It is very necessary to conduct photoelectric sorting of gold ore before tank leaching. The main reasons are as follows:

1. Improve the recovery rate of gold

Photoelectric sorting technology can separate the concentrate and waste rock in the gold ore by identifying the differences in comprehensive characteristics of the gold ore surface, such as texture, color, gloss, shape, and reflectivity. This can enrich the gold ore before tank leaching and improve the recovery rate of gold, especially for low-grade gold ore.

2. Reduce processing costs

Through photoelectric sorting, the original ore can be pre-discarded before tank leaching to reduce the processing level of the original ore, thereby saving the processing cost of subsequent processes. For example, when the gold ore after pre-discarding is subjected to flotation or chemical separation, the amount of ore processed can be reduced, and the consumption of reagents and energy can be reduced.

3. Improve tank leaching efficiency

The gold ore after photoelectric sorting has a higher grade and fewer impurities, which helps to improve the leaching rate of gold during tank leaching. At the same time, since photoelectric sorting can remove some impurities that have a negative impact on the tank leaching process, the tank leaching process parameters can be optimized and the tank leaching efficiency can be improved.

4. Environmentally friendly

Photoelectric sorting produces almost no pollutants such as wastewater and waste residue during the process, which is a more environmentally friendly way of mineral processing. This is of great significance for protecting the natural environment and meeting the requirements of sustainable development.

It is necessary to carry out photoelectric sorting before tank leaching of gold mines. It can improve the recovery rate of gold, reduce processing costs, improve tank leaching efficiency, and has the advantages of environmental friendliness. With the continuous advancement of technology, the application of photoelectric sorting technology in gold mine processing will become more and more extensive.

Photoelectric sorting equipment is easy to install, has low requirements install site, and has low energy consumption (the main energy consumption is electricity). The host is enclosed, dust-proof, high temperature resistant, and corrosion-resistant, and is suitable for the working environment of the industrial and mining industry.
