gold plant tailings to regenerate and recovery cyanide for recycling, and presents a technoeconomic argument for the incorporation of this technology into many gold plant flowsheets today. INTRODUCTION. Interest in the recovery of cyanide . from gold and silver plant tailings has heightened in recent years. This interest has been spurred by several
This resulted in a large stockpile of gold tailings which, after test work, are amenable to reprocessing using standard CIL technology. Poseidon has completed a detailed study to evaluate the recovery of the available gold from these tailings using and on site CIL plant and using a local toll treatment smelter to produce the gold.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
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%.

New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources.
Some ores, such as iron ore, are found in relatively high percentages and are fairly easy to separate. Therefore, the resultant tailings are coarser than those from other ores, such as copper, which is found in very low percentages, and requires very fine grinding for separation. Hence, copper tailings are usually quite finegrained.
Jul 19, 2019· The paradigm is shifting, as technology is evolving towards the adoption of smart and hybrid solutions that maximize ore and water recovery while optimizing operational costs.
A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue. The water extracted from the ore by dewatering is recirculated for plant operations after being sent to a water treatment plant.
