Enhanced Tailings Water Evaporation

The EcoMister Evaporator is the trusted solution for enhanced evaporation in the Mining industry. With over 25 years of experience, it is the most economical solution on the market.

It has been used in mining around the world to dispose of tailings and storm water. Set up over a pond, a lined evaporation area, or recirculated over an open cell to aid in dust suppression.

Automated wind controls mean the evaporator can be left to run autonomously 24/7. It will turn itself on and off to match the wind with the plume and the dimensions of the designated evaporation area.

How does EcoMister work for mining sites?

  • By incorporating enhanced evaporation into your mine water management plan, you can substantially reduce the risk of dam failure and the cost of water management. EcoMister can help by managing the water balance and freeboard within tailing storage facilities, as well as evaporating seasonal runoff, ground and pit water.

Key Features/Benefits

  • When utilizing our automated wind direction and speed controls, the EcoMister Evaporator contains droplet drift, and runs autonomously without the need for valuable operators. 
  • With low cost of operation, the EcoMister Evaporator offers the potential to save millions of dollars in water management cost over the life of a mine.

Low power consumption when compared to alternative water management technologies.

Automated drift control to manage environmental impact.

Eliminate trucking costs.


frequently asked questions

We offer an automated wind speed and wind direction control monitoring system that manages the operation of the evaporator. The controls start and stop the evaporator when the wind blows in and out of pre-set parameters. If the wind blows too hard outside of the allotted zone the evaporator will shut off, if the wind calms the evaporator will restart.

This is dependent on your site. Our units rely on mother nature and local climate conditions. For example our HD30" unit moves 80 gallons per minute, so with an evaporation rate of 50%, this results in 40 gallons per minute. On a larger scale, 40 million US gallons per year results in an evaporation of 20 million gallons per year.

Our evaporator packages can be increased by adding multiple units to one pump package. This allows us to scale up or down to suit the needs of customers' sites.

This figure is highly dependent on energy costs. Typical disposal rate for our North American customers is a tenth of a penny $0.001 per US Gallon OR $0.26 per Cubic Meter.

Our units are purposely designed for minimal maintenance and cost. Nozzle replacement may be required every 2 years, annual lubrication of machinery is recommended, and a major bearing replacement may be required every 5 years.

We are able to tailor the motors to your specific voltage requirements.

Efficiency is the volume of water evaporated as a percentage of the volume pumped aloft.

We have engineered and designed the EcoMister to be the most efficient water evaporator it can be. This means specific water volumes are pumped out of the nozzles which prevents saturation of the plume, creates ideal hang time and drift, creation of precise droplet sizes, and the highest evaporation efficiency.
