Our combined beneficiation process for magnetite ore consists of several key steps. First, the raw ore undergoes crushing and grinding pretreatment to achieve sufficient mineral liberation. Then, it enters the deep reduction stage, where the ore powder is mixed with a reductant and flux and reacted at high temperature to convert iron oxides into metallic iron. Subsequently, the product is quenched, crushed, and separated through stage grinding and magnetic separation. The obtained concentrate is then classified by particle size, producing different grades of products to meet the needs of casting, powder metallurgy, steelmaking, etc. Finally, the tailings are properly treated.
Fluorite ore can be classified into different types based on the characteristics of the gangue minerals, including quartz-type, sulphide-type, barite-type, and carbonate-type. Different types of fluorite ore require distinct mineral processing techniques.
Molybdenum (Mo) is a critical metal used in steel alloys, lubricants, and catalysts. Extracting it efficiently relies heavily on the flotation process, the primary beneficiation method for separating molybdenite (the main Mo-bearing mineral) from the ore.
With the depletion of easily recoverable tungsten resources, the flotation of fine-grained scheelite has become a critical challenge for efficient tungsten utilization. These ores are characterized by fine dissemination, high surface energy, and surface property convergence with calcium-containing gangue minerals (e.g., calcite), leading to inefficiencies in conventional flotation.
This article provides an in-depth analysis of key scheelite beneficiation equipment and technologies, including centrifugal flotation machines, microbubble columns, and magnetic-flotation hybrid systems. Focused on fine-particle recovery and eco-friendly designs, it explores cutting-edge trends like intelligent control and multi-force field separation, offering solutions to enhance efficiency and sustainability in processing low-grade, complex scheelite resources.
Scheelite, a critical strategic resource in China, requires optimized beneficiation processes due to its fine dissemination and complex association with gangue minerals (e.g., calcite, fluorite). Current mainstream processes focus on roughing and cleaning stages, evolving toward higher efficiency and precision.
Magnetic separation is a core process in iron ore beneficiation, with diverse equipment types tailored to different magnetic minerals and particle sizes. Based on global technological advancements, this article systematically introduces key magnetic separators and their applications.
China's fluorite resources are predominantly low-grade and associated with calcite (CaCO₃), which are finely disseminated and complexly intergrown, making conventional physical separation inefficient. Flotation, the core technique for fine-grained minerals, faces significant challenges in separating fluorite from calcite
The associated silver minerals of silver-manganese ore mainly exist in the form of natural silver, gold-silver ore, silver-gold ore, etc., in the form of fine particles, and are isomorphously present in the manganese ore lattice. It is difficult to obtain high-grade silver concentrate by mechanical separation, and it is also difficult to obtain good silver leaching indicators by a single cyanidation method. It is recognized as one of the difficult-to-treat silver-containing ores.
Lithium, a core material in the new energy sector, faces surging demand driven by electric vehicles and energy storage. In China, lepidolite (chemical formula: KLi₂Al₄Si₅O₁₀F₂OH) has emerged as a critical lithium source due to its abundant reserves, despite challenges like low grade and complex composition.
