Apr 11 2018 · Gold Leaching carbon in leach was developed from CIP Carbon In Pulp is characterized by less process flow timesaver in the leaching process thus reducing the production expenditure Besides advanced extraction technology improving the efficiency of gold extraction The CIL production line is wider use than CIP in the mineral industry
The CIL process The carboninleach CIL process illustrated in Figure 3 is a variation of the CIP process In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously Capital cost is reduced as
3 CarbonInLeach CIL The carboninleach process integrates leaching and carboninpulp into a single unit process operation Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution The CIL process is frequently used when native carbon is present
Carbon Adsorption In Recovery Of Gold From Cyanide Leach Solutions It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years and many papers have been written on the subject Carbon as a media of recovery for gold from leach solutions did not gain wide acceptance in the gold industry until the 1970s with the explosion of heap leaching of vast quantities
Processes Gekko Systems are leaders in the development of energyefficient preconcentration flowsheets that deliver stepchange benefits Focussing on the gold industry Gekko replace highenergy whole ore treatment of gold by carboninleach CIL methodologies with
Cyanidation carbon adsorption process is the most widely used in gold cyanide extraction process The principle in brief is the carbon could adsorb liquid gold from cyanide solution In 1970s with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold make recycle the carbon and reduce the cost and easy to process the gold ore with
CarboninPulp CIP and CarboninLeach CIL processes have surface areas of about 1000 m²g ie one gram of activated carbon the amount of which will occupy the same space as the end of a persons thumb has the same surface area as two football fields
Metallurgy Metallurgy Leaching Oxides are leached with a sulfuric acid or sodium carbonate solvent while sulfates can be leached with water or sulfuric acid Ammonium hydroxide is used for native ores carbonates and sulfides and sodium hydroxide is used for oxides Cyanide solutions are a solvent for the precious metals while a sodium chloride solution dissolves some chlorides
3 CarbonInLeach CIL The carboninleach process integrates leaching and carboninpulp into a single unit process operation Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution
Focussing on the gold industry Gekko replace highenergy whole ore treatment of gold by carboninleach CIL methodologies with beneficial lowenergy process solutions Harnessing both gravity separation and floatation as well as dramatically reducing the initial mass to be processed by preconcentration Gekko flowsheets increase the grade
Occasionally carbon columns will be used with tank leaching operations also especially if the mine has a dual leach system heap leach of low grade and tank leach of high grade Carbon columns consist of large columns 5 to 8 ft diameter and 15 to 20 feet in height charged with activated carbon
the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank This paper presents a dynamic model that describes with minor changes the carboninleach the carboninpulp and the gold leaching
PregRobbing Minerals Typically pregrobbing carbon is managed in one of five ways Carbon in Leach CIL – Adding activated carbon with a much higher adsorptive capacity than natural carbonaceous material during the leaching process
tonne of carbon is achieved leaving as little as 001g of gold per tonne of solution in the tailings There are essentially three process varieties that use carbon adsorption The carbon in pulp CIP process The carbon in leach CIL process and The carbon in column CIC process
This batch model was extended to a continuous model that simulated three leaching and seven carboninleach tanks The effect of processing the oxide and sulphide ores studied was examined and the model shown to satisfactorily describe the extraction of gold from the Telfer oxide ore A sensitivity analysis of the effect of process changes
