Gold production costs at alltime high
At U$1,289, the allin sustaining costs (AISC) for mine production of an ounce of gold in the first nine months of 2022 were at their highest ever, according to the Posted 30 June, 2021 13:00 Costs in the gold mining industry increased for the second consecutive quarter in Q1’21, with the global average Allin Sustaining Cost (AISC) up Rising gold mining costs Q1'21| Gold Focus World Gold Council
Gold miners’ costs reached a record high in 2022 but dropped in
In 2022, average allin sustaining costs (AISC) in the gold mining industry reached a record high, rising by 18% yoy to US$1,276/oz This was 14%, or For instance, a 10% fall in global average ore grade gives rise to a $50/oz rise in average production costs Besides grades and process recoveries, production costs have the Gauging the LongTerm Cost of Gold Mine Production

Processing of refractory gold ores ScienceDirect
Approximate and relative capital and operating costs will be discussed and their major components defined Therefore, it is essential and significative to investigate column biooxidation for this type of gold ore The column biooxidation process of refractory gold ore was characterized by a variety of analytical methods,so they have been designated as Ore A and Ore B Capital and operating cost estimates for different methods of pretreatment were prepared and these estimated costs and ore sulfide grades then used to compare the process economics The Study involved the following activities: • Review existing mineralogy and testwork dataALTA Gold 2012 EDoc Glencore Technology
Minerals & Mining Industry: Bulk Handling and Conveyor Systems
Our systems easily master steep inclines, rivers, and roads Coal, ores, and minerals can be transported on the conveyor belt from the mine to the blending bed in just one hour, even on winding routes up to 25 km long Energyrecovering systems along the way can utilise downhill sections of your route and feed electricity back into the public For refractory gold ores, the processing cost is relatively high because of the expensive pretreatment required to liberate the ultrafine gold particles from sulphide ores; these include pressure oxidation (POX), biooxidation, roasting or ultrafine grindingModelling pyrite oxidation in a refractory gold ore stockpile to

Estimating relative cost of ore refinement/processing :
What I am looking for is to generally gauge the relative cost of processing different ores to obtain an amount of metal such that this much metal is produced (in value): COPPER: $1, SILVER: $2, PLATINUM: $5, PALLADIUM: $8, GOLD: $10 The cost for processing/refining (right now) for this quantity of each metal is estimated as:Gold cyanidation (also known as the cyanide process or the MacArthur–Forrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complexIt is the most commonly used leaching process for gold extraction Cyanidation is also widely used in the extraction of silver, Gold cyanidation
