Common Ore Deposit Sampling Methods Grooving Method: This method involves digging a groove of a certain size on the ore body, and using all the dug-out ores from the groove as samples. The grooves should be arranged where the mineral composition changes the most. The cross-sections of the grooves are typically rectangular or triangular, with […]
On January 22nd, 2024, we welcomed a customer from South Korea for an on-site visit focusing on our innovative environmentally friendly chemicals for gold extraction. During their visit, our lead engineer, Gavin, conducted live experiments using the customer’s raw materials – electronic components containing high gold content. The results were highly impressive: our eco-friendly chemicals […]
The mixing tank is used to add various reagents such as caustic soda or hydrated lime. These reagents can also be added in the ball mill stage or the agitating tank, and there is no fixed standard; the adjustment is based on the actual conditions of the ore.
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.
