Outotec's cyanide leaching plants are available as gold adsorption directly from the process slurry in carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solid-liquid separation by Merrill-Crowe and carbon-in-column operations.
The ores are unique, with the gold occurring as sub-micron particles in a porous host rock. The preliminary test work on representative samples from the region shows that a satisfactory recovery of the gold can be obtained by heap leaching the ores with cyanide at a relatively coarse size.

A key factor in the profitability of small mining operations is the advent of an alternative to conventional mining and milling operations—solution mining (leaching). Basically gold and silver leaching involves spraying a cyanide solution on the ore to dissolve the metal values, collecting the solution containing the dissolved metals, and ...
Non-cyanide gold leaching agent (also can be called Non-cyanide gold dressing agent or Non-cyanide gold dissolving agent) is mainly applicable to heap leaching, tank leaching, and carbon paste (agitation leaching) processes of fine grind gold and silver ore.

Heap Leaching of Gold and Silver Ores ScienceDirect. Mining of ore for heap leaching employs the same techniques and equipment as mining of ore to feed any other process method. Where uncrushed ore (runofmine (ROM) ore) is placed on the leach pad, ore may be blasted very heavily in order to reduce rock size and improve gold recovery.
Jul 10, 2017· Ammoniacal thiosulfate leaching of refractory oxide gold ore was investigated. According to X-ray fluorescence and fire assay analyses, the ore contained about 33.01 wt% Si, 8.53 wt% Al, 7.26 wt% K, 3.00 wt% Fe, and 2.80 ppm Au.
Double refractory gold ores, such as Barrick's Goldstrike ore, contain both pyrite and carbonaceous matter and the latter results in the loss of gold from solution during cyanide leaching.

Leaching . Leaching is accomplished by agitating fine solid material with a liquid solvent in contact with a gaseous reagent such as air (for the leaching of gold and uranium ores and sulfide concentrates), percolating the liquid reagent through a motionless layer of the solid (the leaching of copper from oxidized ores and of aluminates from caked bauxites).
New Chloride Leaching Process for Gold Extraction from Refractory Ores WS Rapson REFERENCES attainment of higher leaching temperatures and higher efficiencies possible. Decomposition ofthe refractory sulfides and arsenides occurs in the chloride leach solutions and their gold content made susceptible to cyanide leaching.
new generation of leach products for gold hard rock ores without cyanide or mecury, to replace toxic methods with environmentally safe leach gold with non-cyanide products, small and medium scale gold miners leaching hard rock ores. alternative to amalgamation
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%.
Bacterial extraction of gold from sulfide bearing ores has been studied by many investigators. If gold occurs finely disseminated within the sulfide ore matrix such as in pyrite, arsenopyrite and pyrrhotite, the leachant can not penetrate into the inside of solid ore in order to leach the enclosed submicron size gold particles. For their liberation, the sulfide bearing ore is subjected to ...

1. Introduction. Cyanidation is the method applied for recovery of gold from ores for a century. New cyanidation processes based on the recovery by adsorption to activated carbon of leach solutions containing low-grade (concentration) gold have been developed since 1970s and 85% of gold recovery is accomplished with this technique today (Gönen, 1992, Hendrix, 1994, Örgül and Atalay, 2002).
