Oct 20, 20140183;32;Liberation Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed i.e. the gold is liberated.
Tank and vat leaching involves placing ore, usually after size reduction and classification, into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution. In tank leaching the ground, classified solids are already mixed with water to form a slurry

I have liked this page a lot, but what i suggest is that, more investigation and lab test have to be done for vat leaching to process even sulphide ore,becaus most area especially in Africa (Tanzania) now days vat leaching is the most way of gold processing,and if there is a new technology for vat leaching to leach sulphide may u send me.

Both methods use a large tank in the column parallel step where gold is dissolved in the slurry (pulp) through a chemical process and combine agitation, oxygen and cyanide. In CIP, the carbon is mixed with a solution of cyanide leach and ore agitated in the Tank leaching, and the adsorption process will separate the gold.
Zambia is located in the inland of central and southern Africa and is rich in natural resources such as gold, silver, copper, cobalt, lead and zinc, iron, manganese, nickel and other metal minerals; phosphorus, graphite, mica, barite and marble and other non metallic minerals; emerald, topaz, sapphire, aquamarine, malachite, garnet and so on
Aug 03, 20160183;32;Applications of this series agitation tank are different from the conventional agitation equipment, which are used for agitating, leaching and carbon absorption in the gold
THE LEACHING AND ADSORPTION BEHAVIOUR OF GOLD ORES Kevin Lee Rees from the dissociation of the complex is used to leach gold from the ore. The stepwise This batch model was extended to a continuous model that simulated three leaching and seven carbon in leach tanks. The effect of processing the oxide and sulphide ores
Procedure . The ore or concentrate is fed as slurry or pulp into the leaching tank where it is mixed with a lixiviant, usually an aqueous solution, which acts as a solvent.The duration of the leaching operation can range from hours up to 5 days, the latter retention time being normal when refractory gold

Spent Ore from Tank Leaching (Tailings)Tank leaching, both CIP and CIL circuits, generate spent ore by leaching the gold values from finely ground ore. The spent ore exits the leach circuit as a slurry composed of gangue and process water bearing cyanide and cyanide metal complexes. The tailings
Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carbon in pulp circuit (CIP). The reagent and utilities operating costs associated with leaching, adsorption, elution and
lurgical gold extraction routes utilize a leaching step to produce a gold bearing solution as an intermediate product while the recycling of secondary gold from electronic and precious metal scrap is based on the selective and fast dissolu tion of the precious metal. Therefore, A Method for Leaching or Dissolving Gold from Ores or Precious
Apr 25, 20180183;32;Heap leaching can take anything from a couple of months to several years. In the case of gold recovery, heap leaching generally requires 60 to 90 days to leach the ore, compared to the 24 hours required by a conventional agitated leach process. Gold recovery is also usually only 70% compared with 90% recovery in an agitated leach plant.
Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes
Gold Leaching( carbon in leach) process is widely used in the newly built gold leaching plants in recent years, and a lot of plants are changing into CIL as well.Gold Leaching CIL process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high grade silver.
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.
