Metal & Mining

Heavy-duty water treatment for minerals, metals, solids and aggressive wastewater.

THE OPERATING CONTEXT

Complex water. A considered response.

Mines, ore beneficiation plants, blast furnaces, rolling mills and surface finishing facilities produce very different water streams. Abrasive mineral solids, acidic drainage, dissolved metals and rolling oils demand a rugged treatment approach.

Nitaneer engineers treatment and reclamation around solids handling, neutralization and contaminant separation. Equipment and materials are selected for aggressive chemistry, mechanical wear and continuous industrial reuse.

UNDERSTAND THE STREAM

The wastewater challenge

Acidity and corrosion

Mineral oxidation produces acidic leachate with dissolved sulfates and metals, requiring resistant materials and precise pH control.

Abrasive solids

Coal washing, ore comminution and hot rolling carry fines, mineral tailings and mill scale that wear equipment and clog conventional hydraulics.

Complex scrubber wastewater

Gas scrubber streams can contain ammonia, phenols, cyanides, aromatics and metals requiring targeted treatment before reuse.

Key treatment requirements

Abrasive solids and dense slurry separation
Acid-resistant handling and controlled neutralization
Metal precipitation and oil/emulsion separation
Cooling-water conditioning and closed-loop reuse

NITANEER / TREATMENT APPROACH

An integrated treatment train.

Configured around the incoming stream, operating conditions and intended water use.

Mineral solids and mill scale

Grit traps, flocculating clarifiers, hydrocyclones and rapid sand filtration separate dense particles and mill scale.

Acid neutralization and metal removal

Multi-stage lime or caustic dosing neutralizes acidic water and precipitates iron, zinc, copper, nickel and chromium as dewaterable hydroxides.

Oil and toxic-stream treatment

API or plate separators, flotation and emulsion splitting address lubricants. Targeted oxidation treats difficult scrubber contaminants.

Drainage and water reclamation

Acid-resistant pumping, clarification and wetland polishing address mine drainage. Filtration and membrane desalination condition water for cooling and plant reuse.
