Dewatering Solutions by Weir

Mines cannot operate without a robust and flexible dewatering strategy.

As no two mines are the same, each site’s dewatering requirements will vary, with environmental and geological considerations as well as local climatic variations that present unique challenges.

Variations in weather conditions can have a significant effect on open-pit mining in particular, and even mines operating above the water table can be subject to significant influxes of water caused by environmental changes such as heavy rainfall or, in colder climates, melting snow in the springtime.

Therefore, it is essential that the dewatering systems in place have the capacity to handle the maximum potential volume of water inflow to avoid downtime and prevent any risks to safe operation.

A variety of factors dictate the type of dewatering system required for a specific mine. The permeability and porosity of the ground, the amount of surface water, geological features such as underground rivers and seasonal rainfall must all be assessed and factored into a detailed dewatering system before work can begin.

At the forefront of every operator’s requirements from their dewatering equipment is efficiency and reliability, lifetime ownership cost and ease of maintenance.

Cavex® Dewatering Hydrocyclone

The Cavex® dewatering cyclone features the innovative laminar spiral inlet geometry design of the original Cavex® hydrocyclone range, but with additional accessories that allow it to create a dry and stackable product. The hydrocyclone is usually fitted on a boom that can be rotated and adjusted. It also contains a discharge regulator (e.g. fishtail, duckbill, flapper) below the spigot to increase efficiency and deliver a consistent underflow density, regardless of solids content variation in the feed. The Cavex® dewatering cyclone is best suited to tailings, desliming and dewatering applications.
