Waste electric and electronic equipment, or electronic waste, has been taken into
consideration not only by the government but also by the public due to their hazardous …

Since the birth of cyanidation, it has been dominant in the gold extraction industry. Recently,
with the increasing awareness of environmental hazards and potential risks posed by the …

Many gold producers are today processing gold ores containing significant amount of
cyanide soluble copper. Typically, cyanide destruction is used to prevent the discharge of …

The presence of cyanide soluble copper in the cyanidation of gold-copper ores and
concentrates significantly increases the cyanide consumption in order to achieve sufficient …

In the cyanidation of copper–gold ores, the presence of copper minerals can lead to soluble
gold losses, the production of weak acid dissociable (WAD) cyanide, as well as a number of …

This research proposes a new conceptual process to economically extract platinum group
metals (PGMs), and as a secondary aim, base metals (BMs) from a low-grade concentrate …

The potential effect of ultrasound was investigated, which could lead to cyanide loss or
decomposition during gold leaching. The variations of cyanide concentration during gold …

The geochemical features of the ores present in the oxidation zone of the gold-copper
Malmyzh mineral deposit are characterized. This deposit is located in the the Nanaian …

Numerous studies have been concentrated on the recovery of valuable metals from the
waste printed circuit boards (WPCBs) in recent years. In this review study, metal recovery …

In this study, the applicability of leaching and CIL processes in gold recovery with thiourea
method, alternative to the cyanidation from the refractory Gümüşhane-Kaletaş/Eastern Black …
