whose operational conditions can affect it significantly. Hence, the effects of these operational conditions should be quantified early in the design phase. The proportional repair model (PRM), which is developed based on the proportional hazard model (PHM), can be used to analyze mainta...

Soils around mining sites play a significant role in the transport and control of heavy metals in the environment. Therefore, understanding the adsorption properties of soil is essential in solving pollution problems. The objective of this paper was to study Zn(II) adsorption onto Sarcheshmeh copper mine soils. The adsorption isotherms of Zn(II) were studied. The Langmuir isotherm indicated an ...

Abstract Mining activities have significantly affected the Neotropical freshwater ichthyofauna, most diverse in world. However, no study has systematized knowledge on subject. In this review, we assembled information main impacts of mining crude oil, gold, iron, copper, and bauxite aquatic ecosystems, emphasizing fishes. The obtained shows that generate several different disturbances, mainly vi...

Mining exploitation leads to slow or rapid ground subsidence resulting from deformation until the collapse of underground post-mining voids following excavation activities. Satellite SAR interferometry capabilities for evaluation movements allows monitoring intensive surface mine and can provide new knowledge about risks in mining industry. This work integrates both conventional advanced Differ...

This work proposes an environmentally safe and economically feasible method of waste copper-nickel production slag utilization (Kola Mining-Metallurgical Company, Nornickel, Kola Peninsula, Russia). process involves the decomposition by diluted solutions sulfuric acid (7–10 wt.% H2SO4) with a transfer in solution more than 70% silicon, 77% iron 78% magnesium, concentration non-ferrous metals re...
