Designing gold project flowsheets It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore. Mining 1 In lode or vein deposits, the gold is mixed with another mineral, often quartz, in a vein that has filled a split in the surrounding rocks.

Copper processing Copper processing Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.
the ore for aurocyanide in solution, although when no cyanide was present the kinetics of the two processes governed the distribution of gold between the ore and the carbon. Gold was found to reduce at the chalcopyrite surface and a mechanism for this reduction was proposed. For pyrite, a combination of reduction and physical
In refractory ores, pyrite and aresenpyrite often occur in three morphological types: coarse grained, fine grained and blastic or porous. The concentration in each type of sulphide mineral is different and usually varies from ore to ore and so must be determined individually for each deposit and perhaps within each oretype in a deposit. Zoning is a common textural feature of these ores. Often, the gold content of

The principal difference between the highgrade ore A and ore B was the arsenopyrite and pyrite contents. Ore A contained approximately 61 pct arsenopyrite and 9 pct pyrite, and ore B contained 35 pct arsenopyrite and 24 pct pyrite. The lowgrade ore contained only 1 pct arse nopyrite and 5 pct pyrite.
pyrite (Bettles, 2002). Most of gold at Goldstrike is located in arsenian pyrite overgrowths or preore pyrite (Arehart et al., 2003). Naturally occurring organic carbon or TCM is found in many of the ores within the Carlin trend and has the ability to adsorb gold cyanide from the leach solution, a process commonly known as preg

For refractory gold ore processing, pretreatment technologies, such as finegrinding, autoclaving, roasting and biooxidation will also be required. The reason for using different process flowsheet is mainly because gold often occurs in different forms and minerals, and each ore has to be treated differently. Mineralogically, gold is classified as microscopic, submicroscopic gold and surfacebound gold.
