During the carbon slurry process, the additives caustic soda or hydrated lime can be added at the stage of ore entering the ball mill; the dosage is determined based on the ore consumption and is not fixed.
The recommendation for a rectangular heap is to improve water permeability. To determine whether all the ore has been fully permeated, small barriers can be created on the surface of the heap, similar to paddy fields, and the water level in each barrier can be observed to assess the quality of permeation. In the initial […]
To determine whether a certain type of ore is suitable for cyanidation or flotation and reselection, visual assessment is followed by various targeted experiments to obtain various data, ultimately determining the optimal processing method through comprehensive evaluation.
The entire process of cyanide leaching for gold extraction is as follows: The cyanide process involves using a reagent to react with the ore, dissolving the gold from the ore into the reagent solution. The gold is then adsorbed and replaced, initially concentrated, and then refined through smelting to obtain the final product of gold […]
The methods for cyanide gold extraction are pit leaching, heap leaching, and carbon slurry adsorption (CIP or CIL), which allow thorough mixing of reagents and ore.
The “cyanide” in cyanide gold extraction refers to the cyanide ion content.
No, it is not possible. Large gold particles cannot be dissolved by the reagents. It is necessary to first use gravity separation to recover the free gold particles before cyanidation.
The fineness of the ore is closely related to the recovery rate. The optimal fineness varies for pool leaching, flotation, and carbon slurry. The degree of oxidation and the size of the gold also determine the fineness variation. In conclusion, different ores have different optimal processing methods.
Activated carbon adsorption cannot be determined by time; it can only be judged based on assay results. There is no specific time standard for this process.
The minimum requirements for carbon slurry cyanidation are grade and recovery rate. It is crucial to conduct experiments to determine the optimal processing method for the ore.
