Antimony (Sb) is an impurity element that is increasingly encountered in the mineral
processing/metallurgical industries of gold, copper and lead. Its occurrence in metallurgical …

Abstract Enargite (Cu 3 AsS 4) and arsenopyrite (FeAsS) are the most abundant arsenic
containing sulfide minerals in the world. The existence of arsenic can significantly …

Antimony is classified as a critical/strategic metal. Its primary production is predominated by
China via pyrometallurgical routes such as volatilization roasting—reduction smelting or …

This work investigated the selective removal of arsenic from a lead‑antimony‑zinc-containing
high arsenic dust in alkaline solution. The effects of sodium hydroxide (NaOH) …

The supply of metals is increasingly challenged by high demand for raw materials and the
depletion of high-grade ore deposits. In addition, the management of tailings from metal …

The alkaline leaching of arsenic (As 2 O 3) by Na 2 S, together with its precipitation by Fe 2
(SO 4) 3 was studied. Response surface methodology based on central composite design …

World copper (Cu) production has been strongly affected by arsenic (As) content, because
As-rich Cu concentrates are not desirable in the metal foundries. When As-rich Cu …

Pollution resulting from hazardous glass (HG) is widespread across the globe, both in terms
of quantity and associated health risks. In waste cathode ray tube (CRT) and fluorescent …

Leaching of enargite samples containing approximately 12% As, 0.5% Sb and 39% Cu was
studied in alkaline sulphide solutions containing sodium hydroxide and sodium sulphide …

The selective removal of arsenic from arsenic-bearing dust containing Pb and Sb in alkaline
solution was studied. The influence of NaOH concentration, temperature, leaching time …
