TRANSCRIPT
Grinding Aids for Alumina Processing
Developed by SNF as a protective coating of ore stockpiles.
Dust controller for roads.
SNF’s range of liquid coagulants.
Specially designed polyacrylamides to dewater the tailings from the last washer.
A complete range of defoamers that can be used anywhere. Dif-ferent formulations are available.
A surfactant specially adapted to improve performance of vacuum filters.
• Hydroxamated polyacrylamides• Polyacrylate flocculants for Washers• Polysaccharide based flocculants for hydrate thickeners
• Increased bauxite flow rate at the mill of up to 50%• Increased solids content• No change in the particle size of the milled product• No changes in the TAA of the slurries after etching
• Very efficient in fixing dust• Creates a waterproof layeron the treated surface
• Prevents dust emissions fromdirt roads and tracks emittedby vehicles
• Humate removal aid, toreduce organics compoundsbefore settlers
• Saving space• Saving on dikes building• Saving in rehabilitation• Saving in water
• Silicon emulsions• Dispersions
• Increases productivity of vaccum filters• Reduces electricity consumption• Reduces costs of maintenance
• Deposit removal in pre-desilicators• Deposit removal in transfer pipes, flake filters and pumps• Reduction of mill electrical consumption
• Excellent surface coatingproperties• Can be used on mud dam tocontrol caustic dust
• Creates a crust on the road• Allows to save a lot of water
• Iron removal aid, to reduceiron content before safetyfiltration
• Higher safety due to a fasterconsolidation of the slurry• No particles segregation• Avoid huge investmentsagainst dewatering equipment
• Oils• Organic emulsions
• Reduction of filter cloth consumption• 2-3% Reduction in cake moisture• Increased cake dry content
