Metals Mining & Recovery

Water plays a critical yet complex role in mining operations—vital for mineral extraction and processing, yet often limited in availability, especially at remote or arid mine sites.

Crescent Engineering supports mining operations in overcoming water-related challenges with fully integrated water management solutions designed for efficiency, sustainability, and compliance.

Our capabilities include:

Desalination – Converting seawater or brackish sources into reliable freshwater for use in remote or water-scarce locations
Brine Concentration & Crystallization – Treating high-salinity wastewater while enabling the recovery of valuable minerals
Difficult Waste Stream Treatment – Managing complex effluents to enable safe discharge or reuse
Water Reuse & Zero Liquid Discharge (ZLD) – Recycling treated water to reduce freshwater intake or eliminate liquid waste altogether
Regulatory Compliance – Ensuring all discharges meet strict environmental standards
Metals Removal – Targeted removal of heavy metals and other contaminants from process water
Biological Treatment – Applying biological processes to break down organic compounds in wastewater

Crescent Engineering delivers comprehensive desalination and wastewater treatment systems to help mining sites reduce freshwater demand, meet environmental obligations, and unlock greater value from every drop of water on site.

Crescent Approach

We understand the critical role water plays in mining and industrial operations—both as a resource and a challenge. Our integrated water and process solutions are designed to reduce reliance on freshwater, improve operational efficiency, and ensure environmental compliance. Backed by decades of experience and a deep understanding of complex treatment requirements, we deliver tailored systems that meet the specific needs of each site from concept through to long-term operation.

Compliance

We support your project from concept through to high-purity production—ensuring efficiency, reliability, and performance at every stage.

Fully Tested

We optimize metals extraction and purification through targeted bench- and pilot-scale testing, tailored to the specific mineralogy and chemistry of your deposit—ensuring your process meets both recovery and purity targets.
