• The grade expected from the pit mining faces (Mine to Mill recon)
• The ROM requirements in terms of grade and inventory
• ROM feed blending requirements for crushing
Run-of-Mine (ROM) feed blending is a crucial process in optimizing the performance of the crushing circuit and ensuring consistent downstream processing. The ROM material, sourced from multiple pit mining faces, often varies in grade, hardness, and moisture content, which can impact crusher efficiency and mill throughput. To maintain a stable feed, blending strategies are implemented to mix ore from different stockpiles, ensuring the desired grade and physical characteristics are met before crushing. This process helps to minimize fluctuations in feed quality, reduce crusher wear, and optimize energy consumption. Proper ROM blending also ensures that the plant operates within its design parameters, preventing bottlenecks and improving overall recovery rates. Coordination between mine planning, stockpile management, and plant operations is essential to achieve the required blend, enhancing both operational efficiency and product quality.
