Metal-bearing solid wastes are an important secondary source of metals. Compared to
mining from ores, the recovery of metals, especially precious metals from rich secondary …

Lead slag is produced by the primary and secondary lead industry. The large amount of lead
slag discharge causes environmental problems. Reducing the toxicity and increasing …

Mining has advanced primarily through the use of two strategies: pyrometallurgy and
hydrometallurgy. Both have been used successfully to extract valuable metals from ore …

Abstract Platinum Group Metals (PGMs), often with associated gold, have very few
occurrences where they are present in an ore deposit at economically extractable levels …

It is well known that the leaching of chalcopyrite has very slow kinetics. The generally higher
reactivity of chalcopyrite in chloride as opposed to sulfate solutions has resulted in many …

The leachability tests for manufacturing scrap TV boards (STVB) have indicated the release
of metals beyond the limit levels with potential problems for environmental pollution …

A study was conducted for metal recovery from low-grade copper sulfide tailings using the
leaching and fractional precipitation methodology. Mineralogical characterization of the …

It is well known that the Chilean mining industry is facing a shortage of water resources for
the sustainable operation not only of existing plants but also of future projects. In addition …

Leaching studies of chalcopyrite (CuFeS 2) notoriously reach divergent conclusions about
kinetics, mechanism, and passivation behavior during leaching, even for the same lixiviant …

This work investigates the effect of an agglomeration and curing pretreatment on leaching of
a copper sulfide ore, mainly chalcopyrite, using mini-columns in acid-nitrate-chloride media …
