Vancouver British Columbia Ero Copper Corp. (the "Company") (TSX ERO) is pleased to announce the results from its comprehensive ore sorting trial campaign which commenced in the first quarter of 2020 and tested approximately 29 000 tonnes of material through early September. Material from eight sources within the Curaçá Valley were tested representing a range of grade profiles.
Nov 17 2022The verification efficiency and precision of copper ore grade has a great influence on copper ore mining. At present the common method for the exploration of reserves often uses chemical analysis and identification which have high costs long cycles and pollution risks but cannot realize the in situ determination of the copper grade. The existing scalar spectrometric techniques generally

ore sorting to have most value material should not be blended prior to the ore sorting point. This means that high grade copper has an equal probability of being located anywhere on the belt. If only the center and/or the surface of the material is measured accurately there is a high likelihood that high or lowgrade material will be missed.
Copper processing is a complicated process that begins with mining of the ore (less than 1 copper) and ends with sheets of pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
The extracted ore has a relatively low average copper grade of around . This results in relatively high processing costs and creates the need to search for solutions to reduce the costs for ore processing at Los Bronces. Sorting by sensor technology may be a solution to decrease these processing costs.
