Polyacrylamide for Mineral Processing And Metal Smelting Wastewater Treatment in Southern Europe

The manufacture of non-metallic minerals and construction materials (cement, bricks) emit 15% of PM10 and PM2.5 (CITEPA, 2010). The industries are responsible for the issuance of a vast majority of heavy metals.

At high concentrations many metals are toxic, as also are those metals which are essential for mineral nutrition such as Cu, Zn and Fe (Marmiroli and Maestri 2008). The most interesting feature of metal ions is the high affinity for S, N and O atoms in organic molecules: binding to proteins and nucleic acids can determine toxic effects in ...

6.1. Bismuth production. Although Bi has been the main economic product from some mines, such as Tasna in Bolivia, most Bi is a by-product of Pb and W extraction and processing. Annual global production in 2020 was 3700 tonnes, falling from a ten year high of 6300 tonnes in 2019 ( Brown et al., 2021) ( Fig. 7 ).

University wastewater is a type of wastewater with higher pollutants load and flow rate variability than typical domestic wastewater. Constructed wetlands (CW) could be used for university wastewater treatment and consequently for wastewater reuse. A hybrid CW pilot plant, at the University of Bologna (Italy), was monitored to assess its potential to be used at the university.

Jul 01, 2020 · Mining and related activities (e.g., metal processing and smelting) discharge large amounts of waste water, flue gas, and solid waste to the environment, which often contain arsenic (Yang et al., 2013). Thus, arsenic enters into soils through atmospheric deposition, surface runoff flushing, or weathering (Smith et al., 1998).

The potential of households’ used cooking oil (UCO) recycling for biodiesel production is massive. This study aims to promote the shift from UCO inappropriate disposal to sustainable recycling.
