M515 In Copper Extraction

Mining Case Study

A customer, based in Indonesia, specializes in copper extraction and started using the MDS M515 in their process to extract copper from rocks.

They encountered a recurring issue with residual clay in their stockpiles, leading to unfavorable chemical reactions. Conventional methods fell short in delivering clean rocks for processing.

Location: Indonesia

Machine: M515 Trommel

Application: Copper

The Challenge

The customer required a solution to completely remove clay from raw feed material, ensuring the rocks were pristine for further processing. Additionally, they needed to efficiently stockpile and treat clean rocks with a sulphate solution as part of the heap leaching process.
