Coal washings and tailings treatment at their finest

Coal producers everywhere are under pressure to improve everything from washing efficiency and throughput to water recycling and environmental safety. Our separation specialists tackle these challenges based on decades of experience recommending, configuring, and commissioning a wide range of solutions for all types of coal applications.

Efficient fine and coarse dewatering

Producers of all sizes depend on our solutions to achieve continuous, efficient operations in dewatering, thickening, and tailings. Examples range from world-leading companies like Exxaro, Anglo Coal, and Jindal, to many local mines in South Africa, Europe, and the Americas. For coarse dewatering, we supply a range of efficient filter presses to ensure the lowest possible residual moisture and eliminate the need for drying.

For finer particle sizes, our innovative hyperbaric disc filters have helped to set new standards in high-capacity, low-cost coal dewatering.

Cost-effective tailings treatment

The coal industry, of course, faces a number of growing challenges. In some cases success means reducing maintenance with a robust fluid bed dryer, or improving automation through advanced instrumentation, process control, or dynamic simulations of mining operations. Other times, water recovery can be a significant competitive advantage. 

In fact, one coal mine in the Mongolian Gobi desert was able to save more than three million cubic meters of water annually using a highly efficient series of belt presses for tailings dewatering.
