Iron ore
From concentrate dewatering to tailings treatment, let’s boost your efficiency!
ANDRITZ provides the industry’s most comprehensive range of customized separation solutions and services for iron ore concentrate thickening and filtration, as well as for economical tailings treatment.
Concentrate dewatering: higher throughput, lower costs
Dewatering iron ore concentrates is a crucial step in enhancing their handling and transportation by removing excess water. The selection of a suitable dewatering method depends on various factors, including moisture content, particle size distribution, and downstream process requirements.
At ANDRITZ, we specialize in providing tailored separation solutions to meet the specific needs of iron ore producers. The solutions we offer encompass a wide range of equipment, including high-rate and paste thickeners, filter presses, and pressure drum, vacuum drum, and disc filters. Through years of experience, we have developed this diverse portfolio of reliable equipment, ensuring consistently high throughputs while minimizing energy consumption, spare parts requirements, and downtime. Our expertise enables us to customize dewatering processes, resulting in streamlined operations and efficient resource utilization. These processes are continuously monitored by cutting-edge automation systems to maintain the highest level of effectiveness and productivity.
Efficient dewatering of iron ore tailings: creating more value from waste
With our expertise and cutting-edge technologies for iron ore tailings, we are committed to helping you maximize water recovery while minimizing environmental impact. In order to reduce freshwater consumption, mitigate environmental risks, and achieve sustainable operations, it is crucial to recover as much process water as possible before recirculation. Our refined flocculant dosing, thickening, and filtration solutions produce drier tailings, reliably and efficiently. This helps you optimize storage capacity, reduce transportation costs, minimize the need for freshwater intake, and enhance the overall operational efficiency of your facility at minimum operating costs.
