Cyanidation of a copper-gold ore ScienceDirect

Abstract. A free milling gold ore, which contains 0.4% copper as chalcopyrite, was treated with cyanide. In the pre-leaching, the kinetics of oxidation of soluble sulphides are not an accurate indication for the length of the treatment. Efficient gold leaching is achieved only under specific conditions using oxygen, lead nitrate and a high

Cyanidation of a copper-gold ore ScienceDirect

1997-8-1  The addition of lead nitrate and oxygen is a common practice during the cyanidation of sulphide bearing gold ores (Desch~nes and Putz, 1995). From the lack of specific information in the literature and diversity of practices in gold plants, it became apparent that a systematic assessment of the addition of lead nitrate and oxygen is required.

(PDF) Cyanidation of Refractory Gold Ores: A Review

The insusceptibility of gold ores to conventional cyanidation is defined by its mineralogical information and exacerbated by the continuous decline in gold grade. The depletion of

How gold is extracted by Cyanidation Process

2020-6-17  Cyanidation is a method used in the extraction of gold from its ore. This extraction is done by converting the gold to a water-soluble form. The cyanidation process of gold extraction or the use of cyanide is the most common leaching process, used in the extraction of gold from its ores. Some countries do not approve of this method of gold

Cyanidation of a pyrrhotite-bearing gold ore

2015-12-27  The presence of pyrrhotite in gold ores is known to have a negative impact on the dissolution of goldand on the consumption of cyanide. This report presents the results of a cyanidation study on a samplecontaining pyrrhotite as the only cyanicide. The purpose of the study was to evaluate the detrimental effectof pyrrhotite as a cyanicide and to determine the best cyanidation conditions to

Gold Cyanidation Process 911 Metallurgist

2016-6-8  The gold cyanidation process is the most important method ever developed for extracting gold from its ores. The reasons the widespread acceptance of cyanidation are economic as well as metallurgical. It usually obtains a higher recovery of gold than

(PDF) Cyanidation of a pyrrhotite-bearing gold ore

The Musselwhite Mine in Canada processes a free milling gold ore at 5.5-5.8g/t Au and 4.2% pyrrhotite. A laboratory investigation was conducted to improve cyanidation. The pyrrhotite

Improvements in gold ore cyanidation by pre

2017-7-1  It is known that the presence of sulphidic minerals in the cyanidation of gold ores may cause significant consumption of oxygen supplied in the injected air. This may result in dissolved oxygen starvation for the oxidative leaching of the gold, and ultimately it will reduce the maximum attainable recovery of gold from the ore.

Gold-Copper Ores ScienceDirect

2016-1-1  A large portion of the research and development into approaches to economically treat via cyanidation gold ores with high soluble copper has focused on the recovery and recycle of cyanide (Figure 43.8). Many of these processes utilize the change in copper cyanide speciation and stability with pH and competing copper complexing agents (e.g., ammonia and sulfide) to recover the cyanide.

Advances in the Cyanidation of Gold ScienceDirect

2016-1-1  Abstract. Cyanidation, a process used for over a century to extract gold from free milling ores, is so effective that it can economically treat low-grade ores (0.5 g/t Au). The concentration of cyanide added to dissolve gold is much higher than the stoichiometric requirement because of
