Is Your Tungsten Ore Processing Method Maximizing Recovery and Profit?

Tungsten, a versatile and widely distributed element, is a crucial component in various industries, from manufacturing to technology. Despite its common presence in rocks, economically viable deposits are rare, making efficient extraction and beneficiation essential for maximizing yield. As the world’s leading producer, with significant reserves concentrated in the Nanling Mountains of Southern China, China plays a pivotal role in the global tungsten market. This article explores advanced tungsten ore beneficiation methods, focusing on wolframite and scheelite separation techniques to help global miners optimize their operations.

The Challenge of Tungsten Ore Processing
From raw tungsten ore to a marketable product, several critical steps are required. The primary beneficiation methods for tungsten ore include manual separation, heavy medium separation, gravity separation, flotation, magnetic separation, and electric separation. The choice of method largely depends on the type of tungsten ore:

1.Wolframite Tungsten Ore:
Gravity Separation: Due to its high density, wolframite is best processed using gravity separation. This method is cost-effective and efficient, making it the preferred choice for many miners.
Process Flow: The process typically involves a three-stage jig machine and multi-stage shaking tables. After grinding, coarse and medium-sized materials undergo jigging, with tailings returning to a vibrating screen for classification. Fine-grained jigging tailings are then sent to shaking tables for further separation, with checks for re-grinding at 1.5-3mm. Tailings are discarded, and slime is treated separately.

2.Scheelite Tungsten Ore:
Flotation: Scheelite ores, often complex and low-grade, are primarily processed using flotation. This method, while more challenging, is essential for extracting tungsten from complex ores.

Advanced Techniques for Enhanced Recovery
For wolframite slime, combining a centrifugal concentrator with shaking tables has proven highly effective. This hybrid approach can significantly improve recovery rates, often achieving 60% or higher. The process involves:

6S Shaker: Initial separation to concentrate tungsten slime.
Centrifugal Concentrator: Further concentration of the slime.
Spiral Chute: Additional separation stages to refine the concentrate.
Flotation Process: Final step to maximize recovery.
This combined method not only enhances recovery but also ensures a higher quality concentrate, making it a preferred choice for many miners.
