Northfil

We operate a large mill and 2 mines producing a serpentine consisting of antigorite, a hydrous magnesium silicate. This material has been found to be a very useful filler/additive in the manufacture of tires and PVC plastic as it solves several problems associated with other additives. Some have also used it as an asbestos substitute as it has similar properties.We are capable of exporting large amounts of this material 1000-80,000 ton orders and currently have samples and a sales agent in Guangzhou. We also have started mining vermiculite and are willing to export custom orders (www.northfil.com). We are also always available to do custom milling or toll grinding.NORTHFIL -325 Technical Data Analysis Chemical ASTM Methods % by weightSilica (Sio2) Whole Rock Analysis- XRD 30.300%Alumin Alumina (AI2O3) 3.400%Ferric Oxide (Fe2O3) 7.800%Magne Magnesia (MgO) 31.600%Trace Elements:Lime (CaO) 3.600% Chromic Oxide (Cr2O3) 0.210% K20 0.130% H2O, bonded 13.550%Sodium Oxide (Na2O) 0.100% Typical Physical Data:Appearance Fine Light Gray Powder Brightness(Photo Voltmeter) 68 - 69Chemical Family-Serpentine, with minor amounts of other Mg-silicates Mg3Si2O5(OH)4Mg3Si4O10(OH)2 Oil Absorption(ASTM D1483-95) 38 lbs/ 100lbs38 gm / 100 gmLoss On Ignition 13.550% Minus 325 mesh Tyler / -45 micron 97.6 % passingBulk Density: ml/100gm - Dry 170-190 Moisture (%)(Gravimetric at 105C) 0.4Loose lb/ft³ 37-32 Morphology(Optical Microscopy) Acicular - EquantTapped lb/ft³ 47.5 Refractive Index(Immersion Oil) 1.57Charge Electropositive Mohs Hardness(Manual) 2.5 pH (Paste pH) 9.34 Aspect Ratio(Automated Digital Imaging) 1:16Specific Gravity(Gas Pycnometer) 2.45 Median Particle Size(Cyclosizer/Sedigraph) 10 micronMelting Point > 1385C Water Solubility 0.0038 gm/100ml NORTHFIL -325 (45 Microns)NON-TOXIC, ENVIRONMENTALLY SAFE MINERAL FILLER POWDER, CONTAINING NO FREE SILICA.
