This paper aims to summarize these studies and present a systematic review of the mineral processing of gold ores, with a particular focus on alternative leaching reagents to cyanide that can facilitate cleaner extraction.
The quantity found in solution will furnish an estimate of how much lime will be needed for making up the cyanide extraction test. Generally, a residual strength of 0.05% CaO will indicate a suitable quantity of lime for an all-gold ore, and 0.1% for a silver or silver-gold ore.
The global decrease in ore mineral grades and increase in ore mineralogical complexity has triggered the modern mining industry and research communities to search for efficient methods of processing ores which were initially considered uneconomic [ 1, 2 ]. Gold-bearing copper minerals are common occurrences in many gold deposits and …
The hard rock gold mining process enables the extraction of valuable gold from rocks and ores, mainly including crushing, grinding and gravity separation to form gold processing plants. The plant is large processing capacity, low operating cost, and can recover even fine gold particles efficiently.
Thiosulphate leaching is a process that removes gold from gold bearing ores without the use of cyanide. Although not as aggressive a leaching agent as cyanide, thiosulphate offers several technological advantages including its lower toxicity and greater efficiency with gold deposits associated with preg-robbing ores. The thiosulphate leaching process, followed …
The effect of pH value on gold extraction for various ore types is shown in Figure 28.4. Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH 9.5–10.0, whereas for some carbonaceous ores, pH value has no apparent effect. However, the outcome will vary depending on the nature of the …

After the ore is mined, the rock can be crushed and heap leached or ground and leached depending on the ore grade and chemistry. For heap leaching, crushed ore may be placed in heap leach facilities (HLFs), where the ore is irrigated with process solutions for the recovery of precious metals. The processing of ground ores generates …
The engineers and metallurgists that built many of those initial plants used a similar recipe for the flowsheet design and they worked well, but there was room for improvement. The improvement is not necessarily an increase in gold recovery as much as an efficient increase in the volume of ore processed along with a significant reduction in costs. The …
