In the mining process, ore mills generate huge amounts of waste, called tailings. These are most commonly dumped into ponds created from naturally existing valleys, and secured by dams. Other naturally sourced water, such as rainfall or snowmelt that was also collected in the ponds, needs to undergo the same treatment as the tailings.
The composition of the water in the ponds varies, and it is usually rich in sulfates and heavy metals.
The main threat of tailing ponds is the contamination of drinking water sources due to pond overflow or dam failure, or penetration into the aquifer.
IDE’s Solutions for Tailing Ponds
How can tailing ponds be rehabilitated? IDE’s expertise in both membrane and thermal technologies allows it to offer end-to-end solutions for produced water treatment, including tailing ponds – from water to Zero Liquid Discharge (ZLD) level. This includes all necessary pretreatment, ultra-filtration, reverse osmosis, evaporators and crystallizers.
Our modular and pre-fabricated solutions for both RO and thermal solutions are easy to install with minimal on-site setup, and are particularly suited for remote locations.

Tailing Ponds Wastewater Treatment Process
Utilizing Available Coldness from Liquefied Natural Gas LNG Regasification Process for Seawater Desalination
In this article a case study was considered, in which an LNG regasification plant can supply 1750 ton/hr of water-glycol solution at -15°C to be utilized for seawater desalination. The main challenge in this evaluation is being able to provide a desalination solution able to compete with the commonly used RO plants.

Three Pressure Retarded Osmosis PRO Processes
Pressure retarded osmosis (PRO) can be implemented on a number of water types, using different technologies and achieving various power outcomes. This paper presents the three most practical options.
Steam Driven Large Multi Effect MVC (SD MVC) Desalination Process for Lower Energy Consumption and Desalination Costs
This paper will also describe the thermodynamic advantages, the specific investment and desalination costs comparison, and the resulting desalination cost reduction potential of the steam-driven multi effect MVC process.
Three Center Design Implemented in Ashkelon SWRO Plant
This paper presents the three center design implemented in the South Israel (Ashkelon) seawater reverse osmosis (SWRO) desalination facility with guaranteed production capability of 100 Mm3 /year. The facility design is based on the concept of a Three-Center Design: a pumping center, a membrane center and an energy recovery center.
