Electrochemical solutions and water technologies for mining - Mining
Winning with electrode design to reduce energy costs in traditional processes and UAT Reverse Osmosis (RO) Membrane Filtration Systems to meet any tap or brackish application need. Nickel and cobalt production, precious metal refining (gold, silver), recovery of copper from bleed streams or valuable metals from industrial wastewater, are some of the applications of our titanium DSA anodes.
Power saving, enhanced productivity and operation improvement are the results of using De Nora titanium insoluble anodes in electrowinning applications.
Since 1972, we have worked to improve anode coatings to better serve nickel and cobalt refineries and today we count more than 40.000 De Nora DSA anodes installed in refineries and recovery operation plants, providing high efficiency and optimum quality of recovered metal. We offer a very a wide array of energy-efficient products for the electrowinning of non ferrous metals.
De Nora’s R&D department continues to develop new products for copper and zinc electrowinning. We are constantly looking for innovative solutions that ensure performance improvements under a technical and cost-effectiveness standpoint.
Nickel & Cobalt Electrowinning
We have been one of the first supplier of Mixed Metal Oxide anodes for chlorine leach process of nickel, and nowadays develops, engineers and manufactures advanced solutions for mixed chloride/sulfate electrolyte.
Mixed metal oxide (MMO)-coating titanium anodes are gaining acceptance even in copper electrowinning versus lead alloy anodes, still fitting the majority of commercial metal electrowinning plants.
INDUSTRIAL PROCESS WATER TREATMENT
Water is an integral part of the mining and metal production process. Large quantities of water are required in sufficiently high quality for all areas of mine operations from exploration, mining, processing, smelting and refining. The requirement to provide treated raw water through to water reuse.
- Treat raw water for pre-treatment
- Remove suspended solids, colloidals, organics, iron, manganese and other contaminants from raw water source
- Provide high quality water for process or boiler feed using Reverse Osmosis
- Treat and reduce effects of Acid Rock Drainage using reverse osmosis
- Treat cooling tower water or process water using disinfection technologies such as sodium hypochlorite
- Treat wastewater
- Treat contaminated water for environmental discharge or reuse using membranes
Using high quality components, the skid-mounted De Nora UATReverse Osmosis (RO) systems are engineered to effectively produce treated water, free of particulate matter or contaminants.
