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.

  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 height of the ore heap in heap leaching should be determined based on the characteristics of the ore, which can vary significantly. The slope should be managed accordingly. It is preferable to choose a flat terrain for the heap.

The standard for judging the quality of activated carbon is based on two factors. Firstly, the higher the iodine value, the better the adsorption capacity, and the more fragile the activated carbon, making it unsuitable for carbon slurry. Secondly, the amount of residue after the activation carbon which is burned should be minimal. The residue can […]

In ore processing, iron is not harmful or influential. Co-occurrence of iron and gold is quite common, and the specific recovery rate depends on the different types of ore. There are cases where iron content is high in gold-bearing iron oxide ore, yet the recovery rate is very good.
