Copper tailings refer to the waste generated during the mining and refining process of copper ore, which contains a certain proportion of copper and various other metallic and non-metallic elements,This leads to the formation of large-scale tailings ponds in large-scale mining activities.

In the past,due to technological and cost limitations, copper tailings are widely considered a tricky copper waste. However, with the improvement and development of optoelectronic sorting technology,"copper tailings" have become a huge treasure trove.

一、The harmness of copper tailings

First,the continuous mining activities have led to a huge accumulation of tailings, putting pressure on the environment and land resources.Secondly,the large amount of copper tailings piled up may oxidize into sulfuric acid under specific conditions due to sulfur-containing compounds, leading to acidic water and soil pollution, posing a serious threat to the ecological environment.

Thirdly,there is a safety hazard of "explosion storage capacity" in copper tailings pond.

二、Optoelectronic sorting technology:the savior of copper tailings

The treatment and utilization of copper tailings is an important environmental protection and resource recovery issue all over the world.

As a modern sorting method, photoelectric sorting technology can utilize the differences in optical properties of materials, such as color, texture, associated features, gloss, texture, etc., to finely screen copper tailings, effectively throwing out impurities such as high sulfur iron and enhancing the reuse value of tailings.

So,optoelectronic sorting tech will be the environmental handling way for world tailing pond.
