Diemme Filtration's main applications in Mining & Metals

With the products of Diemme® Filtration we will find a solutions to the filtration of sludge and slurry from the mining sector. We continuously look for the best filtration parameters and we optimise the filtration process for each application.
  • Filtration of concentrates coming from beneficiation process after flotation - Non ferrous metals (copper, zinc, lead, molybdenum, chromium, tin, aluminium)  - Ferrous metals (magnetite, hematite, pyrite) - Noble metals (gold, silver, palladium, platinum) - Rare metals (osmium, ruthenium, gallium, germanium) - Coal - Phosphates
  • Filtration from leaching/purification - Non ferrous metals (copper, lead, zinc, cobalt, nickel, manganese, boron, lithium, arsenic, antimony, titanium, cadmium, vanadium) - Noble metals (gold with cyanides, bioleaching gold) - Aggregate minerals (kaolin, feldspars, clay, silicates, quartzite, carbonates)
  • Tailings Filtration and  waste water treatment plant (WWTP) - Non ferrous metals (copper, zinc, lead, red mud, gold, gold de-cyaniding, coal)
  • Filtration from wet fume treatment (pyrometallurgy) - Zinc oxide - Various oxides - Arsenic sulphide – Aluminosilicates

Johnson Screen's main applications in Mining & Metals

Johnson Screens® has developed world class proprietary Vee-Wire® and Polyurethane manufacturing processes. Along with in-house product innovation, "Fit for Duty" material selection, mineral sizing, cleaning, and de-watering know-how; we are well positioned to offer a comprehensive range of products and services for the mining screen applications used in coal, iron ore, gold, copper, phosphate, lead, zinc, bauxite, sand, gravel and many more.
Our screening systems are customized to:

  • Remove moisture in coal preparation, which lowers coal heating value. Also, too much moisture leads to handling/freezing problems, and increased transportation costs;
  • Improve density media recovery in coal preparation to optimise process costs;
  • Satisfy classification and purity specifications dictated by the metals and minerals markets;
  • Ensure correct particle reporting will maximise asset efficiency in your downstream processes;
  • Eliminate pegging and blinding (near size material nesting in the screen openings) will improve process production yield and efficiency.
