Historic Mine Uses Wastewater Ion Exchange Service for Copper and Cobalt Removal

The Minnesota Department of Natural Resources (DNR) needed to meet stringent discharge limits for copper and cobalt in their Soudan Mine facility. The facility is a former iron mine that was converted to a state park. Copper and cobalt from surrounding geological formations leach into water and exceed current discharge limits.

Mining Company Uses Mobile Filtration for the Removal of Iron From Raw Water

A Southern mining company needed rapid response to an iron fouling problem that affected their process. The raw water used for the mining process contained high levels of iron (5-8 ppm) resulting in equipment fouling and high maintenance costs. This significantly reduced the rate at which the plant could develop the caverns, impacting both its on-line date and operating costs.

Mobile Water Treatment Pilot for Mining Industry Leads to Full-Scale System

The original plant design at this location was found to lack proper consideration of the pond’s future contaminants and balance. Specific contaminants of concern and maximum environmental permit goals for the same were < 0.5ppm Ammonia as N and < 0.1ppm Free Cyanide.

Nevada Goldfields' Wastewater Treatment System Uses Reverse Osmosis and Ion Exchange to Meet Stringent Metal Limits

In order to expand operations and maintain a water balance in South Carolina’s wet climate, Nevada Goldfields’ Barite Hills gold mining operation required a treatment plant to handle its wastewater. At this mining site, the company extracts gold from soil using a high pH cyanide leaching solution. The process generated large volumes of cyanide and metal laden wastewater, which they had been storing on-site.

PACT® System Enabled Cleveland Refinery to Meet OCPSF Pre-Treatment Rules

PACT system enables Cleveland refinery to meet new OCPSF pre-treatment requirements, remove COD and organics from wastewater.

Ultra High Recovery Integrated Membrane System for Mine Drainage Water Treatment

As mining industry sites continuously expand into wilderness locations, developers are faced with the challenge of minimizing the impact on the local environment. Typically, large volumes of water are produced from drainage and run off at the facility containing various contaminants from heavy metals, selenium to chlorides.
