Application of biosolid on land has been widespread in numerous countries for last several decades. This study performed incubation experiments by mixing a neutral loamy soil and biosolid enriched in Cu, Pb and Zn to explore how heavy metal affects soil mineralization and microbial biomass. The experimental results indicated that large nutrient, microorganism and C sources from biosolid were be...

At present, the use of conventional wastewater processes is becoming increasingly challenging, mainly due to presence biorecalcitrant organic matter. Advanced oxidation such as Fenton, Fenton-like and hybrid have been successfully employed for treatment highly concentrated toxic non-biodegradable pollutants. Here, a series bimetallic catalysts, based on Cu/Fe supported over ZrO2, were investiga...

The Paraíba is an Au-Cu-Mo deposit located in the southern part of Amazon Craton, Alta Floresta Mineral Province, Mato Grosso State, Brazil. It composed Au-Cu-bearing quartz veins and Cu-Mo-rich hydrothermal breccias stockworks, both associated with several alteration zones. integration spectral (reflectance imaging spectroscopy) conventional techniques (core logging, petrography, mineral chemi...

A series of biodegradable Mg-Cu alloys is designed to induce osteogenesis, stimulate angiogenesis, and provide long-lasting antibacterial performance at the same time. The Mg-Cu alloys with precipitated Mg2Cu intermetallic phases exhibit accelerated degradation in the physiological environment due to galvanic corrosion and the alkaline environment combined with Cu release endows the Mg-Cu alloy...

In this study, the natural Cu background concentration and Cu natural and anthropogenic contamination in soil, water and crop were investigated systematically in Huangshi area. The results show that regional geology is the dominant factor controlling the natural Cu background concentration in soil and water, and that pH is important to control the vertical distribution of Cu in soil under the s...

During its 25 years of production from 1972 to 1998, the Gibraltar Cu-Mo mine in east-central British Columbia (Figure 1) milled a total of 324 million tons of ore containing an average 0.351% Cu from four open pits. Fieldwork during 2000 involved just over two weeks of detailed pit mapping at the mine. Results of this work and several earlier intervals of pit mapping conducted in 1998 and 1999...

in order to assess the potential of copper mineralization and its associated elements in soltan meydan basaltic formation situated in the north of shahrud, the method of stream sediment and heavy mineral has been used. to achieve this aim, totally 68 samples of sediments (-80 mesh in particle size) and 6 samples of heavy minerals (-20 mesh in particle size) have been collected in an optimized n...
