Mining will involve extensions of the current oxide only open pit mining areas to extract the deeper gold sulphide refractory ore zones. Sulphide ore is then hauled to the existing run of mine (ROM) and stockpile areas for treatment. Snowden (Dec 2016) mentioned the load and haul fleet was selected to achieve close to 8,000– 10,000 t/d movement.

Guides For High-sulfide Gold Processing - cnlitereagent

2020-3-17  High sulfide gold ore refers to 20% -30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotation-cyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly used gold processing methods for high-sulfide gold

What is Sulfide Mining? Mining Action Group

What is Sulfide Mining? Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to ...

Recovery of gold from sulfide refractory gold ore ...

2021-4-1  Typically, gold is encapsulated or finely disseminated in refractory gold ores and the direct cyanidation is not effective for gold extraction from these ores, even after the ore is ground to exceeding small particles (Nazari, 2017, Corrans and Angove, 1991).Especially for sulfide refractory gold ores, in order to recover gold, many oxidation pretreatment technologies were proposed including ...

2021-9-30  They said it had a lot of silver and copper, but no gold. A geologist said that the fire assay may not have extracted the gold from the ore, because of the various gold-silver-copper sulfur refractory compounds within due to a limited process that was used. This type of ore requires more extensive process steps to reduce the gold.
