In heap leaching, do we need to treat the activated carbon? If the customer’s conditions do not allow for processing the activated carbon, will it affect the leaching effect?

January 10, 2024 in /by

For heap leaching, simple washing of the activated carbon is sufficient for use, or adding a small amount of activating agent during the adsorption process is enough. It’s a simple process that doesn’t require special treatment, or you can simply provide the customer with high-quality water-washed carbon.

How to distinguish good activated carbon from bad activated carbon? Is the iodine value really the only criterion? Why is it said that some activated carbon with an iodine value of over 1000 is still not good? What is the reason for this?

January 10, 2024 in /by

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 […]

 Is iron a significant factor in the cyanidation process?

January 10, 2024 in /by

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.

what silver content does it become worthwhile to make a separate selection? What temperature is required during smelting?

January 10, 2024 in /by

For separate silver processing, a concentration of 50 grams per ton or higher warrants the use of zinc wire or zinc powder for replacement. During smelting, a temperature of at least 1300 degrees Celsius is required. Both gold-containing and silver-containing materials can be melted at this temperature. It’s important to note that this temperature refers […]

What sulfur content is considered high sulfur?

January 10, 2024 in /by

There is no strict standard for sulfur content that represents its impact on the leaching rate. Generally, 4%-5% or higher sulfur content is considered relatively high, indicating a preference for flotation. However, many high-sulfur minerals still exhibit good leaching rates, so there isn’t a strict distinction criterion; judgment is typically based on individual experimental results.
