China has the largest output of electrolytic manganese metal (EMM), accounting for more
than 98% of the world's total annual production. Meanwhile, it has also caused serious …

Currently, approximately 1.4 billion tons per year of iron ore tailing wastes (IOT) are
generated, mainly in Australia, Brazil, and China. This work describes the characterization …

Amounts of abandoned non-ferrous metal tailings (NMT) piled in the open air are released
under geochemistry and migrated to the surrounding environment, causing severe harm to …

In this study, the metal (loid) fractions in two alkaline iron tailings areas with similar physico-
chemical properties and the enrichment ability of dominant plants in these areas were …

Some metallic tailings from closed mines were scattered in upstream of the Miyun Reservoir,
Beijing, threatening the ecological environment of rivers due to trace metals. The Liuli River …

The exponential growth of electric and hybrid vehicles in the last five years forecasts a waste
problem when their batteries achieve end-of-life. Li-ion batteries for vehicles have been …

In this study, copper slag (CS) was investigated in detail. The leaching mechanisms of the
heavy metals in CS were identified via a pH-dependent leaching test combined with a …

Coal gangue is a resource that is often improperly managed, especially during the current
strategic metal element shortage. Achieving the efficient and green cooperative recovery of …
