Introduction Mineral beneficiation is the backbone of modern mining, transforming raw ore into valuable concentrates through a series of meticulously designed processes. After crushing, screening, and grinding to liberate individual minerals, the pivotal stage of separation begins. Among the diverse separation technologies, magnetic separation and electrostatic separation are the two mainstream technologies that utilize differences […]

Recently, at a copper concentrator, I saw fluctuating classification efficiency. When inspecting the cyclone, a worker pointed at the oval-shaped spigot and said, “This should’ve been replaced long ago!” But when exactly? Let’s solve this grinding headache. The spigot diameter should be 5-10% larger than the theoretical calculation, and must be replaced when wear exceeds
