🔍 Copper-Molybdenum Ores: How to Crack the "Low-Grade, Fine-Grained, and Complex" Challenge?

⚙️ "Low-grade" refers to the generally low metal content of the ore; "fine-grained" indicates that the copper and molybdenum minerals are disseminated in extremely fine particles, often ranging from 0.02 to 0.25 mm; and "complex" refers to the intricate mineral composition, where chalcopyrite and molybdenite are closely associated and share similar floatability, making separation exceptionally difficult.

📌 Even more challenging is the presence of significant amounts of gangue minerals—such as feldspar and dolomite—that are prone to sliming. During the grinding process, these minerals easily generate large quantities of slime. This slime coats the surface of valuable minerals and degrades the flotation environment, leading to high reagent consumption, unstable flotation performance, and operational difficulties. Efficiently recovering copper and molybdenum from complex ore bodies characterized by high slime content and fine particle sizes has long been a core technical challenge in mineral processing.

Frothers play a crucial role in the copper-molybdenum flotation process; they disperse air into the pulp as stable, fine bubbles, providing a carrier for valuable minerals to float to the surface.

🥳 Y&X’s Flometal Q62 frother offers strong foaming capabilities. Its bubble diameter, coalescence rate, and froth layer thickness have been meticulously optimized to effectively enhance concentrate grade and recovery rates. It successfully boosts molybdenum recovery by over 3% and molybdenum concentrate grade by more than 2%, serving as an effective replacement for MIBC.

In copper-molybdenum flotation, the frother is by no means a minor player; it is a core variable that determines froth layer quality, mineral transport efficiency, and separation selectivity.
